Abstract
A bath waste and overflow drain system of the present disclosure may comprise both drain and overflow assemblies. The drain assembly generally includes a drain elbow, drain gasket, drain spud, drain trim, and drain stopper. The drain trim may possess weep channels that urge stagnated water from a periphery of the drain spud and into the drain. The overflow assembly generally includes an overflow elbow, overflow gasket, retaining nut, and overflow faceplate. The overflow faceplate may have bayonet channels that engage with a protrusion of the overflow elbow so as to accommodate variances in tub design when effecting an installation. The system according to an embodiment may also comprise test plugs of the overflow and drain varieties which are, together, operable to permit pressure-related tests of the system prior to completing an installation. The overflow and drain test plugs are simple to manipulate and install/remove with quick-engaging, complementary locking features.
