• Designed to provide quiet operation in sump pump or sewage ejector pump systems Spring controlled rate of closing prevents slamming and eliminates noise True union sockets for easy servicing and direct socket connection for installation in confined space

Spears® quiet check valve has been designed to provide quiet operation in sump pump or sewage ejector pump systems typically found in home basements. The backflow of the water column in the discharge pipe can slam conventional check valves closed, producing a disturbing thump when the pump shuts off. The quiet check valve uses a spring controlled rate of closing to prevent slamming and eliminates the noise. Each Spears® quiet check valve contains both regular socket eNDS® for direct solvent cement connection of the valve and true union style end connectors for easy valve removal or replacement.
