Our expert plumbers perform thorough backflow testing to identify any potential risks or issues in your plumbing system.

Backflow Prevention Device Installation

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 Backflow Testing and Certification

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 Device Repairs and Maintenance

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-Connection Control Surveys

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.

Emergency Backflow Prevention Services

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.

Backflow Device Upgrades and Replacements

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.

Ryen and Jordan did an exceptional job addressing a kitchen sink that wouldn't drain. They were professional, hunted the problem until it was resolved, and then made a quick fix to help prevent the issue from reoccurring. Moreover, they quoted me for a proper longterm fix and weren't aggressive or pushy. They blew my expectations out of the water and I wouldn't hesitate with using them again in the future. I hope that their great work and friendly disposition doesn't go unnoticed by any higher-ups!

I can't say enough good things about Matt and Elia from John the Plumber! Not only are they excellent problem solvers who really know their stuff, but they're also genuinely great people. They arrived right on time, were incredibly efficient, and were super friendly and professional throughout the entire experience. It's refreshing to deal with people who not only take pride in their work but also make the whole experience pleasant and stress-free. They went above and beyond, and their positive attitudes and dedication really stood out. I highly recommend Matt and Elia to anyone looking for reliable, knowledgeable, and genuinely caring plumbers. John the Plumber is lucky to have these two on their team! Thanks again, guys, for the outstanding service!

Had Tomas and his team come in to install a new sump pump pit system with backup. They did a fantastic job. They kept the worksite meticulously clean and kept me informed of all the steps as they happened. They accommodated a couple changes very easily and now I have peace of mind in case there is another flooding event. Would work with them again in a heartbeat
