    Plumbing Solutions for Commercial Properties in Toronto & GTA

    Reliable plumbing is essential for keeping commercial properties operating safely and efficiently. Whether it's an office building, restaurant, retail store, warehouse, or industrial facility, plumbing failures can disrupt business operations, damage property, and lead to costly downtime. Commercial systems are larger, more complex, and subject to stricter regulations, making professional service a critical investment rather than an occasional repair.

    POM Plumbing provides commercial plumbing services Toronto businesses rely on for everything from system installations and upgrades to inspections, maintenance, and commercial plumbing repair. Our experienced team works with water supply, drainage, and sewer systems in commercial properties of all sizes, delivering practical solutions tailored to each facility's operational needs.

    Using advanced diagnostic equipment and proven repair methods, we identify the root cause of plumbing issues and recommend long-term solutions instead of temporary fixes. Every project is completed in accordance with Ontario Building Code requirements and industry best practices, helping property owners and facility managers maintain reliable plumbing infrastructure while reducing the risk of unexpected failures.

    Why Commercial Plumbing Requires Specialized Expertise?

    Commercial plumbing systems are designed to support higher water demand, larger pipe networks, and more complex infrastructure than residential properties. From office buildings and restaurants to warehouses and industrial facilities, these systems must operate reliably while meeting Ontario Building Code and safety requirements.

    Unlike residential plumbing, commercial plumbing Toronto projects often involve multi-storey drainage systems, commercial water heaters, backflow prevention devices, and specialized equipment. Accurate diagnostics and expert workmanship are essential to minimize downtime, prevent recurring issues, and keep your business running efficiently.

    Commercial vs Residential Plumbing: Key Differences

    Factor Residential Plumbing Commercial Plumbing
    Daily load One household Dozens to hundreds of employees, tenants and visitors
    System layout Short pipe runs, one or two storeys Larger pipes, multi-storey drain stacks and water risers
    Hot water Single tank or tankless heater Commercial water heaters and building-wide distribution
    Compliance Permit when required Ontario Building Code, annual backflow testing, grease interceptors for food service
    Cost of downtime Inconvenience Closed washrooms, halted kitchens, lost revenue and tenant complaints
    Scheduling Any convenient time Work planned around business hours to keep operations running

    Our Commercial Plumbing Services in Toronto, Ontario

    POM Plumbing delivers commercial plumbing service Toronto businesses can depend on for installations, repairs, system upgrades, and ongoing maintenance. We work with office buildings, restaurants, warehouses, retail centres, healthcare facilities, and industrial properties, providing solutions tailored to the unique demands of commercial plumbing systems.

    Commercial Drain Cleaning

    Our commercial drain cleaning service is designed to keep high-use drainage systems operating efficiently. We remove grease, sludge, debris, and stubborn blockages using professional equipment, including hydro jetting. The service also includes cleaning of main drain lines and vertical stacks to help maintain reliable drainage throughout your facility.

    Sewer Line Services

    We provide complete sewer line services, including CCTV inspections, drain cleaning, repairs, and full sewer line replacement. Our technicians accurately identify the source of the issue and restore proper system performance while minimizing disruption to your business operations. Every sewer project starts with a drain camera inspection to locate cracks, root intrusion and blockages before any digging begins.

    Pipe Repair & Replacement

    Our team repairs and replaces commercial water supply, drainage, and sewer piping for existing buildings, renovations, and system upgrades. Services include replacing aging risers, main water lines, and damaged pipe sections using durable materials and installation methods that comply with current Ontario Building Code requirements. We also replace outdated and failure-prone materials, including Kitec pipe replacement and lead pipe replacement for older commercial buildings

    Plumbing Installation & System Upgrades

    From new commercial construction to renovation projects, we design and install complete plumbing systems tailored to your facility's requirements. We also modernize outdated plumbing infrastructure, upgrade existing systems, and retrofit components to improve efficiency, reliability, and compliance with current Ontario Building Code standards.

    Backflow Prevention & Testing

    Our certified technicians install, inspect, test, repair, and maintain backflow prevention devices to protect potable water supplies from contamination. We also perform required testing to help commercial properties remain compliant with municipal safety regulations.

    Grease Management & Kitchen Stack Cleaning

    Restaurants, food courts and institutional kitchens send large volumes of fats, oils and grease into their drains every day. We clear grease-choked lines with hydro jetting and provide kitchen stack cleaning for multi-storey buildings, so shared drain stacks keep flowing and tenants avoid backups.

    Water Heating & Riser Replacement

    Aging domestic water risers cause low pressure, rusty water and leaks on several floors at once. We plan and complete riser replacement and upgrade domestic hot and cold water distribution for commercial and multi-residential buildings, phasing the work to keep water service running for occupants.

    Preventative Plumbing Maintenance

    Scheduled maintenance costs less than an emergency call during business hours. We inspect water supply and drainage systems, flush drain lines, test backflow devices and report on the condition of your plumbing, so you can budget repairs before they turn into shutdowns.

    Emergency Commercial Plumbing

    Our commercial plumbing services Toronto include 24/7 emergency response for burst pipes, major leaks, sewer backups, water heater failures, and other urgent plumbing issues. When immediate repairs aren't possible, we stabilize the system to minimize damage before completing a permanent repair, helping businesses return to normal operations as quickly as possible.

    Every service we provide is designed to keep your commercial plumbing system operating safely, efficiently, and in compliance with current standards. Whether you need a planned system upgrade, ongoing maintenance, or emergency repairs, POM Plumbing delivers reliable solutions for commercial properties across Toronto and the GTA. To discuss your project or request a service, call us today at (905) 625-8777.

    If water has already reached floors or equipment, our team can also help with flood restoration after the leak is stopped.

    Commercial Plumbing Compliance in Toronto

    Commercial properties in Toronto answer to provincial codes and city by-laws that do not apply to most homes. Our team keeps these rules in mind on every job, so your plumbing passes inspections and your business avoids fines.

    Ontario Building Code

    All plumbing work must meet the Ontario Building Code. The (2024 edition of the Building Code) came into effect on January 1, 2025, and applies to new installations, renovations and system upgrades.

    Licensed Plumbers Only

    Plumbing is a compulsory trade in Ontario. Only people who hold a Certificate of Qualification, a Provisional Certificate or a Registered Training Agreement — and appear on the (Skilled Trades Ontario Public Register) — can legally do plumbing work.

    Backflow Prevention Testing

    Under Toronto's Water Supply By-law, industrial, commercial, institutional and Part 3 residential properties must have a backflow prevention device. Each device must be tested when installed, within 72 hours after it is cleaned, repaired or replaced, and (at least once a year).

    Grease Interceptors for Food Service Businesses

    Toronto's Sewers By-law requires food service establishments to install and maintain a grease interceptor on any pipe that connects to the sanitary sewer. Hydro-mechanical interceptors must be serviced every four weeks or before grease and solids reach 25% of the liquid volume, and records must be kept for at least seven years. Violations can lead to (fines of up to $100,000).

    Common Plumbing Issues in Commercial Buildings

    Commercial plumbing systems operate under constant demand, making regular wear and unexpected failures inevitable. Identifying issues early helps minimize downtime, reduce repair costs, and extend the lifespan of your plumbing infrastructure. When problems arise, timely commercial plumbing repair can help prevent minor issues from developing into major disruptions.

    Some of the most common plumbing issues in commercial properties include:

    Problem Warning Signs Risk for Your Business How We Fix It
    Blocked drains and sewer lines Slow drains, gurgling, odours Closed washrooms or kitchen, sewage backup Commercial drain cleaning and hydro jetting
    Leaking or damaged pipes Stains, damp walls, rising water bills Water damage to stock and finishes Leak location, pipe repair and repiping
    Water heater problems Lukewarm water, rusty water, leaks at the tank Tenant and guest complaints, health-code issues Repair, replacement or riser upgrade
    Backflow device failures Failed annual test, leaking relief valve By-law non-compliance, contaminated supply Backflow prevention device repair and re-testing
    Worn drain stacks Repeated backups on lower floors Damage in several units at once Stack cleaning, power flushing and repair
    Sewer backups and flooding Water at floor drains after heavy rain Flooded basement, equipment and records Backwater valve installation and 24/7 emergency response

    Addressing these issues promptly helps protect your property, maintain business continuity, and avoid more extensive repairs in the future.

    Preventative Maintenance Schedule for Commercial Plumbing

    Most costly failures in commercial buildings start as small problems that a routine check would catch. Use the schedule below as a starting point — we adjust it to your building’s age, size and usage after the first inspection.

    Task How Often Why It Matters
    Backflow prevention device test At least once a year (City of Toronto requirement) Protects the drinking water supply and keeps you compliant
    Hydro-mechanical grease interceptor service Every four weeks, or before grease and solids reach 25% (City of Toronto requirement) Prevents grease blockages and by-law fines
    Full plumbing system inspection Annually for most businesses; more often for restaurants, healthcare and high-traffic buildings Finds leaks, corrosion and wear before they cause shutdowns
    Drain camera inspection When backups repeat or before renovations Shows the real condition of drain and sewer lines
    Kitchen stack and drain line flushing Based on inspection results and kitchen volume Keeps shared stacks clear in multi-storey buildings
    Catch basin cleaning Based on inspection results Prevents parking-lot flooding and odours

    How Much Does Commercial Plumbing Cost in Toronto?

    There is no flat price for commercial plumbing — the cost depends on your building and the work involved. After an on-site assessment we give you a written estimate with no hidden costs, so you can approve the scope before we start.

    The main factors that affect the price:

    • Type and size of the property (restaurant, office, warehouse, healthcare or multi-storey building)
    • Access to pipes and equipment — open ceilings versus finished walls, floors or underground lines
    • Scope of work — a single repair, a system upgrade or a full replacement
    • Materials and specialized equipment, such as hydro jetting or camera inspection
    • Scheduled service versus an after-hours emergency call

    FAQ About Commercial Plumbing in Toronto & GTA

    • What does a commercial plumber do?

      icon

      A commercial plumber installs, repairs and maintains plumbing in business, institutional and industrial buildings. That covers water supply lines and risers, drainage and sewer systems, commercial water heaters, backflow prevention devices and fixtures in washrooms and kitchens — all built for heavier daily use than a home system.

    • What should I look for when choosing commercial plumbing contractors in Toronto?

      icon

      When selecting commercial plumbing contractors in Toronto, look for a licensed and insured company with experience working on commercial properties similar to yours. It's also important to choose a contractor that follows Ontario Building Code requirements, offers transparent pricing, and can handle both planned projects and emergency repairs.

    • Do commercial plumbers in Ontario need a licence?

      icon

      Yes. Plumbing is a compulsory trade in Ontario, so anyone doing plumbing work must hold a Certificate of Qualification, a Provisional Certificate or a Registered Training Agreement and be listed on the Skilled Trades Ontario Public Register. You can check a plumber’s status on the register before hiring.

    • How much does commercial plumbing service cost in Toronto?

      icon

      The price depends on the type and size of your property, access to the pipes, the scope of work, the equipment needed and whether it is a scheduled or emergency call. We assess the system first and give you a written, itemized estimate with no hidden costs before any work begins.

    • Do you offer 24/7 emergency commercial plumbing in Toronto?

      icon

      Yes. We provide 24/7 emergency response for burst pipes, major leaks, sewer backups, water heater failures and other urgent problems across Toronto and the GTA. Call (905) 625-8777 and our team will help you contain the damage and restore service as quickly as possible.

    • How often should commercial plumbing systems be inspected?

      icon

      The ideal inspection schedule depends on the size, age, and type of your commercial property. Many businesses benefit from annual inspections, while restaurants, healthcare facilities, and high-traffic buildings may require more frequent maintenance to help identify issues before they lead to costly repairs. Some checks are set by law — for example, backflow prevention devices in Toronto must be tested at least once a year.

    • How often does a backflow preventer need to be tested in Toronto?

      icon

      Under the City of Toronto’s Water Supply By-law, a backflow prevention device must be tested when it is installed, within 72 hours after it is cleaned, repaired or replaced, and at least once a year. The test must be done by a certified Cross Connection Control Specialist, and the report is submitted to the City.

    • Do restaurants in Toronto need a grease interceptor?

      icon

      Yes. Toronto’s Sewers By-law requires food service establishments to install and maintain a grease interceptor on any pipe that connects to the sanitary sewer. Hydro-mechanical interceptors must be serviced every four weeks or before grease and solids reach 25% of their liquid volume, and fines can reach $100,000.

    • How do I know if I need commercial plumbing repair or a full system replacement?

      icon

      A professional inspection is the best way to determine the right solution. While many plumbing issues can be resolved through commercial plumbing repair, severely deteriorated piping, recurring leaks, or outdated plumbing infrastructure may require partial or complete system replacement for long-term reliability.

    • How can I request a quote for commercial plumbing services?

      icon

      Simply contact POM Plumbing by phone or through our online contact form. After discussing your project, our team can recommend the most suitable solution and provide a detailed estimate based on your property's specific requirements.
