ABSTRACT:
An overflow system for a bathtub has an overflow port and has a drain pipe in connection with the overflow port. A flexible diaphragm is secured to and seals the port by a plate having a center opening. The diaphragm seals the overflow port when the system is being tested for leaks with pressurized fluid. Following the test, when the fluid is removed, the diaphragm is cut or slashed to open the overflow port to provide fluid flow. A cap covering the plate and the diaphragm is secured to the drain pipe and covers the plate and the diaphragm.
