The crane was damaged when the construction plan was about to end. In addition, the pipe fittings used for the water outlet must be inspected before the inspection process is completed. The test involves flowing water through the drain, the outlet 'until it reaches a height above the bathtub, and the tester then decides if any plumbing leaks occur. So 'At the beginning of the test operation, a plug system was placed in the beta drain of the bath rainbow' and a sealing plate was placed at the end of the bathtub above the overflow outlet . The existing overflow plate has a central opening σ therein. There are two or four small screw holes in the plate adjacent to the central opening, two of which are used to hold the plate to the piping fixture. In some cases, an accessory is present so that the screw aperture is seated directly at the towelwell of the access aperture. In this state of the towel, the hole U was made available for use in the test program at 7G per day. In any case, the test procedure usually involves filling a pouch into a tube in the wall via a large central opening and the I-piece is sealed when the pouch is inflated. Furthermore, existing sealing panels must generally be removed when decorative panels are installed. The decorative plate is typically held by two screws, which use the plate's screw opening or an opening outside the two 1224659 in the case where four holes are provided.
