Our back flow preventer valve can be solvent-welded for a watertight connection. The installation is simple and efficient.
The backwater valve is made of sturdy PVC for high impact strength and resistance to heat and corrosion.
Designed for connecting 4-inch PVC drains in the drainage system, this valve prevents the backflow of water in the pipeline due to pressure reduction or other potential causes.
The backflow valve within the DWV system is designed to connect PVC sewers and drains, making it a good choice for sewage disposal in homes and specific industries. It serves to block sewer backflow.
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.
