Backwater Valve Subsidy Program
The City of Richmond Hill pays toward a backwater valve for existing single-family, duplex and triplex homes. Funding is limited and first come, first served.
| Work | Amount |
|---|---|
| Backwater valve, licensed plumber or drain contractor | up to $1,500 |
Get a City building permit first, and don't cover the valve until the plumbing inspector approves it. Downspouts must be disconnected. Apply within six months of finishing, with a paid-in-full itemized invoice. Program rules change; confirm with the official program before you book the work.
Bylaws & permits in Richmond Hill
- Backwater valves need a City of Richmond Hill building permit and a plumbing inspection before the work is closed up.
- Older homes with storm weeping tile tied into the sewer must redirect it to a sump pump that discharges outside to qualify for the subsidy.
- The subsidy is paid once per property, and do-it-yourself labour isn't covered.
