At the overflow outlet at the end of the bathtub, until the project is completed, it is because these components will often be damaged at the end of the construction plan. In addition, the fittings used at the outlet must be inspected for leaks before the inspection procedure is completed. The test involves flowing water through the discharge outlet until it reaches a height above the bathtub, and the tester then decides if any fitting leaks have occurred. Therefore, at the beginning of the test operation, a plug was placed in the bottom drain of the bathtub, and a sealing plate was placed at the end of the bathtub above the overflow outlet. . A central opening. At the plate, there are small screw holes, where the piping fixtures. In some screw orifices are located directly at the orifice, which is covered by the test procedure, which usually involves entering into the pipe in the wall to seal. Furthermore, existing secret systems must be removed. For decoration, the two screws are used in the condition of the plate orifice. Two of the existing overflow plates are in which there are two or four two orifices in the middle adjacent to the central opening are used to attach the plate. There is an accessory to keep the item in the condition so that the middle of the access opening is located. Applicable when completed in this condition. Regardless of how a bladder is filled through the large central opening, and the tube is sealed when the bladder is inflated. The sheet is typically held by two screws when the decorative sheet is installed. The screw openings are either provided with four 200404974 openings. Some efforts have been implemented to seal the bath ’s red vapor vent through a diaphragm and then cut the diaphragm when testing is complete (see US Patent: 5,890,241 #b). However, systems for including a diaphragm sometimes involve screws and guards' and are not always convenient to be installed and removed after testing. [Content] ^ Therefore, one of the main objects of the present invention is to provide a Bathtub overflow = port seal, which is very easy to sorrow for testing purposes' and is easily made to be operable for overflow use when testing is complete.
