Why Install a Backwater Valve?

A backwater valve automatically closes when sewage begins flowing toward your property. This helps prevent contaminated water from entering your basement through floor drains, toilets and other plumbing fixtures.

​

• Previous basement or sewer backups

• Gurgling drains or toilets

• Sewage odours

• Water rising through basement drains

• A property located in a flood-prone area

• No existing sewer-backup protection

Frequently Asked Questions

​

Does a backwater valve prevent every type of flooding?

No. It protects against sewer backups but does not prevent flooding caused by groundwater, foundation leaks or failed sump pumps.

​

Can I use my plumbing while the valve is closed?

No. Avoid using toilets, sinks, dishwashers and washing machines while the valve is closed because wastewater cannot leave the property.

​

Does everyone qualify for the Toronto subsidy?

No. The property and installation must meet the City’s requirements. The City makes the final eligibility and approval decision.
