Check the brand of the water pipe to ensure consistency with the contract. Wipe the words on the water pipe vigorously with your hands. Fake goods can erase the font. If the materials are found to be inconsistent, the decoration company must replace the materials or make up for the price difference; Generally, we have drawings for decoration of water and electricity projects, so we must carefully compare the drawings to see if they are laid according to the lines on the drawings and if there have been any changes to the lines. Otherwise, encountering perforation problems in the later stage may damage wires or water pipes, which is not worth the loss. When inspecting the goods, we also need to bring the quotation together for comparison to see if the materials used for water and electricity testing and installation belong to the brand we purchased

Some decoration companies may replace one thing with another, which not only causes owners to lose a lot of money, but also causes more problems later on.

. In addition, check whether the thickness and diameter of the water pipe meet the contract requirements. There is also a certain standard for the laying of water circuits, which is that the wires must be above the water pipes. The purpose of doing this is to avoid the possibility of water leakage in the water pipe in the future, which will not affect the wires. And all laid wires should be live wires, so it will be more convenient to repair if there are any problems during inspection. The number and orientation of socket devices must also correspond to the design on the drawing, and the number of socket devices on the drawing cannot be less than one, otherwise it will be very troublesome in the future

Even if it can be purchased and used, it still has a significant impact on aesthetics. Sockets must be installed more and used less. Check if the switch can switch sensitively; If there is a dual control switch, check if the dual control switch can be used normally and if the dual open and dual control panel is synchronized; Check if the panel is damaged, if the installation is firm, and if it is tightly sealed with the wall. Use a phase detector to check for correct circuit connections. Ordinary sockets use 10A phase detectors, while air conditioning sockets use 16A phase detectors. The display on the phase discriminator determines whether the circuit connection is correct
