The backwater valve is made of sturdy PVC for high impact strength and resistance to heat and corrosion.
Intended for use with 4-inch PVC drains, this valve is made to stop water from flowing back in the pipeline when pressure drops or other issues occur.
Thickened rubber rings embedded in the water stop baffle guarantee a watertight seal, and the access cover is also sealed with EPDM rubber to prevent water leakage.
Our back flow preventer valve can be solvent-welded for a watertight connection. The installation is simple and efficient.
The backflow valve, as part of the DWV system, is suitable for connecting PVC sewers and drains. Ideal for sewage disposal in household and certain industries, it prevents sewer backflow.
