As we all know, the sewage pipeline is a channel for the clean-up of sewage after daily use. Its role is very important. So, what aspects should we pay attention to when installing it? Here we introduce: sewage pipeline installation procedures and precautions. Sewer installation: 1, the water pipe must be pressurized after installation Pressurization test is generally performed under 1.5 times water pressure, there should be no water leakage in the test 2. Simple test method without pressurization, but it is not completely feasible (1) Close the main valve of the water pipe. (Ie the water meter switch in front of the water meter) (2) Open the faucet in the room for 20 minutes to ensure that no water is dripped and then close all the faucets. (3) Turn off the water inlet switch of a device such as a toilet tank and a washing machine that has a water storage function. (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. 3, the direction of the water pipe It is recommended that the water pipe be 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. What are the precautions for installing a sewer pipe: 1, bathroom water pipes are basically from the roof, because it can reduce the chance of man-made damage, and the interface of the hot and cold pipes, the outlet must be parallel, usually the heat pipe on the left, the cold pipe on the right. In the design, the entire pipeline should be avoided as much as possible. It should be transported away from the circuit as much as possible. The position of the pipe clamp must meet the requirements. Each valve should be installed flat for future use and maintenance. 2, in the installation of hot water pipes need to pay attention to the difference between the inlet and outlet of the water heater, the inlet valve connected to the total valve, outlet pipe connected to the bathroom, after installation, first open the valve to determine whether there is water leakage When the situation occurs, the faucet and shower head can be installed in the bathroom. 3, the bathroom is the darkest in the entire family, the most likely to accumulate moisture, so the ventilation is particularly critical, if you can design a window in the bathroom is the best, if not this condition, in order to prevent the bathroom from mold, tide insects, etc. Phenomenon, in addition to installing the exhaust fan, but also to avoid the "package" phenomenon, many people like to wrap the toilet pipe tightly, and this happens to lead to moisture is not included in the pipe can not spread out, So it will make the moisture in the bathroom more serious. Editor's summary: Sewage pipe installation process and precautions are introduced here, I hope to help you, more information, please pay attention to this site.
