Why does the PVC water pipe joint leak? If the toilet sewer pipe uses a PVC water pipe, you can buy a PVC water pipe to connect it yourself when there is water leakage. In addition, you can also buy waterproof tape to repair the sewer pipe, and then apply it with mortar waterproofing agent and cement. What are the main reasons? The glue is not uniform, or the surface is not wiped clean, or the water is passed through soon after it is stuck, because the glue cures slowly in winter, which will cause water leakage. If the fixed phone is not good, you can re-touch some glue after unplugging it, or touch some glue at the mouth to see if it can be blocked.
