Install a PVC 3" BACKWATER VALVE in a floor drain 🌧🏡
A backwater valve is a backflow prevention device used to prevent outbound water through a dwelling's drain pipes from re-entering "back flowing" into a home. The valve contains a flap that allows water to exit the home, but closes to prevent the back flow into the home.
