What should be paid attention to in the acceptance of water and electricity during decoration?

The quality acceptance of hydropower projects in residential decoration, also known as concealed projects, is very important. It is the internal quality of the whole house decoration, which is related to the safety and convenience of water and electricity use and the service life after occupancy, and must not be ignored.

In general, it is recommended that the owner invite a third-party professional to accompany the inspection to ensure the inspection quality. If the owner does not invite professionals to carry out the inspection, he can carry out the inspection according to the following requirements, and leave a written record for the record when necessary.

At present, the decoration company generally entrusts the supplier to install the water supply pipeline, and the supplier uses the instrument to carry out pressure leakage detection on site and issue a test certificate, which is kept by the decoration company and submitted to the owner together with other materials such as the actual trend diagram of the pipeline at the end of the decoration. The water supply pipes and valves shall be fixed with firm clamps.

Wires should be laid through PVC pipes, and the total cross-sectional area of wires should not be greater than 40% of PVC pipes (for example, the sixth branch pipe can only wear four wires of 2.5 square millimeters), and wires should not be laid through the same pipe as telephone lines, cable TV lines and network lines. The thickness of PVC pipe wall is above 1.2 mm, so it should feel neither soft nor broken when held by hand. Wire tubes, hot water pipes and gas pipes should be kept at a certain distance and should not be close to each other.

Wires should go through the wall, not under the floor, under the floor tiles or at high altitude. Switch position from the ground 130 cm, socket position from the ground about 20 cm.

The wires on the ceiling should not be placed on the keel, and junction boxes, lamps and ceiling fans should not be fixed on the keel. The keel should be treated with fire prevention, and the size of the keel should meet the bearing requirements of the ceiling.

The decoration company should give the actual trend diagram of electric wires and water pipes to the owner for preservation. At present, a considerable number of decoration companies have not provided customers with the actual route map of pipelines, which has brought great inconvenience to the owners for future maintenance.

Wood joists should be dry, and the ground and wood joists should also be treated with moisture, but asphalt should not be used to prevent moisture. After leveling, wooden joists shall not be fixed with wedge plugs. Wooden joists should be fixed with hammer-type special expansion nails, or with one nail and one screw, and not only with one nail and one screw. The floor is noisy, and the irregular laying of wooden joists accounts for a considerable proportion.

After all projects are accepted, the owner can sign the acceptance sheet for confirmation. Remember to keep a copy, and if there is a dispute in the future, you can also have a voucher.

After reading the above precautions for hydropower acceptance, you must have known how to accept the concealed hydropower project. Water and electricity decoration needs to accompany the house for life, so people must pay attention to it. In addition, professionals must be invited to decorate this project to reduce unnecessary troubles in the future.
