Whether or not the installation of plumbing is qualified is a big issue for decoration. Unqualified installation will cause great problems in the future. It may cause the owners to suffer a lot of losses, and the installation work is not only good When conducting supervision, careful and meticulous acceptance after installation is also an indispensable part. The following Xiaobian tells you some practical tips for plumbing installation and acceptance.

one. Plumbing installation experience

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 spend 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. Simple test method without pressurization but not completely feasible.

● Close the main valve. (ie the water switch in front of the water meter)

● Open the faucet in the room for 20 minutes, make sure that no water is dripped and then close all taps.

● Turn off the water inlet switch of a water storage device such as a toilet tank and a washing machine.

● Open the main valve of the water pipe.

● 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. Pipeline direction: 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.

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 surface musty foaming baseboard or wood floor black and fine bubble water pipe on the top: on the ceiling Wet phenomena or water drops.

two. Plumbing installation acceptance method

The inspection and acceptance of home-installed waterways is based on the acceptance criteria for building water supply. At present, there are no specific express provisions for inspection and acceptance of home-installed waterways. The acceptance methods for ordinary residential houses are:

1. Connect all the hot and cold water supply pipes in the room through a hose to make it a loop. The pipe is filled with water (air) and the total water supply valve of the household is turned off (required to close the valve strictly, otherwise the data is inaccurate, such as the water leakage of the main valve. The other method), using manual or automatic pressure test pressure test pump, the experimental pressure is more than 1.5 times the working pressure, under normal circumstances is 0.8mpa, within 30 minutes, the pressure does not exceed 0.05mpa at the same time check the joints shall not leak qualified . In case of double-storey or multi-storey villas' experimental water pressure, the experiment time can be extended appropriately.

2. The upper and lower water should be reasonable and the pipes should be horizontal and vertical without excessive corners and joints.

3. There is no scratch on the surface of the pipe and the hose is not bent.

4. The outlet elbows of the hot and cold water pipes should be at the same height in the same plane, left hot and right cold, with a distance of 10~15cm and located directly above the drain.

5. The pipeline must be installed firmly. After the water is passed, there should be no jitter, no looseness, and no leakage at the joint.

6. Pressure test should be done on the water pipe, pressure is generally 0.6 MPa, no leakage for 24 hours.

7. The drainage pipe is used for drainage test. The water flow is smooth and there is no water leakage.

8. The new water pipe was used for irrigation experiments, drainage was smooth, and there was no leakage or leakage of the pipe wall.

9. Finish the protection of the finished product pipe to prevent damage caused by man-made foreign objects.
