What should I do if the root of the roof exhaust pipe leaks+
Is the pipe broken, or is one side of the pipe leaking downwards? If the pipeline leaks, first clean up the garbage and cement around the pipe hole, stick the pipeline around the pipeline and make a circle with a width of 3 to 5 cm. Then prepare a short pipe with the same diameter as the pipeline and a length of 5 to 20 cm, cut it vertically into an open ring, brush a circle of PVC drainage pipe glue at the height of the trachea hole, cover the hole with the short pipe, and sprinkle water around the pipe trench after the glue dries. If the pipeline does not leak, as long as the surrounding grooves are properly deepened, it can be leveled by blocking the king.
