In home renovation, installation of water and electricity is a complex and crucial project. During the decoration process, it will be very inconvenient in the future. Before the owners of the hydropower installation, they must learn more about the installation knowledge and then perform the installation operation according to the hydropower installation specification, so that they can install it better and can also effectively save expenses. Then, the next small series for everyone to introduce home improvement and installation standards for water and electricity installation and water and electricity acceptance considerations.
Home-installed hydropower installation standards
1, kitchen waterway
The transformation of the waterway in the kitchen mainly includes faucets and water heaters. The average family uses a water heater shared by the kitchen and the bathroom. Therefore, when the waterway is reformed, the water heater must be installed so that the location of the hot and cold water pipes can be determined and the waterway can be reconstructed. . When installing, pay attention to the uniform height of the hot and cold water nozzles. The spacing between hot and cold water pipes is 15 cm. This standard must be strictly enforced.
2, bathroom waterway
The content of the transformation of the bathroom waterway is relatively large. The installation positions of the wash basins, toilets, bathtubs, and washing machines must be well thought out in advance. The disposal of floor drains should be in place, otherwise it will cause backwater phenomenon.
3, living room circuit
The wiring lines that need to be installed in the living room include power lines, lighting lines, air conditioning lines, television lines, computer lines, and doorbell lines. The position of the wires needs to be considered in advance and the reserved work should be done. Generally speaking, the doorbell line is reserved on the inside of the door, and the water dispenser, humidifier and other equipment are reserved for the power outlet. In general, the living room should have at least five power lines. mouth. Air-conditioners, set-top boxes and other things that are not in the standby state are best equipped with a switch socket panel so that they can be switched off when not in use and will not waste electricity.
4, bedroom circuit
Bedroom circuit transformation generally includes power lines, lighting lines, air conditioning lines, telephone lines and computer lines. Reserve a power cord at the top of the bedside table and use a 5-hole patch panel with a switch, which can reduce the trouble of not switching on the bedside light. Above the dresser should be reserved power supply connection (hair dryer), in addition to consider there should be reflector lamp above the mirror, plus a switch beside the box, bedroom lighting is best to use dual control switch, one installed in the bedroom door, the other A switch is installed on the upper side of the bedside table or the part where the bedside is easy to operate, so that at night when sleeping, there is no need to get up and turn off the light next to the bedroom door.
5, kitchen, bathroom circuit
There are more appliances used in the kitchen, so when you make circuit changes, you must be clear about which appliances in the kitchen, where the specific location, and where to think about where to reserve wire interface, so that they will not cause trouble to themselves, the bathroom The circuit modification only needs to reserve the line of the whole lighting fixture.
Home-installed water and electricity acceptance considerations
1. Concealed water supply pipelines should be inspected for water. Newly installed water supply pipelines must be pressure tested and there should be no leakage. (The test should be conducted for at least 8 hours after closed irrigation pipe pressure test to maintain the water pressure at least 9KG. If there is decompression, it means there is leakage. This project will be carried out by the general real estate developer.)
2. The drainage pipeline should be temporarily sealed to the original pipeline before construction to prevent debris from entering the pipeline.
3. The installation of the water pipe with the pipe diameter below 25mm shall be installed on the pipe at the corner of the corner, water meter, faucet or angle valve and pipe end 100mm. The installation of the pipe card must be firm.
4. All fittings, valves and pipe connections should be tightly closed, and there should be no leakage. The pipeline has a slope. (Test method: Wipe the joints of all joints, valves and pipes with water towels when using water, see if there is water seepage)
5. The installation of water pipes shall not be close to the power supply, and the spacing between water pipes and gas pipes shall not be less than 50mm.
6, the inlet pipe with hot water PPR pipe, plumbing with PVC pipe. Hot and cold water pipes should be left hot right cold.
7, strong wire tube walks the wall, the weak electric wire tube walks the ground (or the ground strong and weak electric wire tube walks ground, but must separate 300mm above), the water pipe moves away from the wall as far as possible, the trough should be horizontally straight.
8, the dark line laying must be piped, except for the hollow floor (hollow floor with a sheath line), strong and weak electricity can not penetrate the same pipe. The wires inside the tube should be loose.
9. There must be no joints in the wire conduit. After the completion of the water and electricity, the open ends of all switches and sockets must be wrapped with insulating tape to avoid the risk of electric shock.
10, when installing the power socket, should be left zero right phase (fire), above the ground. Fire line into the switch, zero line into the lamp.
11, the same room of power supply, telephone, television and other socket panel should be at the same level elevation, the height difference should be less than 5mm.
12, bathroom socket should be splash-proof.
13, the power socket is generally 300mm from the ground, switching distance from the ground is generally 1400mm, if special needs are handled according to special circumstances (such as wall-mounted air conditioning socket).
14, the lighting wire is 1.5BV, the socket wire is 2.5BV, the ground wire is 2.5BVR, and the air conditioning and special power wire is 4BV. Air conditioning and high-power appliances should be routed separately.
15. The gas pipe (natural gas pipe) must be removed from the pipe, and it must not be sealed. If it needs to be moved, it must be operated by the gas company.
16, wire, hot water pipes, gas pipes should maintain a certain distance between them, shall not be close.
Editor's summary: The home-installed water and electricity installation standards and home-installed water and electricity acceptance notices are introduced here, and we hope to help everyone. If you want to know more related information, you can pay attention to this website information.
