A backwater valve shuts off excess waste water from coming up from a sewer system and entering your home through your floor drains, toilets and sinks. As water passes through the device, the valve closes to prevent backflow, thus preventing flooding.

Although a backwater valve does not provide 100% guarantee, it can get the job done when installed properly by a professional. Call Potz Plumbing Ltd for a new installation or maintenance of a previous backwater valve install.

Backwater valves should be maintained once every 2-3 months to ensure the valve is in proper working condition.
