A backwater valve is a one-way door on your sewer line. When the municipal sewer surcharges in a storm, it closes and keeps sewage out of your basement. We handle the permit, the installation and the inspection.
A backwater valve is installed on the main sanitary drain in the basement floor. Under normal conditions wastewater flows out freely; when the municipal sewer backs up during heavy rain, the valve flap closes and stops sewage from entering the home. Hayes Plumbing installs backwater valves across Durham Region, handles the plumbing permit and municipal inspection, and can supply the invoice and inspection record that the Region of Durham's basement flooding loan program asks for.

Common questions about backwater valve installation in Oshawa and Durham Region.
Look for a round access lid in the basement floor near the floor drain or where the sewer line leaves the house. If you are unsure, a camera inspection confirms it.
Not easily. In Durham Region the installation needs a plumbing permit and an inspection, and it involves cutting into the main sewer line, so we recommend a licensed plumber. The Region's basement flooding loan program also requires a licensed plumber. Done wrong, it can cause leaks, blockages and code violations that affect insurance.
A quality valve lasts 15 to 25 years with maintenance. The rubber flap may need replacement every 5 to 10 years, and an annual inspection catches wear early.
It protects against sewer backup specifically. Groundwater through foundation cracks or a failed sump pump needs a sump pump and grading solutions, which we can combine with the valve.
Yes. Sewer backflow valve is another name for a backwater valve: a valve on the main sewer line that closes when sewage flows back from the municipal sewer, so it cannot come up through your basement drains. It is different from a backflow preventer, which protects the drinking water supply and is covered by our commercial backflow testing service.
