Backflow prevention is essential to protecting your property’s water supply from contamination caused by reverse water flow. At John The Plumber, we specialize in installing, maintaining, and repairing backflow prevention devices to ensure the safety of Ottawa’s water distribution system.
Ignoring backflow prevention measures can lead to serious health hazards, water contamination, and violations of local regulations. With our expertise, we’ll safeguard your water and ensure compliance with Ottawa’s strict water safety standards.
Proper installation is the cornerstone of an effective backflow prevention system. Our licensed plumbers will assess your property, determine the right type of backflow prevention device based on hazard levels, and install backflow devices in compliance with Ottawa’s regulations. Whether it’s a double-check valve assembly (DCVA) or a reduced pressure zone (RPZ) assembly, we’ll ensure your water supply is safeguarded.
Annual testing of backflow preventers is a critical part of maintaining compliance with Ottawa’s regulations and ensuring water safety. Our certified technicians conduct detailed backflow testing to verify your device’s functionality, detect any irregularities, and provide the required certifications.
Backflow devices must be in top working condition to provide maximum protection. Over time, wear and tear can compromise their performance. Our repair and maintenance services address issues like:
Faulty Valves • Pressure Problems • Leaks
Regular maintenance extends the lifespan of your device and ensures consistent water safety.
Cross-connections are potential points in your plumbing system where contamination could occur, posing risks to the drinking water distribution system. Our cross-connection surveys identify these risks and recommend solutions to prevent contamination. These inspections are critical for both residential and commercial properties.
A backflow emergency can compromise water safety and pose immediate risks to health and property. Our 24/7 emergency plumbing services ensure prompt resolution of issues like backflow device failures or sudden contamination threats.
If your current backflow device no longer meets safety standards or is beyond repair, our technicians can replace it with a modern, code-compliant solution such as a reduced pressure principle assembly. Upgrading your system ensures reliable performance and continued compliance with local by-laws.
If you’ve received a letter from the City of Ottawa about backflow testing, device installations, or site surveys, don’t worry. John The Plumber is here to help. The City’s backflow prevention program is designed to protect Ottawa’s drinking water supply by identifying risks, ensuring protective devices are installed, and maintaining compliance with safety standards. Property owners must install backflow prevention devices as mandated by the Water Supply By-law, which includes determining the appropriate type of device based on the specific hazard level of each property.

I had a great experience with Owen. He was on time, got to work immediately, told me about my options after he finished his initial inspection and about the price. Owen was professional, knowledgeable and caring about doing his work. I recommend John The Plumber and I will use them for any future repairs or installation. Thank youPosted on Google![]()

I've used John The Plumber 4 times now. There is absolutely no reason to ever use any other company. Every technician they've sent is extremely courteous, professional and fast. Our last appointment was with Alex. We received an alert from the city that we had a leak. Alex detected a leak and ended up replacing our old toilet. The toilet replacement was done so fast that I couldn't believe it. This company obviously prides itself on great customer service and quality work. Alex is another fantastic representative of the company and did great work. Thanks!Posted on Google![]()

Terrific plumbers. Had Eric come in for an emergency leak and he prioritized ours given the urgency and showed up within 30 mins. Kept communication open and transparent throughout, helped me understand the issues clearly and made sure the repairs and installation to shower and faucet were adequate. They definitely tailor experiences to each clients’ needs which i really appreciate and Eric is a superb plumber to get for almost any issues. Highly recommend
