Hydropower projects, which we often call hidden projects, are buried in walls, floors or ceilings after completion, and we can't tell from the surface whether there is a problem. However, once something goes wrong and the problem is exposed, it is possible to flood the golden mountain, and the difficulty and high cost of maintenance are high, which makes many owners very headache.
In fact, we have to go back to the root of the problem, control the construction quality at the beginning of the water and electricity decoration, and strictly follow the standards, then there will be no big problems in the later stage!
So, what are the formal water and electricity decoration standards? Today, the editor will tell you about the detailed construction standards in combination with pictures and texts?
1. Professional tools are required for hydropower grooving, and the depth of grooving cannot exceed 3.5cm. If the groove is opened too deeply, it will destroy the stability of the floor.
2. Air conditioners, refrigerators, water heaters and other major strategy appliances should be set up with independent lines, if mixed with other electrical appliances, there will be tripping.
3. It must not be grooved horizontally, which will seriously affect the stability of the wall structure and easily cause collapse.
4. The wiring must use PVC line pipes specified in national standards, and all lines cannot be exposed to ensure that the trunking is not damaged.
5. The wires in a conduit should not be larger than 3, and the cross-section of the wire should not exceed 40% of the conduit section to avoid knotting the wire and affecting the heat dissipation.
6. The layout of water and electricity should follow the principle of horizontal and vertical to reduce loss and clutter, and the key is to facilitate maintenance.
7. The distance between the wire pipes is 2cm, which is fixed with a professional tube card, and the distance between the two pipe cards is 70cm.
8. Keep a distance of more than 20cm between strong and weak electricity. When the strong and weak electricity cross, whether to pack tin foil depends on the choice of the master, in fact, separate line pipes, mutual interference is negligible.

9. When the water and power pipes meet, follow the principle of electricity on and underwater, even if the water pipe bursts in the future, it will not affect the use of the circuit.
10. All thread ends in the whole house need to be wrapped and placed in the cassette, and the thread should be threaded with crystal heads or crimping caps, not cloth.
11. When the circuit is reconstructed, the position of the socket installation should leave at least 15cm or more of the wire end, and the position of the lamp installation should leave at least 50cm or more of the wire end, so as to facilitate the installation of panels and lighting in the future.
12. The circuit of the bathroom is as far as possible to go to the top without going to the ground, the bathroom floor is often flooded and easy to damage the circuit, and it is easy to find that there is a problem if you go to the top.
13. If the water pipe goes to the top, it must be fixed with a pipe card every 1.5m to warp the water pipe when it passes through the pressure vibration.
14. After the construction of the waterway, remember to protect the gate with a professional protective sleeve to prevent cement residues from falling into it and blocking the pipeline in the later construction.
15. When wiring water and electricity, we must avoid the exhaust pipe of the water heater to prevent long-term high temperature erosion of the waterproof electric pipeline, which will affect the service life.
