3) Other sanitary wares should be installed stably after indoor decoration is basically completed.
Second, the operation process
1. process flow
Installation preparation → sanitary ware and fittings inspection → sanitary ware installation → sanitary ware fittings pre-installation → sanitary ware stable installation → sanitary ware and wall, ground gap treatment → sanitary ware appearance inspection → water testing.
2. Sanitary ware should be inspected and cleaned before stable installation. Accessories and sanitary ware should be matched. Some sanitary wares should be prefabricated before installation.
Third, the finished product protection
1. Sanitary ware shall be protected from collision during handling and installation. After the installation is stable, the drain of sanitary ware should be blocked with protective articles, and the chrome-plated part should be wrapped with paper to avoid blockage or damage.
2. When picking holes in glazed tiles and terrazzo walls, it is advisable to gently pick off the glazed surface with an electric drill or a small chisel. The prescription for connecting the bottom of the brick to the ash layer can be a little harder, but not too hard, so as not to connect the surface or shake it into an empty drum.

Fourth, the quality problems that should be paid attention to
1. The squatting pan is uneven and tilted left and right. Reason: When the installation is stable, the front and both sides of the pad brick are not firm, the coke residue is not checked after filling, and it is difficult to repair after plastering, which leads to the dislocation of the high water tank and the toilet.
2. The handles of the high and low water tanks are not flexible. Cause: When installing the internal fittings of high and low water tanks, the positions of the three main components in the water tanks are unreasonable.
