Common sense of water and electricity installation is very important in home decoration. If you buy a poor quality water pipe, it may burst suddenly in use. If it is small, you need to replace the whole ceiling, or if it is large, it will flood the earth. The quality of wires directly affects the service life and safety of home appliances. If the rectification of water circuit is a big expense, the installation of water and electricity cannot be underestimated. Then, the editor will introduce the common sense of water and electricity installation, hoping to help the decoration owners

the common sense of water and electricity installation is very important in home decoration. If you buy a low-quality water pipe, it may burst suddenly in use. If it is small, you need to replace the whole ceiling, and if it is large, it will flood the earth. The quality of wires directly affects the service life and safety of home appliances. If the rectification of water circuit is a big expense, the installation of water and electricity cannot be underestimated. Then, the editor will introduce the common sense of water and electricity installation, hoping to help the decoration owners

1. Slotting of wires and lines

after discussing the power utilization functions and requirements with the owner, the person in charge of construction shall disclose to the electrician and snap the parallel and vertical lines for slotting. Place the switch socket bottom box. Sockets are slotted 40 cm above the ground, hanging air-conditioning sockets are slotted 2.2 m above the ground, and switches are 1.2&mdash above the ground; 1.4m slotting. When the switch socket is installed at the bottom, the horizontal line shall be snapped and slotted. The kitchen and bathroom must be slotted according to the designed function

2. Slotting of water pipes

construction method: snap the line first, and then slotting. The pipeline slotting must be parallel and vertical as required. The pipes that must be laid in parallel must be controlled at a height of 60-90 cm, and the pipes with faucets must be vertical. The depth is controlled at 4 cm. After the trunking is completed, the construction director shall remember the size and position of the slotted pipeline. It is convenient to know the position of the pipeline when installing the sanitary ware in the future

3. Waterway pipeline inspection

waterway pipeline inspection is very important, which is related to the hidden dangers of waterway safety in the future. We usually use the method of pressure test for pipeline inspection. Pressure test is one of the methods to check the leakage of the pipeline. First, bet all the inner wires with the gambling head. Use a pressure gauge to test the water (usually 12 for home decoration). Check all pipes and joints after pressurization. The second method is to open the sluice for two days and two nights after gambling, and check all joints on the third day

4. Water pipeline installation

material requirements, PPR water pipe, aluminum plastic pipe. Three years ago, most users bought aluminum-plastic tubes, and in the past two years, more users have used PPR tubes. The pipes are divided into cold water pipes and hot water pipes. Galvanized iron pipes shall not be used for concealed pipes. First, through the construction drawings, the construction personnel discuss the location and use function of the water area with the owner. Arrange the water and electricity master to discharge and install all taps and water positions. If there are construction drawings, they can be placed according to the construction drawings. If the waterway function of the construction drawing is not in place for a long time, communicate with the owner to increase the waterway use function

5. After the installation of secondary waterproof

waterway pipes, seal all trunking in the toilet with cement and sand. After the trunking and ground are filled with slag, clean the ground and wall again. When the water on the wall and ground is dry, it can be waterproof. It is best to make the wall waterproof one meter high. If there is furniture on the back of the kitchen and bathroom wall, the wall must be full. Play the role of moisture-proof furniture. If the ground needs to be filled with slag, it must be filled with slag after waterproof. If the slag filling is more than 10 cm, cement and sand shall be used to dry mix and fill the slag. Make the secondary waterproof floor and wall together. The waterproof skin made on the ground has been damaged during water and electricity construction, so it must be made again with the wall. The first waterproofing is to ensure that the ground will not leak. After the pipes are installed, the wall and ground shall be made again, so that the ground and wall can be more effectively waterproof

6. Wire and circuit wiring

material requirements, 2.5— Copper core wire of more than 6 square meters and conduit of more than 16mm. Wiring requirements: most electricians do not consider separating strong and weak current, switches, air conditioning sockets and electrical sockets in circuit wiring. Therefore, slotting also saves a large number of processes. The wiring of strong and weak current is required to be separated by 30 cm at the lowest limit. Air conditioning sockets are dedicated to wire grouping of more than 6 square meters, electrical sockets are dedicated to grouping of 4 square meters, and switches are dedicated to grouping of more than 2.5 square meters. The wiring of the air conditioning line group is more than 2 meters from the ground. The ground wiring of electrical wiring group and the top wiring of switch and lighting wiring group wall. The switch socket must be installed horizontally and vertically at the bottom, so that the rear panel will be installed more smoothly. The switch socket of the kitchen must be arranged and installed according to the use function of the kitchen cabinet design. After all the electrical lines are laid out, the construction director shall remember the layout and discharge size of the lines, so as to facilitate the installation of various household accessories in the later stage

editor's summary: that's all for the common sense of hydropower installation. I hope it can help you. If you want to know more about it, you can pay attention to the information
