Backflow Prevention

Backflow prevention is not the most glamorous plumbing topic, but it is one of the most important. When water flows backward through your plumbing — due to a pressure drop, a water main break, or heavy demand on the municipal system — contaminated water can get pulled into your clean water supply. That means chemicals from irrigation systems, bacteria from cross-connections, or worse, sewage in your drinking water.

Ontario building codes and municipal bylaws require backflow prevention devices on many types of properties. If you have an irrigation system, a boiler, a commercial kitchen, or any connection to a non-potable water source, you likely need one. And once it is installed, most municipalities require it to be tested every year by a certified professional.

Relica Comforts handles the full scope — installation, repair, annual testing, and certification. We are familiar with the requirements across GTA municipalities and can tell you exactly what your property needs to stay compliant. We also install mainline backwater valves that prevent sewer backup into your basement, which is a separate but equally important form of backflow protection.
