Watco’s Innovator Shower Drain is a receptor-type drain for pre-formed shower bases. It features the Innovator orange test membrane, testable to 22 P.S.I., which eliminates the need for test balls, caps or plugs. It includes a heavy-duty, snap-on grid strainer that is 20% thicker than competitive grids. The grid is available in four finishes. Plumbers appreciate the E-Z grip installation tabs on the top piece and the squared-off ribs on the bottom receptor to aid tightening and installation. It includes a green, polycarbonate cover to protect the grid finish and prevent debris from entering the drain during construction.
