Installation suggestion
1. It is best to find a professional company to install PP-R pipe. No matter how luxurious and upscale your decoration is, if you are not willing to use money in this area, it is not worthwhile. Frequent crushing or blockage of pipelines will result in tens, hundreds, even incalculable consequences for the prices of the water pipes themselves.
2. The boost test must be performed after installation. Pressurization tests are generally performed at 1.5 times the water pressure, and there should be no leakage during the test.
3. 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 inside the room for 20 minutes to ensure that no water is dripped and then close all taps.
3) Turn off the water inlet switch of the device, such as a toilet tank and a 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. Generally, 8 kg of pressure will be applied for 20-30 minutes. (It's best to see for yourself)
4. Direction of water pipes: It is recommended that the pipes be the 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.
5. In daily life, if you find the following situation, please check the relevant pipeline as soon as possible: Water pipe to go underground: Wall paint must be moulded out of foam Baseboard or wood floor black and fine foam pipe on the surface go Top: Overcast on the Roof Wet phenomenon or water drops
Slots should pay attention to the problem
After the water is heated by the water heater, it is recycled into the vegetable basin, the basin, and the water is not hot after the shower. Many people are skeptical that there is a problem with the water heater, water heater maintenance workers say that the gas pressure is small, and so on. In fact, we have all overlooked the problem that there are problems in the installation of water pipes. In the process of installing water pipes, it is very beautiful to bury the pipes in the walls by grooving the walls inside the wall. However, some people do not want to open the wall slots too wide for the sake of effort, especially for reinforced concrete walls. Slotting is quite difficult, so less slotting results in less slotting and the hot and cold water pipes squeeze very tightly. It is not right for hot and cold water pipes to be close together. After testing two pipes close together for 20 meters long, hot and cold water are in circulation. The temperature of the water from the water heater is 80 degrees to the end is 70 degrees, starting 55 minutes before the end of 10 minutes. When the hot and cold water pipes are separated, its temperature is 80-78 degrees. This test can explain the problem. Take a diameter of 20 (usually refers to the quadrant) of the water pipe slot should be (upper end 1CM + hot water pipe 2CM + 2CM + cold water pipe 2CM + lower 1CM) a total of 8CM two water pipes in the minimum not less than 2CM.
