Common Reasons for Water Heater Running Out of Hot Water
A properly functioning water heater should provide sufficient hot water for typical household needs throughout the day. When your system consistently fails to meet demand, several mechanical, operational, or design factors may be responsible.
To identify the cause, pay attention to:
when shortages occur;
how quickly hot water depletes;
whether the issue developed gradually or appeared suddenly.
Sediment Accumulation Inside the Tank
Sediment accumulation ranks among the most frequent culprits behind diminished hot water capacity.
Over time:
minerals like calcium and magnesium separate from heated water;
these minerals settle at the bottom of the tank;
a sediment layer forms between the heating element and the water.
This layer:
reduces heating efficiency;
decreases usable tank volume;
forces the system to work harder while producing less hot water.
Thermostat Problems
Thermostat problems also commonly cause hot water shortages.
Most systems include:
two thermostats on electric models; one gas valve control on gas units.
When these controls:
malfunction;
drift out of calibration;
are set too low;
the water may never reach a comfortable temperature.
Heating Element Failures
Heating element failures in electric water heaters create immediate and noticeable hot water shortages.
Typical scenarios include:
upper element working, lower element failed;
partial heating of the tank;
hot water available briefly, then gone.
This is a common reason water running out of hot water heater problems appear suddenly.
New Hot Water Heater Running Out of Hot Water Immediately
A new hot water heater running out of hot water shortly after installation is especially frustrating.
Common causes include:
1. Incorrect Sizing
Professional installers calculate capacity based on:
household size;
number of bathrooms;
simultaneous usage.
If usage has changed, the new unit may be too small.
managing peak water usage. These actions extend system lifespan and stabilize performance.
Conclusion
Hot water shortages stem from many causes, including sediment buildup, component failure, improper sizing, and age-related decline. Whether the issue is water heater running out of hot water, fast depletion, or inconsistent recovery, systematic diagnosis allows effective solutions.
Regular maintenance and professional support ensure reliable hot water and long-term system efficiency.
Brown or Smelly Water: What It Means and Why It Happens
Turning on your tap and encountering discolored or foul-smelling water can be alarming and unpleasant.
These water quality issues are more common than you might think, affecting homeowners across various regions and plumbing systems.
Understanding the causes behind these problems and knowing when to call a professional plumber can help you address issues quickly, protect your health, and maintain your home’s plumbing infrastructure.
This comprehensive guide will help you identify different types of water quality problems and determine the appropriate course of action.
Understanding brown water problems
Brown water flowing from your taps is often one of the most visually disturbing plumbing issues homeowners encounter.
The discoloration typically ranges from light tan to dark brown, sometimes appearing almost rusty red.
This issue can affect all water outlets in your home or may be isolated to specific faucets, and understanding the pattern can help identify the underlying cause.
The most common reason for brown water from tap fixtures is rust and sediment in your plumbing system.
Older homes with galvanized steel or iron pipes are particularly susceptible to this problem.
Over time, these metal pipes corrode from the inside, creating rust particles that mix with the water supply.
When water pressure changes or the system experiences sudden flow variations, these accumulated sediments can dislodge and travel through your pipes, eventually reaching your faucets.
Municipal water main work or repairs in your area can also cause temporary brown water issues. When utility companies flush water mains, perform repairs, or change water pressure in the distribution system, sediment that has settled in public water lines can become disturbed.
This sediment then travels through the municipal system into your home’s plumbing. While usually temporary, this type of discoloration can persist for several hours or even days after utility work concludes.
Why is my water brown? Common causes explained
If you’re asking yourself why is my water brown, several factors could be responsible. Beyond pipe corrosion and municipal maintenance, other causes include water heater problems, well water contamination, and seasonal changes affecting water sources.
Each cause has distinct characteristics that can help you diagnose the issue.
Water heater sediment buildup frequently causes brown hot water while cold water remains clear.
Minerals and sediment naturally accumulate at the bottom of water heater tanks over time. When the sediment layer becomes thick enough, it can break apart and enter your hot water lines, causing discoloration.
his problem typically worsens gradually and may be accompanied by rumbling or popping sounds from the water heater as it operates.
For homes with well water systems, brown discoloration might indicate iron or manganese contamination, surface water infiltration, or disturbances to the well itself.
Heavy rainfall can wash sediment and organic matter into wells, while drought conditions might lower water tables enough to draw in sediment-rich water from deeper levels. Changes in groundwater chemistry can also mobilize naturally occurring minerals that cause discoloration.
Seasonal variations sometimes affect municipal water supplies, particularly in areas drawing from surface water sources like rivers and lakes. Spring runoff and autumn leaf decay can introduce organic matter and minerals into water treatment facilities.
While treatment plants work to remove these contaminants, some discoloration may occasionally reach residential areas during peak seasonal changes.
Dealing with smelly water issues
Smelly water presents a different but equally concerning problem. Water odors can range from mild to overpowering and may indicate various underlying issues, some more serious than others. The specific smell often provides important clues about the contamination source and the urgency of the situation.
Smelly water from tap fixtures most commonly smells like rotten eggs, which indicates hydrogen sulfide gas presence. This sulfurous odor can result from several sources including bacterial activity in water heaters, reactions between water and magnesium anode rods in heater tanks, or naturally occurring sulfur compounds in groundwater.
While unpleasant, low levels of hydrogen sulfide are generally not harmful, though higher concentrations can pose health risks and corrode plumbing fixtures.
A bleach or chlorine smell typically indicates excessive disinfectant in municipal water supplies.
Water treatment facilities add chlorine to kill bacteria and pathogens, but sometimes chlorine levels spike temporarily, especially after system maintenance or during periods of high contamination risk. While properly chlorinated water is safe to drink, the strong smell can be off-putting and may irritate sensitive individuals.
Musty, earthy, or fishy odors often point to algae, bacteria, or organic matter in the water supply. These smells are more common with surface water sources and typically intensify during warmer months when algae blooms proliferate.
While usually not indicating dangerous contamination, these odors suggest water quality issues that warrant attention and possible treatment system adjustments.
Smelly hot water specific concerns
When you notice smelly hot water but cold water smells fine, the problem almost certainly originates in your water heater. This distinction is crucial for diagnosis because it narrows the issue to a single appliance rather than your entire plumbing system or water source.
Several water heater components and conditions can create odor problems.The magnesium anode rod inside water heaters is designed to prevent tank corrosion by attracting corrosive elements in the water. However, sulfate-reducing bacteria sometimes colonize water heaters and react with the magnesium anode rod, producing hydrogen sulfide gas. This reaction creates the characteristic rotten egg smell that many homeowners associate with hot water problems.
Water heaters that sit unused for extended periods or operate at low temperatures provide ideal conditions for bacterial growth. Bacteria thrive in warm, stagnant environments, and water heaters set below 140°F may not reach temperatures sufficient to kill microorganisms. Vacation homes, guest bathrooms, or systems with malfunctioning thermostats commonly develop bacterial odor problems for this reason.
Temperature and pressure relief valve issues, sediment accumulation, and corroding tank interiors can also contribute to hot water odors. As tanks age, protective liners deteriorate, exposing metal surfaces that react with water chemistry. Combined with sediment that creates anaerobic pockets where bacteria flourish, older water heaters become increasingly prone to odor generation.
Smelly water in bottom of dishwasher problems
Finding smelly water in bottom of dishwasher units is another common complaint related to water odor issues. This stagnant water often develops unpleasant smells between wash cycles, particularly if dishes sit for several days before the dishwasher runs. Several factors contribute to this specific problem, most relating to drainage and cleaning habits.
Dishwashers rely on proper drainage to remove food particles and wastewater after each cycle. When drain hoses become kinked, clogged, or improperly installed, water may pool at the bottom of the dishwasher tub. This standing water provides an ideal environment for bacteria and mold growth, quickly developing foul odors that transfer to dishes during subsequent wash cycles.
Food debris trapped in filters, spray arms, and along door gaskets decomposes over time, creating unpleasant smells. Many homeowners don’t realize dishwashers require regular cleaning beyond simply running wash cycles. Accumulated food particles, grease, and detergent residue create biofilm layers where bacteria proliferate, generating persistent odors that ordinary wash cycles cannot eliminate.
Garbage disposal connections sometimes allow sewer gases to enter dishwasher drain lines when air gaps or high loops are absent or improperly installed. This plumbing deficiency permits odorous gases to travel backward through the drain hose into the dishwasher, creating smells that seem to originate from the appliance itself when the actual problem lies in drain system design.
How to get rid of smelly water solutions
Addressing how to get rid of smelly water depends entirely on identifying the underlying cause. Different problems require different solutions, ranging from simple DIY fixes to professional plumbing interventions. Starting with the least invasive approaches makes sense before escalating to more complex solutions.
For hydrogen sulfide smells from water heaters, flushing the tank to remove sediment and bacteria can help. Temporarily raising water temperature to 160°F for several hours kills bacteria, though you must remember to reduce temperature afterward to prevent scalding hazards. Replacing magnesium anode rods with aluminum-zinc alternatives eliminates the chemical reaction that produces hydrogen sulfide when sulfate-reducing bacteria are present.
When asking how do you get rid of smelly water from municipal sources, sometimes the simplest solution is running faucets for several minutes to flush out stagnant water in pipes. If chlorine smell is the issue, filling a pitcher and refrigerating it allows chlorine to dissipate naturally. Carbon filters effectively remove chlorine taste and odor while also addressing many organic compounds that cause earthy or musty smells.
Well water odor problems may require more comprehensive solutions including chlorination systems, aeration units, or specialized filtration equipment. Professional water testing identifies specific contaminants present, allowing targeted treatment approaches. Shocking wells with chlorine bleach can temporarily eliminate bacterial contamination, though recurring problems indicate the need for permanent treatment systems.
How to fix smelly water from faucet and when to call professionals
Learning how to fix smelly water from faucet outlets starts with determining whether the problem is localized or system-wide. Running both hot and cold water from multiple fixtures throughout your home helps establish the problem’s scope. If only one faucet produces smelly water, the issue likely involves that specific fixture or its immediate supply line rather than your entire plumbing system.
Aerator cleaning sometimes resolves localized odor problems. Faucet aerators trap debris and minerals, creating small pockets where bacteria can grow and produce odors. Removing and soaking aerators in vinegar solution dissolves mineral deposits and kills bacteria. For persistent problems, replacing aerators entirely is inexpensive and often effective.
However, many water smelly problems require professional intervention.
If discoloration or odors persist after basic troubleshooting, worsen over time, or appear suddenly without explanation, calling a licensed plumber is advisable.
Professionals have diagnostic tools and expertise to identify hidden problems that homeowners cannot detect, including corroded pipes within walls, failing water heaters, or contaminated well systems.
Significant brown water issues, especially when accompanied by pressure changes or visible particles, may indicate serious pipe deterioration requiring replacement.
Similarly, strong sulfur odors that don’t respond to water heater maintenance might signal well contamination or sewer line problems that only professionals can properly address. Health concerns should always prompt immediate professional consultation, as some water contaminants pose serious health risks that aren’t always detectable by smell or appearance alone.
Conclusion
Water quality problems like brown discoloration and unpleasant odors are common plumbing issues with various potential causes. While some situations allow for simple DIY solutions, others require professional plumbing expertise to diagnose and resolve properly.
Understanding the difference between temporary nuisances and serious problems helps homeowners make informed decisions about when to attempt fixes themselves and when to call qualified plumbers. Regular plumbing maintenance, prompt attention to water quality changes, and professional inspections help prevent minor issues from becoming major problems, ensuring your home’s water remains safe, clean, and pleasant for daily use.
Why Pipes Are Making Noises: Causes, Risks, and Professional Solutions
When homeowners notice that pipes keep making noises, it often starts as a minor annoyance but quickly turns into a concern. Many clients contact us saying that their pipes started making loud noises suddenly, even though nothing has changed in daily water usage.
Others report that my pipes are making noises mainly at night, after flushing the toilet, or when the heating system turns on.
From an expert plumbing perspective, pipes making noises is not a random issue. These sounds are a signal that something inside the plumbing system needs attention. Understanding what causes noises in pipes allows you to respond early, avoid damage, and maintain a safe and efficient system.
Common Plumbing Noises in Pipes and What They Mean
Plumbing systems can produce different sounds depending on the underlying issue. Identifying the type of noise is the first step toward an effective solution.
Banging and Knocking Pipes
If pipes are making strange noises such as loud bangs or sharp knocks, the most common cause is water hammer. This happens when water flow stops abruptly, forcing pressure back through the system.
Typical reasons include:
Sudden valve closure;
Excessive water pressure;
Failed or missing air chambers.
Over time, water hammer can loosen fittings, stress joints, and increase the risk of leaks.
Gurgling Noises in Water Pipes
Many homeowners ask, why are my water pipes making gurgling noises? Gurgling sounds usually point to airflow problems or partial blockages.
Common causes of noises in drain pipes include:
Clogged drain lines;
Improper venting;
Debris buildup inside pipes.
These noises in pipes are often heard after flushing toilets, draining sinks, or during heavy water use.
Rattling and Vibrating Pipes
Rattling is one of the most common plumbing noises in pipes, especially in older buildings. When pipes are not properly secured, water movement causes them to vibrate against walls, joists, or other surfaces.
This issue often appears when:
Pipes lack proper mounting brackets;
Fasteners have loosened over time;
Pipe insulation is missing or worn.
Creaky and Squeaky Pipe Noises
Creaky pipes noises are usually related to thermal expansion. As hot water flows, pipes expand and rub against surrounding materials. When they cool, they contract, producing repetitive squeaks or creaks.
These noises in water pipes are not dangerous but can worsen if pipes are tightly constrained without insulation.
What Causes Noises in Pipes?
From a professional plumbing standpoint, the most frequent causes include:
High or fluctuating water pressure;
Trapped air in supply or drain systems;
Loose fittings or unsecured pipe runs;
Thermal expansion from hot water or heating systems;
Blockages, sludge, or sediment buildup.
If pipes started making loud noises, it usually means one of these factors has gradually reached a critical point.
How to Fix Pipes Making Noises
1. Secure and Insulate Pipework
One of the simplest solutions is properly securing exposed pipes. Adding pipe clips, brackets, or insulation can significantly reduce vibration and pipes making noises during normal operation.
This is especially effective for:
Rattling supply lines;
Vibrating drain pipes;
Creaking caused by friction.
2. Adjust Water Pressure
High pressure forces water through pipes too aggressively, increasing noise and wear. Installing or adjusting a pressure-reducing valve can eliminate many noises in pipes and protect fixtures and appliances.
3. Address Water Hammer
If your pipes are making strange noises such as loud bangs, installing water hammer arrestors can absorb pressure shocks and prevent long-term damage.
In some cases, resetting air chambers may also help, but persistent hammering should be professionally evaluated.
4. Clear Blockages and Improve Drain Flow
Persistent noises in drain pipes often indicate blockages or sludge buildup. Professional drain cleaning removes debris safely and restores proper airflow and drainage.
This approach prevents:
Gurgling sounds;
Slow drainage;
Pressure imbalance in the system.
When Pipe Noises Become a Serious Problem
While some plumbing noises in pipes are harmless, others can signal risks that should not be ignored.
Professional Plumbing Services That Help Eliminate Pipe Noises
In many cases, resolving noisy pipes requires targeted plumbing services rather than temporary fixes. Depending on the cause, professional solutions may include:
Installation of pressure regulators or water hammer arrestors;
Securing and insulating exposed pipework;
Repairing or replacing faulty valves and fittings.
Expert diagnosis ensures the root cause is addressed, not just the symptom.
Final Thoughts from Plumbing Experts
If my pipes are making noises, it’s never something to ignore. Each sound — whether banging, gurgling, rattling, or creaking — provides valuable insight into what’s happening inside the system. By understanding what causes noises in pipes and acting early, homeowners can avoid structural damage, water loss, and unnecessary stress.
A quiet plumbing system isn’t just about comfort — it’s a sign of safety, efficiency, and long-term reliability.
As the snow melts and the ground thaws, most Canadian homeowners naturally shift their focus to landscaping, gardening, and outdoor projects. However, the transition from winter to summer puts a unique and often underestimated strain on your home’s infrastructure. Increased water usage, rapid root growth, and severe summer storms can all lead to unexpected disasters if you aren’t prepared.
To help you enjoy a worry-free season, we have compiled a comprehensive, professional plumbing checklist for homeowners. Following these detailed steps can save you from costly emergency calls in the middle of a July heatwave and ensure your summer is filled with relaxation, not repairs.
1. Inspect Outdoor Faucets and Hose Bibs
Your outdoor taps have likely been dormant for months. During this time, the freeze-thaw cycle of winter can cause “silent leaks” inside the pipes that feed these taps, even if you drained them last autumn.
Start your season by carefully checking outdoor faucets for leaks. Here is how to do it properly:
Visual Inspection: Before turning anything on, check the exterior tap for rust or mineral buildup.
The Thumb Test: Place your thumb over the spigot opening. If you turn the water on and can stop the flow easily with your thumb, the water pressure is likely escaping through a crack somewhere else in the pipe.
The Hose Test: Attach a garden hose and turn the water on full. If you see water dripping from the handle stem or, worse, damp spots appearing on your basement drywall inside, the pipe may have cracked during a freeze. Addressing this early helps avoid significant water loss and possible foundation issues.
2. Irrigation and Sprinklers: Tune-Up Time
A lush lawn requires a well-functioning irrigation system, but turning it on after a long winter isn’t as simple as flipping a switch. Before you set your timer for the season, thorough sprinkler system maintenance is mandatory.
Walk your property while the system runs through a full cycle. Look for:
Misaligned Heads: Ensure sprayers are directing water onto the grass, not your driveway or house siding.
Broken Components: Look for heads that are cracked (shooting geysers of water) or failing to pop up due to debris.
Underground Leaks: Keep an eye out for soft, soggy patches of grass or areas that are unusually green compared to the rest of the lawn. This often indicates a cracked underground pipe, which can silently drive up your water bill by hundreds of dollars.
3. The Hidden Threat: Sewer Lines
Summer is the prime growing season for trees and shrubs. Seeking moisture and nutrients, aggressive roots can infiltrate even tiny cracks in your main sewer line, causing blockages and backups.
If you live in an older neighbourhood with mature trees, you are at a higher risk. Many homeowners hesitate because of the price, but a sewer line inspection cost (usually a few hundred dollars) is a small price to pay for peace of mind compared to the thousands required to clean up a sewage flood. A professional Drain Camera Inspection can spot root intrusion deep within the pipe before it causes a complete sewage backup into your basement. Watch out for warning signs like slow-draining bathtubs or gurgling sounds from your toilet.
4. Kitchen Disposal Care
Summer brings barbecues, corn on the cob, and fresh fruit salads. Unfortunately, it also brings garbage disposal smells. High temperatures accelerate food decomposition in your pipes, leading to unpleasant odours that can permeate your kitchen.
To keep your disposal running smoothly:
Watch What You Grind: Avoid putting fibrous materials (corn husks, celery, watermelon rinds) down the disposal, as they can tangle the blades. Also, never pour grease from your summer BBQ down the drain—it solidifies and causes stubborn clogs.
Deodorize: If odours develop, run the disposal with cold water and grind a cup of ice cubes mixed with lemon or orange peels. The ice scours the blades, while the citrus neutralizes bacteria.
5. Storm Readiness: Sump Pumps
Summer thunderstorms in Canada can deliver large amounts of water in minutes. When the ground is saturated, your sump pump becomes your basement’s last line of defense against flooding. A seized pump during a storm guarantees a flooded basement. If your unit is over 7 years old, schedule a Sump Pump Installation & Replacement before heavy rains begin.
General summer plumbing maintenance must include testing your sump pump mechanism.
The Bucket Test: Pour a bucket of water slowly into the sump pit to ensure the float switch activates automatically and pumps the water out effectively.
Check the Discharge: Ensure the drainage pipe outside is clear of debris and directs water away from your foundation.
Power Backup: Consider installing a battery backup system. Summer storms often bring power outages, and a seized or unpowered pump during a heavy rainstorm guarantees a flooded basement.
6. Vacation Mode Strategy
Heading to the cottage or flying abroad for a well-deserved break? Don’t leave your house vulnerable while you are gone. A solid vacation plumbing checklist involves more than just locking the doors.
Shut Off the Main Valve: This is the only 100% guarantee against floods while you are away. If a pipe bursts while you are in Europe, the damage could be catastrophic.
Water Heater: Turn the dial to “Vacation” mode. This keeps the pilot light on but stops heating water unnecessarily, saving you money on energy bills.
Double-Check Drains: Ensure all taps are tightly closed and no toilets are running.
Ask a Neighbor: Have someone check on the house periodically to ensure there are no visible leaks or issues.
Conclusion
A little preparation now helps you relax later. By addressing these tasks early in the season, you ensure your home runs all summer smoothly.

FAQ
Why does my washing machine smell in the summer?
Humidity encourages mold growth in the rubber seal of front-loaders. Leave the door open between loads to allow it to dry out.
Can I pour grease down the drain if I run hot water?
Never. Grease is liquid at high temperatures but solidifies deep in your pipes when it cools (especially underground), creating stubborn clogs. Always dispose of BBQ grease in a container.
How do I know if I have a root intrusion in my sewer?
Common signs include gurgling toilets, slow-draining bathtubs, or sewage smells in the yard.
What is the best way to clean outdoor drains?
Clear leaves and debris from patio or driveway drains to ensure summer rain can flow freely away from your foundation.
For many Canadian homeowners, “going green” is no longer just an environmental statement—it is a financial necessity. With rising utility rates and carbon taxes, the cost of running a home is increasing. Plumbing fixtures, often overlooked, are actually some of the biggest energy and water consumers in your house.
But does energy efficient plumbing save money in the real world, or is it just marketing hype? The truth lies in the data. Modernizing your plumbing infrastructure can yield a significant Return on Investment (ROI) while improving your home’s functionality. Let’s dive into the technical and financial benefits of these upgrades.
1. Tankless Water Heaters: Efficiency on Demand
The biggest energy hog in your basement is likely your water heater. Traditional tanks keep 40–60 gallons of water hot 24 hours a day, even when you are asleep or at work. This “standby loss” is a massive waste of gas or electricity.
To decide if an upgrade is right for your home, it is essential to weigh the tankless water heater pros and cons.
The Pros: Tankless units heat water only when needed. When you open a tap, powerful burners ignite instantly. This eliminates standby energy loss entirely, reducing energy use by up to 30%. Additionally, they are wall-mounted, saving valuable floor space.
The Cons: They have a higher initial cost compared to a standard tank, and retrofitting may necessitate upgrading gas lines.
Pro Tip: To protect this investment from mineral buildup and ensure longevity, consider pairing your new heater with professional Water Softener Installation.
2. Modern Toilets: High Performance, Low Waste
Back in the 1990s, “low-flow” toilets often experienced frequent blockages. Fortunately, technology has advanced considerably since then. Today, High-Efficiency Toilets feature improved hydraulic systems and larger trap ways.
When evaluating low flow toilets pros and cons, it becomes clear that the technology has matured:
Efficiency: Flushing makes up nearly 30% of average indoor water use. Modern units flush effectively using only 4.8 litres or less.
Dual Flush: Many models now feature dual flush options—a light flush (3L) for liquid waste and a full flush for solids. This can save a family of four more than 50,000 litres of water each year.
However, modern designs have improved significantly. If your current unit is constantly running or leaking, a simple Toilet Repair might fix it, but upgrading to a high-efficiency model is often the more cost-effective long-term solution.
3. Faucets and Fixtures: The Hidden Savings
You don’t have to tear down walls to enjoy the benefits of low flow fixtures. Swapping out an old shower head (which uses 9.5 liters per minute) for a Water Sense-certified one (just 7.6 liters per minute) can reduce your water use by 20%.
Best of all, since you’re using less hot water, you’ll also see savings on your gas or electric bill. It’s a wonderful double benefit that helps the new fixture pay for itself in just a few months.
4. Smart Leak Detectors: Protection and Peace of Mind
Efficiency isn’t just about lowering consumption; it’s about preventing resource waste. A tiny pinhole leak can waste thousands of litres of water before a damp patch appears.
The smart water leak detector benefits go far beyond simple conservation:
Real-time Monitoring: These WiFi-connected devices monitor flow rates and detect unusual activity, like a burst pipe when you’re not home.
Automated Safety: They can instantly turn off your main water supply and notify your phone.
Insurance Discounts: Many insurance companies now offer discounts on premiums for homes equipped with these systems.
5. The Bigger Picture: Sustainability
Let’s take a moment to look beyond our utility bills. The environmental impact of water conservation is profound and creates a positive ripple effect in our community.
Treating and pumping water require a lot of energy. By being conscious of our water consumption at home and using less, we reduce strain on local infrastructure and decrease our carbon footprint, helping create a cleaner, healthier environment.
Thinking about upgrades? Investing in energy-efficient plumbing is a great step toward increasing your home’s value and efficiency. Whether you’re considering replacing your water heater or upgrading to smarter faucets, the friendly experts at POM Plumbing are ready to assist. We can guide you through available rebates and recommend the best products suited to your needs.
FAQ
How long does it take for a tankless heater to pay for itself?
On average, the energy savings pay for the installation difference in about 3 to 5 years, but the unit lasts 20+ years (twice as long as a tank).
Will a low-flow shower head feel like a drizzle?
No. Modern aerators mix air into the water stream, increasing the pressure velocity. You get a strong, satisfying spray while using significantly less water.
Are smart leak detectors hard to install?
Clamp-on models are DIY-friendly, but the most effective models (with auto-shutoff valves) require professional installation into the main water line.
We have all been there: you are enjoying a warm, relaxing shower, and suddenly, without warning, the water turns cold or dangerously hot. You jump back, waiting for the temperature to stabilize, wondering what just happened.
This phenomenon is known as “thermal shock,” and it is not just a nuisance; it is a sign that your plumbing system lacks a critical component or that a specific part has failed. If you’re wondering why your shower water randomly switches between hot and cold, the answer often lies inside your wall within a component called a mixing valve.
In this guide, we will break down the mechanics of shower valves, explain why modern homes are required to have them, and help you decide if it is time for an upgrade.
What Is a Mixing Valve? The Mechanics Explained
To understand the solution, we must first define the device. What is a mixing valve? In technical terms, it is the heart of your shower faucet. It is a brass component installed behind the shower handle that blends the hot water from your water heater with the cold water from your main supply line.
But a modern mixing valve does more than just blend; it regulates. Shower mixing valve explained simply: It makes sure the water temperature stays steady even if pressures in your home’s pipes change. In larger buildings, it works together with Riser and Zone Valves Replacement to control overall building pressure.
Symptoms of a Missing or Faulty Valve
How do you know if your home lacks this protection or if your existing valve has a bad cartridge? Look for these three signs:
The “Toilet Flush” Effect. This is the most common sign. If your shower turns cold when the toilet flushes (or becomes very hot), your plumbing system is not balancing pressure properly. When the toilet refills, it uses a large amount of cold water, causing a pressure drop in the cold line. Without a functioning mixing valve, hot water then takes over, potentially scalding anyone in the shower.
Constant Temperature Adjusting. If your shower temperature varies during use and you frequently need to adjust the handle left or right, the internal cartridge may be clogged with mineral deposits or worn out. This issue is common in areas with hard water.
Delayed Reaction. Does the water take a moment to start flowing when you turn the handle? That “spongy” feeling is often a sign that the internal mechanism might be beginning to fail.
Comparing Technologies: Thermostatic vs. Pressure Balance
Not all valves are created equal. When upgrading, you will face a choice between two main technologies. Understanding the thermostatic mixing valve vs pressure balance difference is crucial for your comfort and budget.
Option A: Pressure Balance Valve (The Standard)
How it works: It senses changes in water pressure. When cold pressure drops, a piston inside shifts to block some hot water.
Pros: Lower cost, reliable, standard in most North American homes.
Cons: It only controls the ratio, not the exact temperature. If you turn down the volume, the temperature might shift.
Option B: Thermostatic Mixing Valve (The Upgrade)
How it works: It uses a wax element that expands and contracts when heated. It automatically adjusts hot and cold inputs to keep a specific temperature (e.g., 38 °C).
Pros: You have complete control. You can adjust the temperature with one handle and the water flow with another. Perfect for “rain” shower heads.
Cons: Higher startup cost.
Safety First: Preventing Scalding
The most critical reason to address these issues is safety. Preventing shower scalding is a top priority, especially for households with children or elderly family members who may have slower reaction times. A sudden burst of hot water can cause serious burns in seconds.
Modern building codes require anti-scald protection. If you live in an older home with two-handle faucets (one for hot, one for cold), you might not have this protection. Installing an anti-scald valve shower system is one of the most effective safety upgrades you can make.
Conclusion: Do You Need a Plumber?
If you’re dealing with these issues, you have two options: replace the internal cartridge (repair) or install a new valve body (renovation). While changing a cartridge can often be a DIY project, replacing the valve usually involves soldering and working behind the wall.
Don’t put up with the “shower dance” any longer. Reach out to POM Plumbing today! We’re here to assess your system and bring back comfort to your bathroom.
FAQ
Can a mixing valve be adjusted?
Yes. Most modern valves have a rotational limit stop (a plastic ring) under the handle. Adjusting this can allow more hot water into the mix if your shower feels lukewarm.
How long does a shower cartridge last?
Typically, 10 to 15 years. However, hard water can significantly shorten this lifespan by causing mineral buildup that clogs the piston.
Why is my water pressure low only in the shower?
If other faucets are functioning properly, the issue is likely debris inside the mixing valve or a clogged shower head, rather than a problem with your main water line.
Your plumbing system works silently in the background every day, but small habits that seem harmless can slowly damage it from the inside. Many homeowners don’t realize how daily routines — from how they cook to how they clean — contribute to leaks, clogs, corrosion, and premature pipe failure. By understanding common plumbing mistakes, you can protect your home and avoid expensive repairs.
Why Everyday Habits Create Big Plumbing Problems
Plumbing issues rarely happen overnight. Most start with minor behaviors that gradually wear down pipes, fixtures, and drains. Pouring grease into the sink, flushing wipes, or using the wrong chemical cleaners might not cause immediate damage, but over time these habits become exactly what ruins plumbing systems. Once buildup becomes severe, repairs are no longer small — they turn into clogged sewer lines, damaged fixtures, or burst pipes.
Common Plumbing Mistakes Homeowners Don’t Notice
Many homeowners unintentionally make plumbing mistakes that slowly weaken the system. These errors develop over months or years until warning signs appear — slow drains, gurgling sounds, or recurring clogs. Small oversights, such as ignoring early leaks or allowing low water pressure to continue, can hide bigger internal problems. Because these issues progress quietly, it’s important to recognize them early and correct the routines that cause them.
Kitchen Habits That Damage Plumbing
The kitchen is one of the most high-risk areas for hidden plumbing damage. Certain foods and liquids easily stick to pipe walls, forming thick layers of grease and sludge. Over time, these build-ups restrict water flow and produce foul smells.
Habits that quickly damage kitchen drains:
pouring cooking oil or grease into the sink
washing coffee grounds down the drain
sending fibrous foods like celery, potato peels, or onion skins into the garbage disposal
rinsing sticky sauces or melted fat with only cold water
These are some of the biggest plumbing mistakes to avoid, because even a modern garbage disposal can’t handle materials that harden inside pipes. Grease and starches create stubborn blockages, and once they cool, they solidify into dense masses that professional hydro-jetting is often required to remove.
Bathroom Habits That Quietly Harm Your Pipes
Bathroom plumbing is sensitive to what gets flushed or washed down drains. Even products labeled “flushable” break down too slowly and contribute to sewer clogging. This is one of the plumbing habits to avoid, especially in older houses with narrower drain lines.
Hair is another major problem. When combined with soap residue, it forms a dense, sticky mass that causes slow drainage and eventually full blockages. Long hair strands can wrap around drain components, making the problem worse.
Harsh chemical drain cleaners are another hidden threat. They seem effective at first, but repeated use can corrode metal pipes, break down seals, and damage older PVC. Over time, this leads to leaks behind walls or under sinks — issues far more serious than the original clog.
Laundry & Appliance Mistakes That Lead to Hidden Damage
It’s not only sinks and toilets that suffer from poor habits. Laundry machines, dishwashers, and refrigerators all connect to the plumbing system and can fail if they aren’t used properly.
Overloading your washing machine increases pressure on hoses. Detergent overuse creates residue that builds up in drain lines. Ignoring old or worn hoses is another one of the plumbing mistakes to avoid, as they can burst unexpectedly and flood entire rooms.
Dishwashers can also clog if homeowners treat them as garbage disposals. Food debris, oils, and starches clog internal filters and reduce drainage efficiency. Refrigerator water lines can freeze, kink, or crack if not inspected regularly.
Simple maintenance — checking hoses, cleaning filters, and monitoring drainage — dramatically reduces the risk of appliance-related leaks.
The Worst Plumbing Mistakes That Lead to Costly Repairs
Some of the worst plumbing mistakes create severe, expensive damage. These include flushing non-degradable items, using too much chemical cleaner, or ignoring recurring clogs. Another major issue is leaving small leaks untreated — even slow drips can lead to mold, structural damage, and soaring water bills.
DIY plumbing errors also belong to the biggest risks. Overtightening fittings, using the wrong sealants, or installing mismatched pipe materials can cause failures weeks or months later. Misaligned pipes place pressure on joints, and using incompatible metals can trigger corrosion.
These plumbing errors don’t always show immediate symptoms, which can make the eventual damage far more serious.
How to Avoid Plumbing Issues: Smart Prevention Tips
Good habits protect your plumbing system over the long term. If you want to understand how to avoid plumbing issues, a few consistent behaviors make all the difference. Throw food scraps in the trash instead of the sink. Use drain screens to catch hair. Avoid flushing wipes, cotton pads, and hygiene products. Limit harsh cleaners and choose enzyme-based drain treatments instead.
Regular maintenance, including drain cleaning, leak inspection, and appliance checkups, is essential. Even small improvements in daily habits help prevent clogs, corrosion, and hidden drain damage. By avoiding the things that damage your plumbing system, you extend the life of your pipes and minimize costly repairs.
FAQ

Toronto winters often bring sudden temperature drops that put plumbing systems at risk. When water freezes inside a pipe, it expands and increases pressure, which can lead to cracks or complete pipe bursts once the ice thaws. One of the simplest and most effective ways to reduce this risk is to understand when to drip faucets to prevent frozen pipes and how dripping protects your plumbing.
A slow drip keeps water moving, and moving water is far less likely to freeze. It also relieves pressure inside the pipe, giving the system more stability during long periods of cold weather. While dripping is not the only freeze-prevention method, it is a crucial part of winter plumbing protection for Toronto homes.
Why Dripping Faucets Helps During Freezing Temperatures
Many homeowners wonder whether does letting your faucet drip prevent freezing, especially during harsh cold snaps. In most cases, yes — even a small, steady drip keeps water circulating enough to slow ice formation. It also prevents pressure buildup inside the pipe, reducing the chance of a burst.
This method is especially important for older Toronto homes where plumbing may pass through exterior walls, poorly insulated basements, or areas exposed to drafts.
When You Should Let Faucets Drip
You should drip your faucets when outdoor temperatures fall to –5°C or colder. The risk increases overnight when heating cycles less frequently and pipes cool faster. Dripping is especially important if your home has a history of frozen pipes, plumbing that runs through cold areas, or fixtures installed on exterior walls.
Many people ask should you drip faucets in cold weather even when only one part of the house feels cold. The answer is yes — if a single area is significantly cooler, its pipes are at higher risk of freezing.
Which Faucets Are Most Important to Drip
Not all faucets need to drip — focus on the most vulnerable areas of your home.
Critical faucets to drip during freezing weather:
which are located on the external walls
kitchen or bathroom sinks above uninsulated spaces
lines running through basements, crawl spaces, or cold utility rooms
farthest from the main water line (keeps water moving through the entire system)
Homeowners also ask whether should you drip hot water faucets in cold weather. The truth is yes — hot water lines can freeze just as easily once the water cools inside the pipe.
Outdoor Faucets and Freeze Prevention
Exterior water outlets freeze faster than any indoor fixture. If your outdoor tap is connected to an active supply line, consider the question should you drip outside faucets during a freeze. If the line is still active, dripping can help prevent ice formation.
Before cold weather hits, disconnect hoses and remove attachments so water can drain properly. In spring, many homeowners search how to stop an outside faucet from dripping — usually the issue is a worn washer or loose packing nut, which can be repaired once freezing weather is over.
How to Keep a Faucet From Freezing
Dripping is helpful, but preventing frozen pipes requires additional precautions.
Additional ways to protect your plumbing:
keep cabinet doors open to allow warm air around pipes • insulate exposed or exterior-wall plumbing • maintain stable indoor temperatures • seal drafts around windows, doors, and foundation gaps • use heat tape for high-risk pipe sections
These measures work together with dripping to reduce the chances of frozen pipes.
Should You Leave Faucets Dripping While Away
If you leave home during extreme cold, letting faucets drip is strongly recommended. This aligns with the idea of when leaving water dripping to prevent freezing pipes, ensuring pipes stay moving even when nobody is home to monitor the system. Keep your home heated to at least 16°C and double-check vulnerable pipes before leaving.
When Dripping Isn’t Enough
If your pipe is already frozen, dripping will not solve the problem. Signs include reduced flow, no water at all, frost on the pipe, or strange noises. In this case, leave the faucet open and warm the area gently. Avoid using open flames or high-heat tools. If the pipe appears damaged, call a professional immediately to avoid further issues.
FAQ
Does dripping faucets really help prevent freezing?
Yes — a slow drip keeps water moving and helps relieve internal pressure.
How long should faucets drip after temperatures rise?
Once temperatures stay above freezing for 24 hours, it’s safe to stop dripping.
Can hot water lines freeze too?
Yes. Hot water lines cool quickly in freezing weather and should also drip during extreme cold.
Do outdoor faucets always need to drip?
Only if the supply line is still active. Winterized faucets do not need dripping.
What’s the best faucet to drip if I can only drip one?
Use the faucet farthest from the main water entry point — it helps circulate water through the longest section of the system.
Polybutylene plumbing—often referred to as Poly-B—was widely installed in homes between the late 1970s and mid-1990s. At the time, it was marketed as an affordable, flexible, and long-lasting alternative to copper. Decades later, homeowners discovered a different reality: this material ages poorly, reacts to water chemistry, and fails far more frequently than expected.
If your home was built or renovated during this period, there is a chance that this type of piping may still be hidden behind walls or under floors. Understanding the signs of Poly-B pipes, the dangers associated with them, and how to identify Poly-B plumbing can help you avoid water damage and costly emergency repairs.
What These Pipes Are and Why They Were Used
This gray plastic piping became popular because it was cheap, flexible, and quick to install. Builders appreciated the ease of working with it, and homeowners enjoyed lower construction costs. Unfortunately, it did not perform well long term.
Exposure to chlorine, UV light, high water pressure, and poor installation practices caused many systems to degrade. Today, the material is known for its unreliability and frequent failures.
Before considering replacement, you first need to understand what Poly-B pipes look like and how to determine whether they are part of your home’s plumbing.
How to Identify Poly-B Piping in Your Home
Here are the simplest ways to determine whether this type of plumbing is installed in your home:
1. Look for the Distinctive Grey Color
These pipes are usually light gray—sometimes slightly bluish.
2. Check for Markings or Stamps
Common labels include:
PB or PB2110
Manufacturer names like Ipex, Vanguard, Bow, Centurion
Tankless or “on-demand” water heaters are becoming increasingly popular among homeowners seeking energy-efficient and space-saving solutions. Unlike traditional systems with large storage tanks, tankless models heat water only when it’s needed — providing a continuous flow of hot water without wasting energy.
But before you invest, it’s important to understand the real pros and cons of tankless water heaters and how they compare to conventional models.
How Tankless Water Heaters Work
A tankless water heater uses either gas burners or electric elements to heat water instantly as it passes through the system. When you turn on a tap, cold water flows through a heat exchanger and comes out hot on demand. Since there’s no storage tank, the system doesn’t lose heat through standby energy loss — one of the main reasons these units are considered more efficient than traditional models.
Still, tankless systems have specific installation and maintenance requirements that every homeowner should consider.
Advantages of Tankless Water Heaters
1. Endless Hot Water
One of the biggest benefits of tankless water heaters is that they never run out of hot water. Whether you’re taking long showers or running multiple loads of laundry, the heater keeps producing hot water continuously, as long as your system capacity matches your household’s demand.
2. High Energy Efficiency
Tankless units are designed to work only when you need hot water. Unlike tank-style heaters that maintain a full reservoir of hot water 24/7, a tankless system activates only when the tap is turned on. This can reduce energy consumption by up to 30% compared to traditional models — a major advantage for energy-conscious homeowners.
3. Space-Saving Design
Since there’s no large tank to store, a tankless model can be wall-mounted in compact spaces such as closets or utility rooms. For small homes, condos, or apartments, this space-saving benefit makes tankless water heaters an attractive option.
4. Longer Lifespan
A high-quality tankless hot water heater can last up to 20 years with proper maintenance — almost double the lifespan of a conventional storage-tank heater. This longevity helps offset the higher initial investment, offering greater long-term value.
5. Lower Risk of Water Damage
Traditional tanks can sometimes rust or crack, causing leaks and costly water damage. With no storage tank, the risk of major flooding or corrosion is significantly reduced — another practical advantage of tankless water heaters.
Disadvantages of Tankless Water Heaters
1. Higher Initial Cost
The main downside of tankless water heaters is the upfront expense. Both the unit itself and its professional installation typically cost more than a conventional heater. Homes may require additional gas line or electrical upgrades, increasing the total cost.
2. Limited Flow for Multiple Outlets
While a tankless heater provides endless hot water, it can struggle when several appliances run simultaneously. For instance, using two showers and a washing machine at once might cause a noticeable drop in water temperature or pressure. Larger households often need multiple units to handle peak demand effectively.
3. Professional Installation Required
Installing a tankless water heater is more complex than replacing a traditional tank. Incorrect setup can lead to poor performance or safety hazards. It’s best to have certified plumbers — such as POM Plumbing — handle installation, ensuring your system operates efficiently and meets all local codes.
4. Slight Delay in Hot Water Delivery
Because the system heats water on demand, there can be a short delay before hot water reaches the tap. Although it’s usually only a few seconds, this delay can lead to slightly higher water use over time.
5. Maintenance Needs
Tankless water heaters require regular descaling to prevent mineral buildup, especially in areas with hard water. Failing to flush the unit annually may lead to reduced efficiency and shorter lifespan. This maintenance requirement is one of the common cons of tankless water heaters that homeowners should be aware of.
Tankless vs. Traditional Water Heaters
Compared to traditional tank systems, tankless water heaters are more energy-efficient, compact, and durable. However, they come at a higher initial cost and may not meet heavy, multi-outlet demand without upgrades.
Traditional tank heaters are cheaper to install and can supply multiple fixtures simultaneously, but they take up more space, waste energy through heat loss, and require replacement more frequently.
In short, if your priority is efficiency, longevity, and unlimited hot water, a tankless model is a smart long-term investment. If you’re looking for affordability and simplicity, a traditional tank might still fit your needs.
Are Tankless Water Heaters Worth It?
For many homeowners, the pros of tankless water heaters — including energy savings, compact design, and endless hot water — outweigh the disadvantages. However, if you have a large household or limited installation budget, the cons such as cost and flow limitations may be important considerations.
Before making a final decision, it’s best to consult with professionals like POM Plumbing, who can assess your water usage, recommend the right size, and install your new heater safely and efficiently.
Final Thoughts
Tankless water heaters represent a modern, eco-friendly upgrade for homeowners tired of running out of hot water or wasting energy. While they do have installation and maintenance challenges, their performance, efficiency, and durability make them a worthy investment for most homes.

Frequently Asked Questions
How long does a tankless water heater usually last?
A quality tankless water heater can last around 20 years or more with regular maintenance. This is nearly twice the lifespan of most traditional tank-style heaters. Flushing the system annually and using a water softener in areas with hard water can significantly extend its service life.
Do tankless water heaters work during a power outage?
Electric tankless water heaters require electricity to operate, so they won’t function during an outage. Gas-powered models may still need electricity for ignition and control systems. If power reliability is a concern, consider installing a small backup generator or battery system.
Can I replace my traditional water heater with a tankless system easily?
In most cases, switching to a tankless water heater requires professional modification to your home’s plumbing, venting, or gas lines. Because of the higher heating capacity, proper installation is essential for safety and performance. Certified plumbers like POM Plumbing can evaluate your setup and handle the conversion smoothly.
How often do tankless water heaters need maintenance?
Maintenance should be done at least once a year. The process includes flushing mineral deposits, cleaning filters, and checking burners or electrical components. Regular service prevents scale buildup and ensures your system maintains optimal efficiency and water pressure.
Are tankless water heaters suitable for large families?
Yes, but only if properly sized. Large households may need either a high-capacity tankless unit or multiple systems working in parallel. A professional plumber can calculate your peak water demand and recommend the right setup to ensure a steady hot water supply for everyone.
What type of water heater is best — gas or electric tankless?
Both have advantages. Gas tankless water heaters heat water faster and handle higher flow rates, making them ideal for large homes. Electric models are easier to install, more compact, and require less maintenance but may struggle with multiple fixtures in use. Your home’s infrastructure and energy costs often determine the best option.
Do tankless water heaters increase home value?
Yes. Many homebuyers see tankless systems as a modern, energy-efficient upgrade. They can slightly raise property value and make your home more appealing on the market, especially if paired with other eco-friendly improvements.
