2. Before construction, check whether the original pipeline is unblocked, then carry out construction, and then check whether the pipeline is unblocked after construction.
Hidden water supply pipes should be inspected for water supply, and newly installed water supply pipes must be pressurized according to relevant regulations without leakage. Only after passing the inspection can we enter the next working procedure.
3. Before construction, the drainage pipeline shall be temporarily sealed to prevent sundries from entering the pipeline.
4. When installing the water supply pipe with a pipe diameter of less than 25mm, pipe clamps should be installed at the corner, water meter, faucet or angle valve and at the pipe terminal 100mm, and the pipe clamps should be installed firmly.
Pipes are connected with threads, and exposed threads are required at the joints. After installation, it should be fixed with pipe clamp in time, and there should be no looseness between pipeline and pipe fittings or valves.
5, the installation position of various valves should comply with the design requirements, easy to use and maintain.
6. All joints, valves and pipelines should be tight, without leakage, and the pipeline slope meets the requirements.
7, all kinds of pipelines shall not change the original nature of the pipeline.
8. Pipes should be installed with special tools. When assembling, the standard reamer must be used to slot the nozzle on the aluminum-plastic pipe to prevent damage to the double-layer retainer inside the copper joint, and leakage is not allowed.
9. The joints between pipes and valves should be tight, and the pipes should be connected with threads, and the joints should have exposed threads. After installation, they should be fixed with pipe clamps in time without leakage.
10. Valves and faucets are installed correctly, used flexibly and conveniently, the water outlet is unblocked, and the water meter is running normally.
Under the premise of satisfying the use, valves, water meters, etc. Can be in a relatively hidden position, but also can be properly decorated.
