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.

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).

FAQ About Commercial Plumbing in Toronto & GTA
-
What does a commercial plumber do?
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?
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?
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?
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?

-
How often should commercial plumbing systems be inspected?
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?
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?
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?
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.
-
