DUAL UNION DRAIN VALVE WITH REVERSIBLE CHECK INSERTS
A dual union drain valve assembly has one or more reversible check valve inserts in the fitting(s) that are coupled to the drain valve body. The coupling of the fittings to the drain valve body is done using union couplings permitting the easy installation and/or reversal of the check valve insert(s). In addition, the union couplings permit removal of the dual union drain valve assembly from the surrounding plumbing system for service or replacement of the dual union drain valve assembly.
