1. direct sawing.

This method will certainly damage one of the pe fitting. After cutting through the 90 degree elbow with cleanout opening and digging out the bonding pipe in the 90 degree elbow with cleanout opening, the 90 degree elbow with cleanout pipe is no different from the previous one. Of course, it can be reused, but it is hard to say whether the other downpipe can continue to be used.

2. use the physical characteristics of thermal expansion and cold contraction.

Glue will become less sticky when it is hot, so you can use boiling water to heat the joint of two pvc pipe fittings for a few minutes, and then pull out the two pvc pipe fittings connected when they are hot. This method consumes a lot of hot water, but it will not damage the two pvc pipe fittings, and will not affect the later secondary utilization.

3.Use the blower. However, the heating of the blower is usually only partial, so the effect may not be so good as that of hot water. This method is also for reference only.

4.This is a professional method, which is to use PVC glue brush on the inner wall of the pvc fitting, ignite the fire for about 10 seconds, and then use a screwdriver to quickly pry out the inner wall, so that the two pvc pipe fittings can be separated, and the pvc fitting can also be reused.

5.Use tools. First prepare the tools: a hammer, a small slotted screwdriver and a pair of pointed nose pliers. It is easy to damage the pipe fittings by using a slotted screwdriver at the connection of the pipe fittings and beating the screwdriver with a hammer, which can not meet the requirements of secondary utilization at all.
