Most people know nothing about water valve maintenance, so here is just to share our experience, here only applies to PVC-U materials such as ball valves and water pipes.

 

The first is the preparation work. You need a brand new PVC-U ball valve (about five yuan), a small can of PVC-U glue (about ten yuan), a hand saw and a pair of gloves.

If you do not have a hand saw during maintenance, use a knife instead. The efficiency is very low. Although it is finally cut open, it is recommended to use a hand saw to improve work efficiency.

 

The first is to close the main valve, and then start cutting the water pipe along both sides of the broken ball valve. However, if the hand saw is used, the cut surface is very smooth, which is more conducive to the subsequent bonding.

 

The badly cut ball valve can be thrown away and wipe the water around the water pipe. Some people may ask the question that the cut tube will be shorter if it is glued together. Although the upper part of my water pipe is fixed on the wall here, it can be pulled up and down, and generally it can be pulled down. If it is not feasible, you need to buy another water pipe to connect or replace the whole water pipe.

 

The next step is to apply glue. It is recommended to wear gloves. You can insert the tube into the ball valve before applying glue, and then draw a line with a pencil to know how much glue you need to apply. After painting on the water pipe, insert the ball valve, and then wipe off the glue flowing out with paper.

 

That's it. It is recommended not to pass the water immediately and let it pass overnight. The whole process is relatively simple. The cost is also very low.
