How to dissassemble PVC pipe connections"?

Question

I am trying to replace a electric anti-siphon valve on my sprinkler system but dont know how to dissasseble a PVC cemented coupling without sawing it?

Answer 1

There is no way that I know of. The best thing to do is cut it with enough room to put a new coupling and a piece of pipe to fill the gap. there are things called slip fix that will slide into place of the piece that you cut out. Try that or talk to a sprinkler person at a hardware store.

Answer 2

The saw is the only way. That cement actually fuses the pipe to the coupler, so there is no going back. When you cut it, be sure to give yourself plenty of pipe to work with or you will be doing more plumbing than you hoped for.

Answer 3

You'll have to saw it. Be sure to saw it close to the existing fitting as possible to save enough pipe to re-glue it back together. Good Luck

Answer 4

i did it once by accident. i was trying to get a 1/8 inch of play out of an existing pipe. i had a pipe wrench on a union exerting pressure when it poped. came off clean too. else saw it and then add a sleve to extend it.

Answer 5

Actually, there are things that can unweld the cement attachment but as they are nasty chemicals, and considering it is SO EASY to saw and re-cement. Why would you want to?

Really- sawing and then cementing it back in place is VERY easy and you can do it yourself.

Good luck.
