What a backwater valve does
A backwater valve sits on your main sewer line. Wastewater flows out normally. When the sewer backs up toward your house, a flap closes so sewage can’t come up through your floor drain.
Backwater valves were not required in Edmonton homes built before 1989. If your home is older, it may not have one.
EPCOR’s subsidy, step by step
EPCOR’s Backwater Valve Subsidy pays up to $800 toward an interior or exterior backwater valve. It targets Edmonton homes built before 1989, homes that have had sanitary sewer backup, and homes in areas with previous neighbourhood flooding. The rules:
- The home must be separately serviced (single-family or duplex), must not already have a backwater valve, and must not have received the subsidy before.
- A professional plumber installs it.
- Use an eligible model: Adapt-a-Valve, Branch Line, Fullport, Retrofit or Top Check Fullport.
- Pass the City of Edmonton inspection and keep the green sticker with the permit number.
- Apply to EPCOR with the sticker, the paid invoice and the application form.
EPCOR’s pre-approval inspection is suspended until further notice. Subsidies depend on funding, first come, first served, with no guarantee. Full walk-through: Edmonton backwater valve subsidy, step by step.
Sherwood Park: Strathcona County rebate
Strathcona County rebates up to 50% of backwater valve supply and installation, to a maximum of $1,200, for single-family homes or separately serviced side-by-side duplexes built before 1989 and served by the County’s sewer system. Permits come first, then installation and the plumbing inspection, then the rebate application with your receipt and permit copy.
Insurance
Many insurers now require a backwater valve for sewer backup coverage. Ask your broker whether installing one changes your coverage.
What we do
We check your eligibility with you, install an eligible model, book the City inspection, and give you a paid invoice that shows the valve model for your application. If your sewer line is due for lining or replacement, we can install the valve during the same job.
