Waterway transformation steps

>>>Links: Summary of problems with waterway reconstruction

1. According to the owner and design requirements, the water pipes should be buried as far as possible. Reasonably design water supply and drainage of easily forgotten water appliances such as washing machines and mop pools. In line with national standards. The materials, specifications, models and origins of pipelines, sanitary ware and valves shall meet the design and contract requirements. The main materials and equipment shall have a certificate of conformity.
2. The pipeline shall be installed horizontally and vertically, laid firmly, and the slope shall meet the requirements. The installation of the water pipe shall not be close to the power supply, and the distance between the water pipe and the gas pipe is recommended to be not less than 50mm. Water inlet pipe, hot water pipe, gas pipe, tight fitting joints, anti-rust paint with hemp wire, cleaned after connection. Buried joints must not use raw tape. The pipe thread connection should have exposed threads at its connection, and the pipe must be more than five teeth.
3. When installing the pipe, install the pipe with an outside diameter of 25mm or less. Pipes shall be installed at the corners, water meters, faucets or angle valves, and pipe ends at 100mm. The pipe card must be installed securely. The tube must be painted with silver powder or paint before finishing.
4. After the water pipes are installed, the hot and cold water is concatenated and pressure test is performed (standard: 0.8MP for galvanized pipes, 0.3-0.5MP for aluminum-plastic composite pipes, 0.8-1MP for PPR pipes, and the pressure is kept for ten minutes without leakage; the air pressure does not decrease. Party is qualified.) The sewer pipe should be inspected for leaks. The gas pipe should be vented for leak detection (check with soap solution). Only after the inspection is completed can cement be filled. Toilets, wash basins, sinks, etc. Wall pipe fittings should be installed behind the triangle pressure relief valve can be connected to water.
5. When installing kitchen and sanitary pipes, the size of the pipe at the wall should take into account the final size of the wall tile after it is attached, that is, the thickness of the wall tile is taken into consideration in advance. When designing the water pipe, the installation position of the faucet and the arrangement of the water should be taken into account. At the same time pay attention to whether the location of the washing machine power socket is appropriate, and the fittings must not be damaged during the installation process. If there is any damage, it must be replaced no matter if leakage or leakage occurs.


6. When the hot and cold water pipes are installed parallelly above and below, the hot water pipes should be above the cold water pipes; when installed in parallel, the hot water pipes should be on the left side of the cold water pipes. When installing hot and cold taps on sanitary appliances, hot taps should be mounted on the left side of the face.
7. The mixing faucet on the tub should be installed in the middle of the bathtub (the size of the bathtub should be determined when the tubing is embedded). The center distance of the faucet is 150-200.
