A small device, a lot of peace of mind
A check valve prevents wastewater from coming back into your pipes in the event of an overload in the municipal network. In other words: he keeps what should come out... outside.
This simple mechanism can save you from costly damage, mold, and endless insurance. At Plomberial, we don't just install it — we choose the right model, for the right place, with a professional and durable installation.
Is a check valve mandatory?
In several municipalities in Quebec, the installation of a check valve is required on any new construction or major renovation. If you have any doubts, we can come and see and advise you, without obligation.
Our team quickly checks if your home has one (and if it still works), then offers you a clear and adapted solution. It doesn't get any more complicated than that.

Testimonies
“After several sewer backups, I had enough! They put a check valve on me and since then, even with the heavy rains, no problem. Peace at last!”

“No problems since installation!”
“Installation in accordance with all documents.”
A check valve is a plumbing device that allows water to flow in only one direction, preventing backflow. It protects your drinking water against contamination and prevents sewer returns during heavy rains or municipal backups.
The installation of a check valve is not mandatory everywhere, but highly recommended and required by several Quebec municipalities in areas at risk of flooding. Check with your city, as some even offer grants to encourage this preventative installation.
The cost varies according to the type of valve, the accessibility of the pipes and the complexity of the work. The investment pays for itself quickly by avoiding the costly damage caused by sewer backups. Request a detailed quote for your specific situation.
Slow flows, unusual pipe noises, sewer odors, stagnant water near the floor drain, or minor backflows indicate a faulty valve. Regular maintenance and annual inspection extend its lifespan.
A quality check valve lasts between 15 and 25 years with proper maintenance. An annual inspection is recommended to verify its proper functioning, clean up accumulated debris and lubricate moving components according to the manufacturer's recommendations.
