How to separate PVC pipe fittings?

Publish Time: 2019-07-26     Origin: Site

When the PVC pipe fittings are connected, glue is called a solvent weld. This glue is almost impossible to separate the pipes after you connect the PVC fittings. It is not normal glue, it can melt the plastic and then melt and connect. After the connection, the original hardness will be restored, and the two will be overlapped. If you want to separate it, you need to cut it off. So if the joint is broken, the pipe union cuts the joint and reinstalls the joint. But many people want to know how to separate the glued PVC pipe fittings parts?

Separate the glue before it hardens


The glue used to connect the PVC pipe fittings is very easy to dry. The drying time can be from one minute to five minutes depending on the pipe diameter. However, if you want to be completely fixed, it takes an hour. But it is not so easy to separate the dry glue, and the chances of success can be very small. If you pull it off easily, your pipe will be easily damaged. So you need to pull and twist with a lot of effort. If there is an error when bonding the water pipe, first turn on the water and let the water pressure blow the pipe open. Some people will worry about whether the water will spew out. Actually, it will not. Because after a few minutes of bonding, the joint can withstand normal water pressure and will not leak or separate.

 

Heating and softening pipe fittings


When you have fully bonded the fixed PVC fittings, you can heat it to soften it, so pointing the blower or hot air gun at the joint may soften it enough for you to pull them apart. The heat at the joint is maintained when the pipe is pulled stably to separate them. However, if you use enough heat to distort the pipe, you cannot reuse it.

 

Cut open reinstall connection

 

If your glue is completely fixed and you are not using the heating method to separate the PVC fittings, then you must not easily disconnect them. At this point you need to cut it and separate its joints. You can cut it with a hacksaw or a PVC cutter, and once the cut is complete, you can't just install it back. You need to narrow the gap left by the missing joint by sticking a small length of pipe to the pipe you want to connect. Because you need to install a coupling to do this (and the coupling requires space), it is best to remove the slit three to four inches from the joint when disassembling. This leaves a wider, more manageable gap.

You can separate or sever the joints that were not properly assembled first. Perhaps the installer is using insufficient glue or failing to fully secure the pipe. This joint may leak, which is a possible cause of re-bonding. To separate the pipe, align the edge of the chisel with the edge of the female part of the joint and tap the chisel with a hammer. If you detect motion, you are on the right track, so keep clicking. If there is no movement, it is best to stop because continuing to hit the chisel will damage the pipe.

 

Conclusion

 

When you install PVC pipe fittings, it is best to find a professional plumber. This is not a simple job. If there is a mistake, the PVC pipe fittings are not so easy to disassemble. Really not, you can understand the methods in the article, I hope to help you.
