1. First, clean the foreign objects in the parts to be connected with the raw material belt;

2. Pay attention to the winding direction. Take the angle valve as an example. When the angle valve is screwed into the internal thread on the wall, it rotates clockwise to the right. Then, the direction of winding the scrap tape on the angle valve is counterclockwise to the left, so that the angle valve will become tighter and tighter and will not loosen.

3. Unfold the sealant tape, press one end on the external thread of the water pipe with your fingers, and then wind the other end on the external thread (note that the winding direction should be clockwise), and at the same time stretch hard to wind all the external threads evenly, and don't wind them too many times. When installing the faucet, it is best to use a wrench, which is not tight by hand, and it is easier to screw it to the desired position with a wrench.

Matters needing attention in decorating and laying water pipes

1, calculate the approximate dosage.

Before installing water pipes, estimate the consumption before purchasing materials, so as to avoid waste or lack of materials and affect the installation process.

Step 2 use new water pipes

If it is a second-hand house or an old house, the old water pipes are often damaged. Don't hesitate to change them decisively. After the water pipe is installed, some parts are inconvenient to replace, so they are all replaced with new ones to ensure safety.

3. Inspection of water pipes and fittings

Before installation, check the water pipes and their fittings to see if there are any problems such as damage and leakage. The connection between water pipes and fittings must be correct and firm, and installed after testing.

4. Water pipe direction

It is suggested that the water pipe roof is the safest, mainly because most water pipes are hidden, and the characteristic of water is that water flows downwards. If the pipeline goes underground, it is difficult to find water leakage in time, and it will only be found when the water overflows Jinshan or the floor is deformed and leaks downstairs. Moreover, because the water pipe is hidden, it is difficult to find water leakage, so the huge loss is irreparable and even seriously affects friendly neighborhood relations. If the water pipe reaches the top, the cost of water reform may be higher, but it is still worthwhile as a long-term investment. Even if the water pipe leaks, it can be found in time, with convenient maintenance and less loss.

Step 5 test the water pipe

After the water pipe is installed, test whether there is water leakage. Before the test, turn off the main valve of the water pipe, and then turn on all the faucets to see if the water meter will move. If there is, it means there is water leakage. If the water meter does not move, the water pipe installation is qualified. It is better to test the water pipe for about half an hour.
