Why bother
Basement flooding from sewer backup is costly. Backwater valves reduce that risk, and some municipalities have helped with the cost to protect both homes and the sewer system. Programs change, so always check current terms.
Doing it, in order
- Visit the Town of Newmarket website, or your own municipality's site, and search for flood protection subsidies.
- Read eligibility rules: home type, permit, inspection.
- Apply before work begins if pre-approval is required.
- Book a licensed plumber and get a permit.
- Keep invoices, photos and inspection results.
- Submit the claim within the deadline.
Some programs also help with downspout disconnection or sump pump installation.

Physically, the valve is a flap in a clear-top body cut into the main drain under the basement slab. The plumber breaks out concrete, cuts the cast iron or ABS, sets the body level, and pours back around an access box so the flap can be checked and rinsed each spring.
