How to Solvent Weld PVC Pipe and Fittings

Step 5PUSH!

PUSH!
The motion for solvent welding two parts together is pushing in while simultaneously twisting 90 degrees. This makes a more airtight joint. If you push straight in, there is a slight chance that you could have a channel run straight through the joint and allow air or water to escape.

With small parts, this is easy.

With large fittings, it's often more like, "EEERGGGAAARRRRDAMNIT#@$~!STUPIDPIECEOF$%&~!!!!." If you've working with 4in or more, I'd even suggest having a friend help.

Once you push and twist the parts together, hold them like that for about 10-30 seconds (longer for larger parts). You don't have to hulk-crush them the whole time, you are just making sure that the pieces don't back out. PVC slip connections are tapered, which means that sometimes, if you were to push it together and just let go, the inner piece would just slight right out, which is extremely frustrating.

After about 10-30 seconds the bond should be strong enough to keep the part from jumping out.
