Article Introduction
Whether you’ve made a mistake or are replacing an old fixture, sometimes you need to untie polyvinyl chloride (PVC) pipes and fittings. However, this is impossible because there is nothing that can dissolve the glue between PVC pipes, but fortunately, there is a solution when it comes to dealing with stubborn PVC pipe glue.
Read on to learn how to remove PVC pipes and fittings while they are still connected !
Understanding PVC Adhesives
Before delving into the process of ungluing PVC pipe, it’s important to understand the nature of PVC adhesives. PVC glue, also known as PVC cement, is a solvent-based adhesive that works by melting the surface of the PVC pipe and fitting. When the solvent evaporates, the two pieces of PVC fuse together, creating a bond that is often stronger than the pipe itself.
Methods for removing glued together PVC pipe elbows
Method 1
The first is relatively simple and crude, that is, direct sawing. This method will certainly damage one of the PVC pipe fittings, along the three-way saw after digging out the three-way pipe, the three-way pipe is as new as before, of course, can be reused, but the other sewer can continue to use, it is difficult to say.
Method 2
The second is to use the physical properties of thermal expansion and contraction. Everyone knows that glue will become less viscous when heated, so you can pour hot water at the junction of the two fittings for a few minutes, and then take advantage of the heat to pull the two fittings together. This method consumes a lot of hot water, but it will not destroy the two pipe fittings, and will not affect the later secondary utilization.
Method 3
The third one is actually similar to the second one, just using a hair dryer. But the heating of the blower is usually only local, so it may not be as good as hot water. This method is for reference only.
Method 4
Fourth, this is a more professional method, is the use of PVC glue brush in the inner wall of the pipe, ignition burning about 10 seconds, and then quickly pry out the inner wall with a word scraper, so that the two pipes can be separated, and the pipe can be used again.
Method 5
The fifth one may be solved by brute force. First, get the tools: a hammer, a screwdriver with a small head and a sharp nose pliers. Separate two connection pipe handling methods, you can imagine the picture. Feel this kind of not only violence, the operation process is also easy to destroy pipe fittings, can not meet the requirements of secondary utilization. Therefore, we should consider whether this violent method is appropriate.
Summarize
With the right tools and methods, you can “untie” PVC pipes. The key is to follow these tips and know which methods to avoid. Ungluing a PVC pipe is a challenging but achievable task, Once that’s done, gluing PVC pipe in the fashion you want is a cinch!
