1. It is best to find a professional company to install PP-R pipe, no matter how luxurious and upscale your decoration, if you are not willing to use money in this area, it is not worth it. Frequent crushing or blockage of pipelines will result in tens, hundreds, even incalculable consequences for the prices of the water pipes themselves. 2. Choose a health and environmental protection qualified water supply pipe. At present, most of the residential decoration of the water pipes are mainly divided into: UPVC pipe, PPR pipe, lining PVC galvanized steel pipe, aluminum plastic pipe, copper pipe and stainless steel pipe several categories. 3, must be pressurized after installation test. Pressurization tests are generally performed at 1.5 times the water pressure, and there should be no leakage during the test. 4. Select the laying method of the water supply pipe. The laying of pipelines is divided into wall-mounted and concealed, but which installation method is more suitable for the laying of indoor water supply pipes? Surface installation is the laying of pipelines indoors along walls, beams, columns, ceilings and floor panels. The advantages are low cost, easy installation, maintenance and repair. The disadvantages are due to the gray surface area of ​​the pipes, the generation of condensed water, and so on, affecting the environmental sanitation. Concealed installation is where the pipe is concealed in the room on the ground, under the ceiling or in the tube well, pipe trough, and pipe ditch. The advantage of concealed installation is that the sanitary conditions are good and beautiful. The disadvantage is that the project investment costs are high and construction and maintenance are inconvenient. As it is a hidden project, if the selected drinking water pipe or construction problems cause leakage, the consequences are more serious and the new decoration may be destroyed.
5. A simple test method without pressurization is not completely feasible. 1) Close the water main valve. (ie the water switch in front of the water meter) 2) Open the faucet in the room for 20 minutes, make sure that no water is dripped and then close all the faucets. 3) Close the water inlet switch of the water storage device such as the toilet tank and the washing machine. 4) Open the main valve of the water pipe. 5) Check whether the water meter is moving 20 minutes after opening the main valve, including slow walking. If there is movement, it is leaking. If you don't move around, it may be okay. (If there is a problem with the water meter or micro-permeation of the water pipe, it may be difficult to determine.) Therefore, it is recommended that a hydrostatic test be conducted after the completion of the construction, and the pressure is generally 0.6 MPa for 20-30 minutes. (It's best to see for yourself)
6, the direction of the water pipe: It is recommended that the pipe is safest. The main reason is that most of the waterway reforms go through dark pipes, while the water is characterized by low water flow. If the pipeline goes underground, it is difficult to find water leakage in time. Only if the water is diffused into the Jinshan or the floor is deformed and leaked downstairs, water leakage will be discovered, and it is difficult to detect leaks due to buried pipes. At this time, the huge losses are even more irreversible. They have even seriously affected friendly neighborhood relations; if the water pipes are at the top, the cost of water reform may be higher, but as a long-term investment, it is worthwhile. When the water pipe is at the top, even if it leaks, it can be discovered in time and is easy to overhaul. The loss is also small. 7, in daily life, if you find the following situation, please check the relevant pipeline as soon as possible. When the water pipe goes underground: 1) The surface of the wall paint is mouldy and blisters. 2) The baseboard or wooden floor is black and the surface appears fine. When the water pipe goes to the top: 1) There is a dampness or water drop on the roof. 2) There is dampness or water leakage from the wall of the walkway wall. 8, from the professional perspective of the installation of water pipes, it is recommended that the owner of the house decoration, the best installation of water pipes in place. The wall, the ground is broken, relatively easy to repair, but the water pipe problems, especially the hidden pipe problems, I am afraid that Not only is your own economic loss and troubles, but it is more likely to cause you to claim compensation from you for the loss and trouble of the downstairs tenants. The frequent occurrence of flooding is caused by the leakage of water pipes. Therefore, the water pipe problem must not be saved.
