Sewage can back up into the basement if the City's sanitary sewer pipe is full due to large amounts water.

Solution: Flood proofing devices.

Homes prone to flooding may benefit from plumbing improvements. These include.

  • Backwater valve (BWV)
    • A sewer BWV is designed to protect your home in the event that the sewer system wants to come back into your home. A BWV is a on-way valve that acts as a defense against flooding, provided that the BWV is maintained.
    • A BWV is comprised of a flap with small floats to rise which would then raise the flap blocking the sewage from continuing through the pipe.
    • It is recommended you clean your BWV once a year.
    • Please visit the Backwater Valve Protocol Website for installation of a Backwater valve.
