The pvc pipe manufacturer introduced that you should first turn off the tap water valve, then observe the leaking point, and check what is the condition of the crack. Secondly, observe the severity of the crack. If there is only a crack, you can go to the hardware store at the door to buy it for repairing plastic pipes. For broken glue, be careful not to use glue casually, and use professional glue that will not pollute the water quality.
If the rupture is large, like a hard injury caused by a collision, if it is confirmed that it cannot be sealed with glue, you can measure the diameter of the pipe, go to the hardware store to buy a joint that just fits both ends, and cut off the leak. Once the two ends are connected with glue, it will be OK. After observation, it is found that the plastic pipe cracks have filled the entire section, there is no need to repair it locally.
If you find that the water pipe has been broken, and water is spraying out, and water is splashing everywhere, don’t panic at this time, you should close the tap water valve at home in time, and after closing the valve, clean the water near the electrical appliance or electrical outlet in time , To prevent electric shock or damage to electrical appliances, and then find a repairman to repair in time.
