Living for a long time, the water and electricity facilities in the home will inevitably be a problem. Under normal circumstances, everyone will ask the decoration company or professional maintenance personnel to do it, but sometimes it is difficult to avoid the place where they do not trust, not only to spend more money may also have hidden dangers. Therefore, it is very necessary for us to have a certain understanding of the family's knowledge of water and electricity maintenance and to avoid the decoration company cutting corners. Below I have put together some related knowledge about what family water and power maintenance mainly includes, as well as household water and electricity maintenance precautions. I hope to help everyone.
I. What are the major household hydropower maintenance?
1. Installation and modification of water pipelines
On the water pipe: water pipeline rupture treatment, galvanized pipe transformation and replacement, aluminum molding pipe, composite pipe, ppr pipe installation, maintenance and replacement.
Under the water pipe: pvc pipe maintenance, repair, replacement, cast iron pipe repair, replacement, single-story sewer and the main floor of the sewer installation and maintenance.
Appliances: leaking toilets, leaking valves, leaking basins, installing booster pumps, repairing leaks in toilets, replacing valves, replacing water tank accessories, basins, triangle valves, faucets, etc.
2, circuit transformation and design, installation and maintenance
Home strong electric circuit: home circuit tripping and other normal fault repair and maintenance, various lighting switches, metal pendants installation, home circuit aging transformation.
Heavy-duty equipment circuit: the transformation of professional circuit wires, maintenance, repair of factory professional electrical appliances.
Smart lines, weak maintenance: home network cable installation, network room installation, network integrated wiring.
Second, household water maintenance precautions
1, the wire is not insulated. During the construction, the wire is directly fed into the wall. The wire is not covered with an insulating tube and the wire connector is directly exposed. There are hidden dangers: You can cause a short circuit due to a broken wire for some reason. Once the wire is disconnected and the wire cannot be changed, you can only knock the wall. The correct operation should be put on the insulating sleeve, the joint should not be exposed, and no joints are allowed between the distribution boxes.
2, the wire is not separated. All wires have a color. There are hidden dangers: once the line is in trouble, the line of discordance is detected again. The correct operation should be the bottom box wiring cloth with a different logo dressing, the fire line should use red, green, yellow, zero line is appropriate to use blue, grounding two-color line.
3, repeat the wiring. A lot of repeated wiring, waste of materials, financial resources and material resources. There are hidden dangers: Once the lines are aging, it is difficult to detect them in a chaotic network. Normal operation should not exceed 40% of the capacity of the pipe. The line of the same direction can be worn in one pipe, and the separation between strong and weak electricity should be conducted. The distance between parallel pipes should not be less than 50cm.
4, the length is not enough without connection accessories. Because the length of the insulation tube is not enough, no connection fittings are placed at the corners, and a section is exposed at the intersection with the junction box. There are hidden dangers: there is a danger of leakage. The standard operation should have a joint connection between the nozzle and the junction box.
5, strong and weak electricity placed together: to save labor and labor, strong and weak electricity placed in a tube. There are hidden dangers: the phone, the Internet will have an impact, there is the risk of fire. Normative operations should be strong and weak to separate wires.
Third, household water and electricity maintenance knowledge
1. Drainage facilities
Usually, during the renovation process, the equipments in the kitchen and bathroom are relatively more moved and replaced. When the construction is changing the water pipe, the water meter should be high in the easy-to-view and easy-to-maintain place. During the installation, pay attention to the pipe installation and fixing. Whether it is firm or not, and at the same time, the thickness of the decorative wall should be taken into account, so that the maintenance and disassembly of the pipeline can be performed later.
2. Natural gas and gas
When doing natural gas and gas reform and maintenance, we must ask the construction personnel to do a good air pressure test, and then put it into use, and the construction of the gas meter and management should not be installed in a hidden place, otherwise it is not convenient to view, it can not Promptly find problems such as leaking pipes.
3, electrical
When doing electrical renovation and maintenance, the design of the original line should be considered. Lighting, sockets, air conditioning, etc. should be the best way to choose the way of branch control, and reasonably distribute the load of the line.
4, plumbing
When the water heating system is reformed, the indoor riser cannot be changed. If unauthorized changes are made, it will affect the use of the entire system, but the position of the branch pipe and the position of the radiator can be changed. It should be noted that the water pressure must be passed after the transformation. The test verifies that it is tight and then puts it into use.
Editor's summary: Hydropower maintenance is of utmost importance. We must select a regular decoration team and professional construction personnel. We must also do a good job in related supervision work during construction to reduce the occurrence of hidden dangers. We hope that the above knowledge will help you. When there is a problem with the water and electricity in your home, you will not be deceived when it is handled by maintenance personnel because you are a layman. Xiaobian's introduction is here.
