There’s nothing quite as unpleasant—or alarming—as the smell of sewer gas in your home. It’s more than just a bad odor; it could be a sign of a serious issue within your plumbing or drainage system. While many homeowners might try to mask the smell with air fresheners or cleaning products, the root cause needs professional attention.

In this article, we’ll break down what causes sewer gas odors in your home, the risks they pose, and what you can do to eliminate them for good.

What Is Sewer Gas?

Sewer gas is a mixture of gases produced by the breakdown of organic waste in sewer systems. The main components include:

• Hydrogen sulfide (the one that smells like rotten eggs)
• Methane
• Ammonia
• Carbon dioxide
• Nitrogen

In small amounts, sewer gas isn’t typically life-threatening. However, prolonged exposure can be hazardous to your health and indicate a malfunctioning plumbing system that could lead to water damage, mold, or even structural issues.

Common Causes of Sewer Gas Odors in Homes

1. Dry Plumbing Traps

One of the most common causes of sewer gas odors in your home is a dry P-trap. A P-trap is the curved section of pipe located beneath sinks, tubs, and floor drains. It holds a small amount of water that acts as a barrier to prevent sewer gas from coming back up through the drain.

If the fixture hasn’t been used in a while—like in a guest bathroom or basement floor drain—the water in the trap can evaporate, allowing foul odors to enter your living space.

Solution: Run water down unused drains every few weeks to keep the trap filled.

2. Broken or Cracked Sewer Pipes

If there’s a crack or break in your home’s sewer lines—especially those hidden behind walls or under the foundation—sewer gas can seep into your home through the opening. This issue can also lead to sewage backups and structural damage if not addressed promptly.

Solution: A plumber can perform a smoke test or video camera inspection to identify the exact location of the break and recommend proper repairs.

3. Blocked or Clogged Vents

Your home’s plumbing system includes a network of vent pipes that allow sewer gases to escape outdoors. If these vents become blocked (due to debris, bird nests, ice, or snow), gases can’t exit properly and may be pushed back into your home.

Solution: A licensed plumber can clear the blocked vent stack and restore airflow through the system.

4. Loose or Damaged Toilet Seals

Another common source of sewer gas smells is the wax ring seal beneath the toilet. If this seal is broken, loose, or improperly installed, sewer gases can leak into the bathroom—especially when you flush.

You may also notice the toilet rocks slightly or small water leaks at the base, both of which indicate a problem with the seal.

Solution: Reseating or replacing the wax ring can eliminate the odor and restore a proper seal.

5. Sewer Line Backups

If your main sewer line is partially or fully blocked, it can cause wastewater to back up into the home and release sewer gas odors. Early signs include slow drains, gurgling noises, or multiple drains clogging at the same time.

Solution: A professional plumber can inspect the sewer line and perform drain cleaning or hydro jetting if necessary.

6. Improperly Installed or Damaged Plumbing Fixtures

Sometimes the issue lies in poor installation. If plumbing vents are missing or improperly connected, or if there are loose joints in the drainpipes, sewer gas can find its way into your home.

This is more common in older homes or DIY renovations where plumbing was not done to code.

Solution: Have a licensed plumber inspect your system to identify any non-code-compliant connections.

Health Risks of Sewer Gas Exposure

While the smell alone is unpleasant, prolonged exposure to sewer gas can also pose health risks, especially in high concentrations. These include:

• Headaches
• Nausea
• Dizziness
• Eye and throat irritation
• Respiratory problems
• Fatigue

Hydrogen sulfide, even in low levels, can be irritating. In higher levels, it can be toxic. Methane is flammable and presents a fire or explosion risk if it accumulates indoors. This makes it critical to investigate any recurring or unexplained sewer odors as soon as possible.

When to Call a Professional Plumber

If you notice persistent sewer gas odors in your home, especially around sinks, showers, toilets, or floor drains, don’t ignore them. While some problems, like a dry trap, are easy to fix, others may require professional diagnosis and repair.

You should call a licensed plumber if:

• The smell is constant or recurring
• Multiple fixtures emit the odor
• You hear gurgling sounds from drains
• There are signs of water damage near toilets or sinks
• You feel ill when the smell is present
• You suspect a broken pipe or sewer line leak

At POM Plumbing, we use advanced tools like smoke testing, video inspections, and moisture sensors to quickly locate the source of the odor and resolve the issue permanently.

How to Prevent Sewer Gas Smells in the Future

Once the problem is fixed, take steps to prevent sewer gas from coming back:

• Run water in all drains weekly to keep P-traps filled
• Keep toilets flushed in rarely used bathrooms
• Schedule annual plumbing inspections
• Don’t ignore slow or gurgling drains—act early
• Seal and vent new plumbing fixtures properly
• Use drain strainers to avoid clogs and debris buildup

Maintaining your plumbing system is the best defense against sewer odors and the damage they can cause over time.

Final Thoughts

Sewer gas odors in your home are more than just a nuisance—they’re a red flag that something isn’t working as it should in your plumbing system. From dry traps to broken pipes and blocked vents, there are several reasons sewer gas might be entering your space. But with professional help and preventive care, you can eliminate the odor and protect your home and health.

Most homeowners use water every single day without thinking about what’s actually flowing through their pipes. But understanding the difference between hard and soft water can have a major impact on how your plumbing system performs—and how much you spend on maintenance and repairs.

So, what is the difference between hard and soft water? In simple terms, hard water contains high levels of dissolved minerals, especially calcium and magnesium. Soft water, by contrast, has been treated to remove those minerals. While both types of water are safe to use, the difference between soft and hard water can dramatically affect your plumbing fixtures, appliances, and daily comfort.

What Is the Difference Between Hard and Soft Water?

Hard water is water that contains elevated levels of calcium and magnesium. These minerals are naturally absorbed as groundwater passes through limestone and chalk deposits. The harder the water, the higher the mineral concentration.

Soft water, on the other hand, is water that has been processed to remove these minerals, usually through a water softener that replaces calcium and magnesium with sodium or potassium ions.

So, the key difference between hard water and soft water is their mineral content. Hard water is mineral-rich, while soft water is mineral-reduced. This simple difference has a significant impact on plumbing and household performance.

How to Know If You Have Hard Water

Many people ask, “What is the difference between soft and hard water in daily life?” You might already be experiencing the signs of hard water without realizing it. Common symptoms include:

• Soap that doesn’t lather well
• White or chalky residue on faucets and fixtures
• Water spots on dishes and glassware
• Clothes that feel stiff or look faded after washing
• Dry skin and hair after bathing
• Low water pressure due to internal scale buildup

If these issues sound familiar, there’s a good chance you have hard water in your home.

How Hard Water Affects Your Plumbing

One of the most important aspects of understanding the difference between hard and soft water is knowing how hard water can damage plumbing over time. Here’s how:

Mineral Buildup in Pipes

As hard water flows through your plumbing, calcium and magnesium begin to accumulate inside the pipes. Over time, this buildup—called limescale—narrows the diameter of the pipes, restricting water flow. This leads to reduced water pressure, increased strain on your plumbing, and eventually, complete clogs.

Damage to Water Heaters

Water heaters are particularly vulnerable to hard water. The heat causes minerals to separate from the water and settle at the bottom of the tank. This sediment layer forces the heater to work harder, reducing efficiency and increasing your energy bills. If ignored, it can lead to overheating, failure, or even bursting of the tank.

Wear on Appliances and Fixtures

Hard water doesn’t just affect pipes—it also reduces the lifespan of dishwashers, washing machines, coffee makers, and other appliances. Mineral deposits can clog valves, coat heating elements, and reduce functionality. Faucets, showerheads, and toilets can also suffer from visible scaling, requiring more frequent replacement.

How Soft Water Benefits Your Plumbing System

Now that you know the difference between hard water and soft water, it’s easy to see why soft water is generally better for plumbing. Soft water reduces or eliminates scale buildup, allowing water to flow freely through your pipes. This helps maintain consistent water pressure and improves the efficiency of your entire plumbing system.

Soft water also extends the lifespan of water heaters, dishwashers, and washing machines. With fewer minerals present, components inside these devices stay cleaner and last longer. You’ll also notice that soap and shampoo lather more easily, your clothes feel softer, and cleaning your bathroom becomes much easier—because there’s no stubborn scale to scrub.

Understanding what prevents damage in plumbing starts with understanding the difference between soft and hard water—and switching to soft water can make a noticeable difference in both plumbing performance and maintenance costs.

What Prevents Plumbing Damage from Hard Water?

If you’re wondering what prevents corrosion or mineral buildup in pipes, the answer often lies in installing a water softener. A water softening system removes calcium and magnesium before the water reaches your home’s internal plumbing.

Other steps that can help include:

• Regular descaling of appliances and fixtures
• Installing filters or conditioners at the main water line
• Using vinegar-based cleaners to dissolve surface limescale
• Scheduling routine plumbing inspections to detect early damage

Knowing how to prevent mineral buildup is just as important as knowing the difference between soft and hard water. Prevention today can help you avoid expensive plumbing repairs tomorrow.

What Is the Difference Between Soft Water and Hard Water for Your Lifestyle?

The difference between hard and soft water isn’t just about plumbing—it affects how your home functions day to day. For instance:

• Soap and detergent work better with soft water, so you’ll use less and save money.
• Clothes retain their color and texture longer when washed in soft water.
• Skin and hair feel smoother, since soap rinses off more completely.
• Appliances last longer and run more efficiently.
• Bathrooms and kitchens are easier to keep clean, with less visible buildup on surfaces.

In short, understanding what is the difference between hard and soft water can improve your comfort and reduce your household expenses over time.

Should You Invest in a Water Softener?

If your home has hard water, a water softener is often the best long-term solution. It not only protects your plumbing and appliances but also enhances your quality of life in dozens of small, daily ways.

If you’re unsure about your water’s hardness level, a plumber can test your water and offer personalized recommendations. In areas like Toronto and the GTA, where mineral levels vary widely by neighborhood, having a professional assess your system can be a wise first step.

Final Thoughts

So, what is the difference between hard and soft water? In simple terms, it’s about minerals—and those minerals can make a big difference in your plumbing system. Hard water leads to scale, corrosion, and early appliance failure. Soft water helps preserve your pipes, reduce energy costs, and improve your everyday experience.

If you’re seeing signs of hard water damage or want to prevent future plumbing issues, now is the time to act.

Whether you’re dealing with a leaky faucet, planning a bathroom renovation, or facing a plumbing emergency, choosing the right plumbing contractor can make all the difference. A qualified, experienced, and reliable plumber ensures your project is completed efficiently, safely, and in compliance with local building codes. On the other hand, hiring the wrong contractor can lead to delays, damage, and costly repairs down the road.

In this guide, we’ll explore the most important factors to consider when hiring a plumbing contractor in Toronto or the surrounding area. From licensing and insurance to pricing, reviews, and guarantees, these tips will help you make a confident and informed decision.

1. Licensing and Certification

First and foremost, ensure the plumbing contractor is fully licensed to operate in your region. In Ontario, plumbers must be certified by the Ontario College of Trades and carry a valid Certificate of Qualification.

Hiring a licensed plumbing contractor means:

• They’ve completed proper training and apprenticeship
• They understand local building codes and safety regulations
• Their work is subject to inspections and professional standards

You can ask for a license number or verify credentials online through provincial or municipal directories. Don’t take a contractor’s word for it—check their certification before signing a contract.

2. Proof of Insurance

A reputable plumbing contractor should have both liability insurance and WSIB (Workplace Safety and Insurance Board) coverage for their employees. Insurance protects both you and the contractor in case of:

• Accidental damage to your property
• Injuries on the job site
• Legal or financial disputes

If a plumber lacks insurance and something goes wrong, you could be held financially responsible. Always request proof of insurance before hiring any contractor.

3. Experience and Specialization

Not all plumbing contractors offer the same level of experience or skill. Some specialize in new home construction, while others focus on renovations or emergency repairs. Before hiring a plumber, ask:

• How many years have they been in business?
• Do they have experience with your specific type of project?
• Can they provide examples of similar work?

For example, if you’re planning a full bathroom renovation, you’ll want a contractor who understands fixture relocation, waterproofing, and drainage upgrades—not just someone who handles minor repairs.

4. Transparent Pricing and Written Estimates

Clear and honest pricing is one of the most important aspects of a good plumbing contractor. Ask for a detailed written estimate that includes:

• Labour costs
• Materials and parts
• Project timeline
• Potential extra charges (e.g., emergency fees, permits)

Avoid vague quotes or contractors who won’t put things in writing. Also, be cautious of bids that are significantly lower than others—you might end up paying more later due to poor workmanship or hidden costs.

5. Customer Reviews and Testimonials

One of the best ways to gauge a plumber’s reliability is by reading online reviews or asking for client references. Check trusted platforms such as:

• Google Reviews
• HomeStars
• Yelp
• Better Business Bureau (BBB)

Look for comments about punctuality, professionalism, communication, and overall satisfaction. A consistent history of positive feedback is a good sign of a trustworthy plumbing contractor.

6. Availability and Responsiveness

Plumbing issues don’t always occur during business hours. That’s why it’s important to hire a contractor who offers flexible scheduling and can handle emergency service calls, especially in critical situations like:

• Burst pipes
• Sewer backups
• No hot water
• Flooded basements

Ask how quickly they can respond to emergencies and whether they offer same-day or 24/7 service. A responsive contractor shows they value customer care and are prepared for urgent repairs.

7. Guarantees and Warranties

Reliable plumbing contractors should stand behind their work with written warranties. Ask if they offer guarantees for:

• Workmanship
• Replacement parts or fixtures
• Leak protection or future issues

A strong warranty gives you peace of mind and shows that the contractor is confident in the quality of their service.

8. Communication and Professionalism

When hiring a plumbing contractor, pay attention to how they communicate during your initial interactions. Are they respectful, responsive, and willing to answer your questions? Do they explain your options clearly and make recommendations based on your budget and goals?

Good contractors don’t just fix pipes—they build trust and relationships with their clients. Clear communication helps prevent misunderstandings and ensures that the work gets done right the first time.

9. Local Knowledge and Code Compliance

Hiring a local contractor means they are familiar with municipal regulations, permitting requirements, and building codes in your area. This is especially important in cities like Toronto, where plumbing systems must comply with Ontario Plumbing Code and city-specific bylaws.

A local contractor will also know the typical challenges of older homes, seasonal weather impacts, and common materials used in local construction.

10. Ask Questions Before Signing a Contract

Before you commit, don’t hesitate to ask important questions like:

• Who will be performing the work—licensed staff or subcontractors?
• What is the estimated project timeline?
• Are permits required, and who obtains them?
• How will changes or additional costs be handled?
• Do you clean up after the job is completed?

A professional plumbing contractor should answer these questions without hesitation and be willing to provide documentation for everything discussed.

Pipe corrosion is one of the most common—and costly—problems homeowners face in maintaining their plumbing systems. Whether it’s copper, galvanized steel, or even brass, every metal pipe is vulnerable to the slow and damaging effects of corrosion. But the good news is: with proper care and early intervention, corrosion can often be prevented or at least significantly delayed.

In this guide, we’ll cover the top expert tips on how to prevent corrosion in pipes, with a special focus on preventing copper pipe corrosion—since copper remains one of the most widely used materials in residential plumbing systems. We’ll also look at the signs of pipe corrosion, why it happens, and what you can do today to protect your home’s water supply system.

Why Pipe Corrosion Happens

Before learning how to prevent pipe corrosion, it’s important to understand what causes it in the first place. Corrosion is a natural chemical process that occurs when water reacts with the metal surface of a pipe. Over time, this reaction can lead to rust, leaks, mineral buildup, and structural weakening.

Common causes include:

• Low or unbalanced pH in water (acidic or highly alkaline water)
• High oxygen or chlorine levels in municipal water supply
• Electrolysis or galvanic corrosion (from connecting dissimilar metals)
• Stagnant water in unused pipes
• High water velocity causing abrasion in the inner pipe surface
• Sediment or bacteria buildup inside plumbing lines

If left untreated, corrosion can cause discoloration in your water, low pressure, foul odor, pinhole leaks, or even full pipe failure.

How to Prevent Corrosion in Pipes: Proven Tips

1. Monitor and Adjust Water pH Levels

One of the biggest factors in preventing copper pipe corrosion is water chemistry. Ideally, your home’s water should have a neutral pH between 6.5 and 8.5.

• If the pH is too low (acidic), it can eat away at copper and steel pipes.
• If it’s too high (alkaline), it can cause mineral deposits that increase internal pressure.

Have your water tested annually and consider using a neutralizing filter or pH balancing system if needed.

2. Install Dielectric Unions

When dissimilar metals like copper and galvanized steel are connected, galvanic corrosion can occur. This reaction causes one metal (usually the less noble one) to corrode faster.

To prevent corrosion in copper pipes connected to other metals, install dielectric unions—fittings that separate the metals and prevent electrical current transfer.

3. Control Water Velocity

High water pressure or flow rates can lead to erosion corrosion, especially in copper systems. To avoid this:

• Keep residential water pressure between 40–60 psi.
• Use properly sized pipes to prevent excessive velocity.
• Avoid sharp bends and elbows that increase turbulence.

If your pipes “bang” or “whistle,” it may be a sign that flow rates are too high.

4. Flush Pipes Regularly in Low-Use Areas

Water stagnation contributes to corrosion by allowing oxygen and minerals to settle inside the pipe. To prevent corrosion in pipes in guest bathrooms, seasonal properties, or unused lines, flush them regularly to keep water moving.

You can do this by running taps weekly or installing an automated system to cycle water through the lines.

5. Avoid Over-Chlorination

While chlorine helps disinfect municipal water, high levels can be corrosive to copper and other metals. If you’re concerned about how to prevent copper pipe corrosion due to chlorine:

• Test your water for chlorine concentration.
• Install carbon filters or dechlorinating systems if necessary.

These systems can protect both your plumbing and your health.

Preventing Copper Pipe Corrosion in New Installations

If you’re installing a new plumbing system or replacing old pipes, taking preventive steps from day one will help extend the life of your pipes:

• Use only certified, high-quality copper piping (Type L or Type K for durability).
• Choose plastic or brass fittings when possible to minimize galvanic risk.
• Make sure all joints are clean and properly soldered—poor soldering leads to weak points.
• Consider coating exposed pipes with a protective insulation or sealant.

What Prevents Corrosion in Pipes Long-Term?

Preventing copper pipe corrosion is not about a one-time fix—it’s about ongoing maintenance and monitoring. Here’s what you can do to protect your pipes over the long term:

• Install a water softener if you live in a hard water area to reduce scale buildup.
• Use corrosion inhibitors in closed-loop systems like radiant heating or boilers.
• Inspect visible piping annually for green stains, pinhole leaks, or mineral buildup.
• Keep your water heater well-maintained—a failing anode rod can accelerate corrosion.
• Get professional plumbing inspections to detect early warning signs.

Homeowners often ask what prevents corrosion in pipes best—and the answer is a combination of water quality control, smart installation practices, and regular system checkups.

Discovering mold near your plumbing fixtures can be both frustrating and alarming. Mold isn’t just an eyesore—it can signal hidden plumbing issues and lead to serious health risks if left untreated. Whether you find it around your bathroom sink, under the kitchen faucet, or near your shower valve, knowing what to do when you see mold near plumbing fixtures is crucial for protecting your home and family.

In this article, we’ll walk you through why mold forms around plumbing, what immediate steps you should take, and how to address both the symptoms and the root cause. We’ll also explore when it’s time to call a professional plumber or mold remediation expert.

Why Mold Forms Near Plumbing Fixtures

Mold thrives in damp, dark, and poorly ventilated environments—making areas around plumbing fixtures a prime target. Common causes of mold near sinks, showers, and toilets include:

• Slow or hidden leaks in pipes, seals, or joints
• Condensation buildup on cold water pipes
• Poor ventilation in bathrooms or kitchens
• Standing water or constant moisture around fixtures
• Broken caulking or cracked tile grout

Even a small, slow drip behind your wall or beneath your vanity can create the perfect breeding ground for mold over time. That’s why early detection and proper response are key.

Is Mold Dangerous?

Yes—some types of household mold can pose serious health risks, especially to individuals with allergies, asthma, or weakened immune systems. Black mold (Stachybotrys chartarum) is particularly notorious, but even common types like Aspergillus or Cladosporium can cause symptoms such as:

• Coughing, sneezing, or wheezing
• Skin rashes
• Eye or throat irritation
• Headaches or fatigue
• Worsening asthma symptoms

The longer mold remains undisturbed, the more spores it can release into your indoor air—affecting the health of your entire household.

Step-by-Step: What to Do If You Find Mold Near Plumbing Fixtures

If you’ve noticed dark patches, musty smells, or visible mold growth near your plumbing, follow these steps:

1. Don’t Disturb It Immediately

Avoid scrubbing or wiping the mold without proper protection. Disturbing mold without containing it can release spores into the air, increasing your exposure and spreading contamination.

2. Inspect for Moisture or Leaks

Look carefully around the fixture for signs of leaking:

• Wet caulking
• Water stains on nearby walls
• Pooled water under cabinets
• Rust on pipe connections
• Bubbling or peeling paint

If there’s an active leak, shut off the water supply to that fixture and dry the area as much as possible.

3. Ventilate the Space

Open windows or turn on exhaust fans to reduce humidity. Mold cannot grow without moisture, so improving airflow and lowering humidity levels can slow its spread.

4. Wear Protective Gear

If you plan to clean minor mold growth yourself, wear gloves, goggles, and an N95 respirator mask. Never clean mold with bare hands or without respiratory protection.

5. Clean with Safe Solutions

For small, surface-level patches of mold (less than 1 sq. meter), you can use:

• A mixture of white vinegar and water (no rinse needed)
• Hydrogen peroxide (3%) spray
• Baking soda mixed with warm water

Avoid using bleach on porous surfaces like drywall—it may worsen the problem by only killing surface mold and pushing moisture deeper.

6. Remove Damaged Materials

If the mold has penetrated drywall, insulation, baseboards, or wood framing, those materials may need to be removed and replaced. Porous materials that remain damp will continue to feed mold growth.

When to Call a Professional

While small mold patches might be manageable as a DIY project, larger infestations require professional intervention. You should call a licensed plumber and mold remediation expert if:

• The mold covers more than 1 square meter
• You smell musty odors but don’t see visible mold
• There are signs of ongoing leaks or water damage
• Mold is growing behind walls, under floors, or inside cabinets
• You or a family member are experiencing health symptoms

A professional plumber can detect and fix hidden leaks, replace faulty pipes, or re-seal failing fixtures. At the same time, mold remediation teams can safely remove and treat contaminated areas using specialized equipment like HEPA filters and air scrubbers.

Preventing Mold in the Future

Once you’ve dealt with existing mold, it’s important to prevent it from coming back. Here’s how:

• Regularly inspect plumbing fixtures and under-sink cabinets for signs of moisture
• Use high-quality caulking around tubs, sinks, and showers
• Ensure bathrooms and kitchens have proper exhaust ventilation
• Install moisture detectors or leak alarms in problem-prone areas
• Fix leaks immediately and keep humidity below 50%

If you live in Toronto or the GTA, seasonal humidity and older plumbing systems can increase the risk of mold. That’s why many homeowners schedule regular plumbing inspections to catch issues early.

When it comes to installing or replacing a plumbing system, choosing the right materials is critical. With many different types of water pipes available on the market, homeowners are often faced with the question: which one is best for my property? In this guide, we’ll explore the most popular options — copper, PVC, and PEX — and help you understand how these different types of pipes for water supply compare in terms of durability, performance, and cost.

Why Does Pipe Selection Matter?

Water pipes form the core of any home’s plumbing infrastructure. They carry fresh water to your taps, showers, toilets, and appliances. Choosing the wrong pipe material can result in leaks, poor water quality, frequent repairs, and reduced efficiency. That’s why understanding the different types of pipes used for water supply is essential, whether you’re building a new home or upgrading an outdated system.

What Are the Different Types of Water Pipes?

Modern plumbing primarily relies on three types of water pipes: copper, PVC (polyvinyl chloride), and PEX (cross-linked polyethylene). Each has unique advantages and disadvantages depending on the use case.

Let’s take a closer look at these different types of pipes used in water supply systems.

Copper Pipes: Traditional and Trusted

Copper pipes have been used in plumbing for decades and are still a preferred option for many professionals. They are known for their strength, longevity, and resistance to high temperatures.

One of the biggest advantages of copper is its reliability over time. It doesn’t leach chemicals into your drinking water, and it can last 50 years or more if properly installed. That said, copper is one of the most expensive materials on the market, both in terms of raw cost and installation.

Copper pipes are ideal if you want a long-term solution and are willing to invest more upfront. They’re especially useful in homes where high water pressure or temperature is a factor. However, they require soldering during installation and are less flexible than other options.

PVC Pipes: Lightweight and Cost-Effective

Among the different types of water supply pipes, PVC is one of the most popular for cold water applications. It’s inexpensive, easy to cut, and doesn’t corrode over time. PVC pipes are made from a plastic compound that resists chemical damage and internal scaling, making them ideal for transporting potable water in low-pressure systems.

The main drawback of PVC is its limited temperature tolerance. It’s not suitable for hot water lines because it softens and deforms under heat. In addition, exposure to direct sunlight can degrade the material, making it unsuitable for outdoor or above-ground installations.

PVC pipes are best suited for cold water distribution, irrigation, and drainage systems. For budget-conscious homeowners, they’re a solid choice — especially in regions where freezing is not a major concern.

PEX Pipes: The Flexible Modern Standard

PEX piping has become extremely popular in recent years. It’s flexible, affordable, and easy to install, even in tight or awkward spaces. PEX is one of the most adaptable different types of pipes for water supply, and its flexibility allows it to curve around corners without the need for additional fittings.

PEX is resistant to scale and chlorine, and it performs well under both hot and cold temperatures. Its biggest selling point is how quickly and efficiently it can be installed — often reducing labor costs significantly.

Despite its benefits, PEX should not be used outdoors as it degrades when exposed to UV light. Also, since it’s a newer material compared to copper or PVC, some professionals remain cautious about its long-term durability, though modern PEX systems are designed to last 40–50 years.

If you’re renovating your home or replacing old plumbing, PEX offers a reliable, cost-effective alternative to traditional pipework.

Understanding the Differences Between Pipe Types

If you’re asking, “what are the different types of water pipes and which one should I choose?” — the answer depends on your specific plumbing needs.

Copper pipes are the premium choice for long-term performance and water safety, especially in homes where reliability is a priority. PVC is a lightweight and affordable solution for cold water lines, ideal for budget-conscious projects. PEX offers a modern, versatile solution that’s easy to work with and suited for most residential applications.

Each of these materials addresses different priorities — from installation cost to heat tolerance — and that’s why there are multiple different types of pipe for water supply in use today.

Other Pipe Types to Be Aware Of

While copper, PVC, and PEX are the most commonly used types of pipes for water, other materials are sometimes used in specific applications:

• Galvanized steel pipes were once standard but are now outdated due to rust and corrosion issues.
• CPVC is similar to PVC but can handle hot water; however, it’s more brittle and prone to cracking.
• HDPE is often used in municipal or industrial systems but is less common in residential plumbing.

Knowing the full range of different types of water pipe materials can help you make informed decisions, especially when dealing with specialized needs.

Local Considerations and Building Codes

A well-maintained septic tank is essential for the proper functioning of your home’s wastewater system. Regular maintenance not only extends the lifespan of your system but also helps prevent costly repairs and environmental hazards. Here are some key tips on how to properly maintain your septic tank.

1. Schedule Regular Inspections and Pumping

Septic tanks should be inspected by a professional every 1-3 years and pumped as needed, usually every 3-5 years. The frequency depends on several factors:

• Household size – More people generate more wastewater, increasing the need for frequent pumping.
• Tank size – A smaller tank fills up faster and may require more frequent maintenance.
• Water usage – High water consumption can overload the system, leading to inefficiencies.
• Solid waste accumulation – The more non-biodegradable waste that enters the system, the quicker it fills up.

A professional can check for signs of wear, leaks, and other issues that may require repairs.

2. Be Mindful of Water Usage

Excessive water use can overwhelm your septic system, causing premature failure. To reduce strain on your system:

• Fix leaks immediately – A dripping faucet or running toilet can waste gallons of water daily.
• Install water-efficient appliances – Low-flow toilets, showerheads, and washing machines can significantly reduce water usage.
• Spread out water usage – Instead of doing multiple loads of laundry in one day, spread them out throughout the week.
• Avoid long showers and excessive use of water at once – This helps prevent overloading the system.

3. Watch What You Flush

Flushing inappropriate items can clog your septic system and lead to expensive repairs. Only flush:

• Human waste
• Septic-safe toilet paper

Avoid flushing:

• Wipes (even if labeled flushable)
• Feminine hygiene products
• Paper towels and tissues
• Cooking grease and fats
• Medications and harsh chemicals

These materials can cause blockages, kill beneficial bacteria, and lead to system failure.

4. Use Septic-Safe Products

Harsh chemicals can disrupt the balance of bacteria in your septic tank, making it less effective at breaking down waste. Opt for:

• Biodegradable, septic-safe household cleaners
• Natural alternatives like vinegar and baking soda for cleaning
• Non-toxic soaps and detergents

Avoid:

• Bleach and ammonia-based cleaners
• Antibacterial soaps, which can kill essential bacteria
• Drain cleaners, as they can damage pipes and disrupt the system

5. Maintain Your Drain Field

The drain field plays a crucial role in filtering wastewater before it reenters the environment. To keep it in good condition:

• Keep heavy objects off – Avoid parking cars, building structures, or placing heavy equipment on the drain field.
• Prevent tree root intrusion – Plant trees and shrubs far from the drain field to prevent roots from damaging pipes.
• Redirect rainwater – Ensure that gutters and landscaping direct excess water away from the drain field to prevent oversaturation.
• Avoid compacting the soil – Compacted soil can reduce the drain field’s ability to absorb water.

6. Avoid Using Additives

Many commercial septic additives claim to improve system function, but they can sometimes do more harm than good. Your tank already contains natural bacteria that break down waste effectively. Additives can:

• Disrupt the bacterial balance in your tank
• Cause solids to flow into the drain field, leading to blockages
• Waste money without providing real benefits

Stick to natural maintenance methods and regular pumping to keep your system healthy.

7. Address Issues Immediately

Ignoring early warning signs of septic system failure can result in major, costly repairs. Be on the lookout for:

• Slow drains – If sinks, tubs, or toilets drain slowly, your tank may be full or clogged.
• Gurgling sounds – Bubbling or gurgling noises in your plumbing could indicate an issue.
• Unpleasant odors – Foul smells inside or outside your home may signal a failing system.
• Standing water near the drain field – Puddles or soggy ground may mean your system is overwhelmed.
• Sewage backup – Wastewater backing up into your home is a severe issue that requires immediate professional attention.

If you notice any of these signs, contact a septic professional as soon as possible to avoid worsening the problem.

Conclusion

Proper septic tank maintenance is crucial to avoid system failures and expensive repairs. By following these best practices, you can ensure your system runs efficiently for years to come. Regular inspections, mindful water use, and proper waste disposal all contribute to a healthy and long-lasting septic system. Taking preventative measures now can save you time, money, and stress in the future.

FAQs

A constantly running toilet can be both frustrating and costly, as it wastes water and increases your utility bills. Understanding the causes behind this issue can help you identify and fix the problem efficiently. Below are some common reasons why your toilet may be running continuously and how to address them.

1. Faulty Flapper Valve

The flapper valve controls the release of water from the tank to the bowl. If it’s not sealing properly, water will continuously leak into the bowl, causing the toilet to run.

How to Fix:

• Check if the flapper is worn out or damaged.
• Replace it if necessary by purchasing a compatible flapper from a hardware store.
• Ensure the chain connecting the flapper to the flush handle is the correct length—not too tight or too loose.

2. Float Height Issues

The float in your toilet tank controls the water level. If it’s set too high, excess water flows into the overflow tube, causing the toilet to keep running.

How to Fix:

• Adjust the float height by turning the screw on the fill valve or bending the float arm slightly downward.
• Ensure the water level is about 1 inch below the overflow tube.

3. Leaky Fill Valve

The fill valve is responsible for refilling the tank after a flush. If it’s malfunctioning, water may continuously flow into the tank and out through the overflow tube.

How to Fix:

• Turn off the water supply to the toilet.
• Inspect the fill valve for wear or leaks.
• Replace the fill valve if necessary by following manufacturer instructions.

4. Damaged Overflow Tube

If the overflow tube is cracked or broken, water may continuously leak out, preventing the tank from filling properly.

How to Fix:

• Inspect the overflow tube for cracks or damage.
• If it’s damaged, replace it with a new one from a plumbing supply store.

5. Chain Problems

If the chain connecting the flush handle to the flapper is too short or tangled, it may prevent the flapper from sealing properly.

How to Fix:

• Adjust the chain length so there’s a slight slack when the flapper is closed.
• Ensure the chain isn’t caught under the flapper.

When to Call a Plumber

If you’ve tried these fixes and your toilet is still running, it may be time to call a professional. A plumber can identify deeper issues, such as problems with internal plumbing components or water pressure irregularities.

Conclusion

A running toilet can waste gallons of water per day, leading to higher bills and potential water damage. By identifying the root cause—whether it’s a faulty flapper, a misadjusted float, or a damaged fill valve—you can fix the issue quickly and prevent further waste. Regular maintenance and timely repairs will help keep your toilet functioning efficiently.

FAQs

DIY projects can be rewarding and cost-effective, but when it comes to plumbing, attempting repairs without professional expertise can lead to serious consequences. While fixing a minor leak or unclogging a drain might seem simple, more complex plumbing issues require specialized knowledge and tools. Here are some of the potential risks associated with DIY plumbing repairs.

1. Increased Damage and Costly Repairs

Plumbing systems are intricate, and an incorrect repair can worsen the issue. A small mistake can lead to leaks, burst pipes, or water damage, resulting in costly repairs that exceed the original problem’s cost. Additionally, temporary fixes may fail over time, leading to more extensive damage.

2. Water Damage and Mold Growth

Improperly fixed leaks can lead to water seeping into walls, floors, and ceilings. This creates the perfect environment for mold and mildew to grow, leading to health hazards and expensive remediation efforts.

Professional plumbers are trained to follow local building codes. DIY plumbing repairs might not comply with these regulations, potentially leading to fines or complications when selling your home. In some cases, insurance claims may be denied if unlicensed work is performed. Some jurisdictions require permits for plumbing work, and failure to obtain them can lead to legal consequences.

5. Lack of Proper Tools and Expertise

Plumbers have specialized tools to diagnose and fix problems efficiently. Without the right equipment, DIY repairs can be ineffective, temporary, or even worsen the situation. Professional-grade tools, such as pipe cutters, augers, and leak detection devices, are often not available to homeowners, making it difficult to achieve lasting solutions.

6. Voiding Warranties

Many plumbing fixtures and appliances come with warranties that require professional installation and repairs. Attempting to fix an issue yourself can void these warranties, leaving you responsible for all future repairs and replacements. This can be particularly costly for major appliances like water heaters, dishwashers, and filtration systems.

7. Environmental Impact

Incorrect plumbing repairs can result in wasted water, leading to higher utility bills and unnecessary strain on the environment. A small, unnoticed leak can waste thousands of gallons of water over time. Additionally, improper disposal of plumbing materials, such as old pipes and chemicals, can contribute to environmental pollution.

When to Call a Professional

If you experience any of the following issues, it’s best to call a licensed plumber:

• Persistent or major leaks
• Low water pressure
• Sewer line backups
• Issues with your water heater
• Burst pipes or major water damage
• Gas line repairs or installations
