In home decoration, water and electricity decoration is undoubtedly extremely important. It is an essential element for guaranteeing people's normal life, and it is also a prerequisite for home enjoyment. Therefore, when the architects are building houses, they must install hydropower. It is undeniable that hydropower installation is also the most error-prone part of home decoration. Because most of the hydropower installations are concealed projects, once the accident is extremely difficult to amend, the householder must strictly control the installation of hydropower and try to do it once and for all. Therefore, the water and electricity decoration is very important for the entire home improvement. The following Xiaobian will introduce the household water and electricity installation knowledge as well as the water and electricity installation steps.
Home water installation steps
1. Slotting of pipelines: Construction method, first playing the line, and then grooving. Slotting of pipelines must be parallel lines and vertical lines according to requirements (better if there is a comparison of construction plans for hydropower projects). Pipes that are to be routed in parallel must be controlled at a height of 60-90 centimeters (counting from the ground). Pipes with faucets must be vertical. Depth control is 4 cm. After the slot is opened, the person in charge of the construction shall remember the size and position of the slotted pipeline. It is convenient to know the position of the pipe when installing the sanitaryware.
2, water pipeline installation: material requirements, PPR pipe, aluminum plastic pipe. Most users bought plastic tubes three years ago, and more users use PPR tubes in the past two years. The pipeline is divided into cold water pipes and hot water pipes. Hidden pipes eliminate the use of galvanized iron pipes. First of all, through the construction plan construction personnel and the owner to discuss the location of the nozzle and the use of functions. Arrange the water master to drain and install all taps and water positions. If there is a construction drawing, it can be arranged according to the construction drawing.
3. Water pipeline inspection: Water pipeline inspection is very important, which is related to the future water safety hidden troubles. We usually use pressure testing to do pipeline inspections. Pressure test is one of the ways to check leaks in pipelines. The plug is used to block all internal wires. Use a pressure gauge to suppress (12 pressures for home decoration) test water. Check all pipe fittings after pressure. The second method is to open the floodgates for two days and two nights, and check all joints on the third day. I generally take the former method.
4. Secondary waterproofing: After the water pipeline is installed, all the trunks in the bathroom shall be sealed with cement sand. After the trunking and the ground are dry, clean the floor and the wall again. The water on the wall surface can be used for waterproofing. It is best to make the wall waterproof one meter high. If there is a furniture wall on the back of the kitchen wall, it must be full of walls. Plays a damp-proof role for furniture. If the ground must be filled with slag, it must be waterproofed.
First, the circuit installation
1. It is forbidden to lay the conductor without any protection directly in the wall, in the floor, under the floor or on the ceiling.
2. There must be electric (strong and weak electricity), water supply and drainage design and construction drawings before installation of hydropower.
3, different voltages, different loops, different signal lines are strictly prohibited to wear in the same threading tube.
4, remember not to connect the wire in the threading pipe, that is, if the length of the wire is not enough to be connected, the joint of the wire cannot be in the threading tube. Generally, it should be connected in the switch box, socket, lamp box and other junction boxes.
5, the installation of lighting to be completed after the construction of the paint, the switch equipment to be installed on the phase line, otherwise the switch off, the light off and electrical equipment is still charged, easy to cause electric shocks. If the fixture is a screw base, the center tongue of the screw base should be connected to the control phase.
6, the power system should take appropriate protection measures, grounding protection and zero protection, generally take the ground protection, is strictly prohibited the use of two protective measures.
7, the interface of the circuit should be smooth, the connection board should be firm, it is forbidden that the wire is used to block the conduit.
Second, water installation
1. The hot water tap in the hot and cold taps should be installed on the left side. The electric water heater should have a grounding protection device. When it is used for the first time, the air in the gall bladder should be eliminated. After filling with water, it can be powered on.
2. The drainage pipeline should have a certain slope, and the socket connection is tight to ensure no leakage. The spacing between the brackets and elevators for the fixed pipes is reasonable and firm.
3. The installation of the waterway must be firm and accurate, and the installation position of the bathroom fixture must be precise and firm.
Water Circuit Modification Precautions
1. PVC is a material that the country has banned from using as a water pipe. Never use it. Copper or PPR pipes are recommended.
2, dark trough: that is, all the lines are hidden in the wall inside, these need to open the slot on the wall to put the casing casing, the cost is more expensive.
3, Mingxian: That is to wear the thread inside the casing, hidden in the ceiling or under the floor tiles. The cost is relatively cheap.
4. Waterway design First of all, all equipment related to water must be well thought out, such as water purifiers, water heaters, kitchen treasures, toilets, wash basins, etc., their location, installation methods, and whether they need hot water.
5, in addition to the toilet outside the wash basin, toilet, washing machine and other outlets, it is best to take one out, after the water to the ground, etc. is very convenient.
6, washing machine floor drain is best not to use deep water seal leakage, because the water is too slow to meet the needs of washing machines.
7, strong and weak wires can not be in the same pipeline, there will be interference.
Summary: The above is related to the household water installation knowledge and the installation steps of hydropower. It is for reference only and hopefully helps everyone. If you want to know more related information, you can pay attention to this website information.
