1-1/2" DWV PVC Backwater Swing Check Valve
The 1-1/2" Backwater Valve is a crucial device for protecting basements and other low-level areas from the backflow of sanitary sewer, storm sewer, or septic systems. This simple yet effective device operates by allowing wastewater to exit normally through a lightweight flapper during standard operation. However, during a backflow event, the flapper automatically seals closed, effectively stopping the flow from reaching interior drains and preventing it from entering the living space.
This valve is specifically a 1-1/2 inch DWV (Drain, Waste, Vent) PVC backwater valve with hub connections, designed as a plastic socket-connect swing check valve. It is recommended for installation on all branch lines serving low-level appliances, keeping the main line open for discharge and venting. Any drain openings situated behind this backwater valve will be protected from backflows. The P-WAT-3250 can also be installed on the main line before it enters a building for comprehensive protection. Within Tommy Car Wash Systems, this valve serves as a direct replacement part for the Tommy Flat Mat Washer (60003).
