What Is a Backwater Valve and Why Is It Important
A backwater valve is a plumbing device that prevents sewage from flowing back into your home during heavy rain or city sewer overloads. It’s one of the most effective ways to protect your basement from contamination, flooding, and expensive repairs.
What Is Backflow
Backflow occurs when wastewater reverses direction in your pipes — usually due to sewer overload or stormwater infiltration. This can cause contaminated water to enter your home, damaging floors, walls, and foundations.
What Is a Backwater Valve
The valve is installed in the main sewer line of your home. When the system detects backflow pressure, it automatically closes, blocking sewage from entering your home. Once the pressure normalizes, it opens again to restore normal drainage.

Reviews about us
Quick, professional and at very reasonable cost. No hidden costs. The installation was complicated as the municipal sewage backed up when the pipe was cut, but the team did not complain despite working in harsh conditions.

Leaquida Waterproofing was prompt, courteous and thorough. We would recommend to anyone. We had a backwater valve installed. I called Sunday, got a quote Monday, has the work done the following Monday (including issuing of building permit).
