Conbraco Double Check Assemblies

Conbraco double check valve assemblies are an economical and in-line repairable alternative to bulky, high head loss backflow preventers.

Available in sizes 3/4 to 2 inches, Conbraco Double Check Valve Assemblies guard against back-pressure or back-siphonage caused by cross connections between potable water lines and substances that are objectionable but not hazardous.
