Water pipe installation skills and methods What are the precautions for water pipe installation?

Hydropower installation is the foundation of home improvement. In order to reduce the frequency of later maintenance, the owner must carefully check the water and electricity. Take water pipes for example, there are many installation skills, and owners should know a little to prevent workers from cutting corners. Today, Bian Xiao will talk to you about the skills and methods of water pipe installation, and what are the problems in water pipe installation, hoping to help you.

A, water pipe installation skills and methods

1, pipeline groove and bracket retest

Before the installation of water pipes, the trench must be retested to see whether the supports meet the elevation, slope and direction of pipe installation. Whether the bracket spacing meets the requirements of drawings and relevant specifications. At the same time, the technological needs of venting and pipeline operation should be considered.

2. Arrangement order

In daily life, the general principle of installing hot and cold water pipes is "hot left and cold right". Don't violate this rule. Generally, the faucet is selected first. If there are mistakes, they need to be corrected in time so as not to affect life.

3. Choose a 45-degree elbow

In the process of installing water pipes, in order not to cause sewage blockage and sewage backflow, pipe fittings such as 45-degree elbow and 45-degree oblique tee can be used to arrange the sewage direction. Remember, try not to use a 90-degree elbow.

Second, what are the precautions for water pipe installation?

1, pay attention to the water pipe material.

Because there are certain standards for burying hot and cold water pipes, they also need to be distinguished in color. Cold water pipes, generally buy stainless steel pipes with blue straight lines outside; Hot water pipes are stainless steel pipes with red lines on the outside. The wall thickness of hot and cold water pipes is different. Cold water pipes cannot be used as hot water pipes, and the temperature resistance of cold water pipes cannot exceed 90 degrees Celsius. If they work in hot water for a long time, they will soon age and crack.

2, pay attention to the wall groove

In the process of installing water pipes, it is very beautiful to bury the water pipes in the wall, but some installers don't want to open the wall slots too big in order to save labor, especially now there are many reinforced concrete walls, and it is quite difficult to slot, so they can slot less and squeeze the hot and cold water pipes tightly. The owner should pay special attention to the fact that the cold and hot water pipes are not close together, which will lead to the phenomenon that the water is not hot after the water heater heats the basin and shower.

3. Pay attention to the pressure test

After all water pipes are installed, be sure to carry out pressure test. The pressurization test is generally carried out under the condition of 1.5 times of water pressure, and there should be no water leakage in the test. If there is water leakage, the owner shall immediately notify the workers to repair it.

These are the skills and methods of water pipe installation that Bian Xiao shared for you, as well as the information about matters needing attention in water pipe installation. I hope it will help you.
