The Watco 901-FA-PVC-CP Innovator 901 Series foot actuated bath waste half kit is designed for bathtubs, providing drainage and a sealing mechanism. This half kit includes the overflow and drain elbows, overflow plate assembly, test plug, membrane, stopper, and drain, typically requiring the main tee and some connecting PVC piping to be supplied separately. The assembly features 1.5-inch Schedule 40 PVC for the pipe components, with visible trim finished in polished chrome. It is engineered to fit most bathtubs up to 16 inches deep. Key features include a screwless overflow plate for a clean appearance and a built-in test membrane and drain test plug, allowing for pressure testing up to 22 psi (equivalent to five floors) before final installation. The overflow elbow is self-centering and self-aligning to prevent leaks. The strainer body and drain elbow utilize 1-1/2 inch - 11-1/2 NPSM coarse threads with a 1.865-inch major diameter. This assembly complies with ASME A112.18.2-2015 and CSA B125.2-2015 standards.
