A, how to check and accept water and electricity:
1. How to check and accept the water, electricity and circuit: the depth of the circuit slot on the room wall should be 1.5 times the pipe diameter, and the conduit should be fixed at the corner with a pipe bender, with a length of 200mm. There should be a lock nut at the joint between the catheter and the catheter, and the joint should be glued firmly.
2. How to check and accept the water and electricity box: No matter the distance between the circuit box and the strong current and weak current is 5cm, the distance between the boxes is 150-200mm in the case of strong current and weak current.
3. How to check the water and electricity, and check the floor heating: When we carry out the water and electricity transformation of the house, the construction personnel should check whether the floor heating is damaged with the pressure of 6pa. If you want to change the floor heating structure, you need to consult professionals before deciding on the construction plan.
4. How to check and accept the water and electricity, and transform the water and electricity in the bathroom: there are many water pipes in the bathroom, and the standards of each water pipe are different. 1, water heater pipe: distance from the ground 1.8m, distance between hot and cold pipes 10cm. 2. Shower water pipe: From the ground, the outlet should be at least 1.2m, and the distance from the wall should be1mm. The upward water pipe connecting the outlet can only be fixed at the distance of1m.. 3.

Second, the water and electricity acceptance matters needing attention:
1, when we check the water and electricity, we are now looking at the certificate of electrical products, whether it meets the relevant standards of qualified products. These can refer to domestic product standards.
2. The laying of wires requires the use of flame-retardant concealed pipes, and the wires cannot be knotted and kinked in the pipes, which may easily lead to short circuits.
3, we need to pay attention to check whether the wire is directly buried in the plaster layer, which should be prohibited.
4. The installation of the composite wire shall be specified as "live wire enters the switch, and zero wire enters the lamp holder", and the connection of the socket shall conform to the provisions of "left zero and right fire is grounded on the top".
5. Electrical appliances used by RTVU, such as air conditioners and high-power appliances, should be managed separately, and the wires should be 4 square millimeters.
6. Household lines should be installed separately, and power lines, TV lines and telephone lines should not be installed in the same pipeline.
7, household power switch, socket installation is firm, the position is correct, the cover plate is correct, close to the wall, seamless around.
8. After the installation of kitchen gas and electrical engineering is completed, electrical power supply, lighting test and switch control should be carried out.
9. Electrical pipes should be installed in strict accordance with your requirements. It is forbidden to use elbows at the corners of electrical pipelines, and springs must be used to penetrate the inner bends of the pipelines. In general, the number of elbows shall not exceed 13.
10. The colors of wires in the room should also conform to the specifications, which should be: red, blue, double-line color and white.
