Water and electricity installation plays a decisive role 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, and if it is large, it will flood the ground. The quality of wires directly affects the service life and safety of home appliances. If the rectification of water circuit is a big expense. Water and electricity installation is so important, so what is the knowledge of water and electricity decoration, including several aspects? Next, follow Xiaobian to have a look

water and electricity installation plays a decisive role 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, and if it is large, it will flood the ground. The quality of wires directly affects the service life and safety of home appliances. If the rectification of water circuit is a big expense. Water and electricity installation is so important, so what is the knowledge of water and electricity decoration, including several aspects? Next, follow Xiaobian to have a look

water pipeline installation of hydropower decoration knowledge

water pipeline installation: material requirements, PPR 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 of water and electricity installation, 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

water pipeline inspection of hydropower decoration knowledge

water pipeline inspection: water pipeline inspection is very important, which is related to the hidden dangers of water pipeline 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. I usually take the previous method

water pipe slotting of hydropower decoration knowledge

water pipe slotting: construction method, snap the line first, and then slot. The pipeline slotting must be parallel and vertical lines as required (if there is a water and electricity construction drawing, it is better to compare with the construction drawing). The pipes that must be laid in parallel must be controlled at a height of 60-90 cm (calculated from the ground), 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

secondary waterproofing of water and electricity decoration knowledge

secondary waterproofing: after the installation of 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. (there must be a friend here who wants to ask me why I have to do waterproof once when the ground enters the site.). 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

wire and circuit wiring of hydropower decoration knowledge

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 away 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

wiring slotting of water and electricity decoration knowledge

wiring slotting: after discussing the electrical functions and requirements with the owner, the construction director 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

the above is the introduction of water and electricity decoration knowledge. I hope it will be helpful for you to do water and electricity. For more information about hydropower, please continue to follow the information
