Is there a trick to sealing threaded PVC??
HI All,
I replumbed my filter and pump today. All is well but I have a few very slow leaks at some of the threaded joints (a thimble full every few hours) I tried everything to fix these things up to and including using 10 wraps of teflon tape to no avail. Is there a liquid pipe compound I could use that may give better results? I've taken it apart four times now and still no luck. It's not a big leak but frustrating.
Thanks,
Joe

Ok, 3 things may be going on:
1) your theads on the fittings may be damaged. Then they leak.
2) You are using the tape wrong. It should be pulled very tightly around the threads and go in so the tape it pulled tighter, not bunching up.
3) You aren't tightening the fittings enough. Did you may sure to use only Schedule 40 fittings? Some have longer thread areas allowing you to have more sealing.
I hope this helps.
There is a liquid teflon called plumber's joint compound. It used to be called Plumber's Dope, and the tape was Tape Dope. No foolin'!

Thanks Carl,
I tightened them down quite a bit and used the tape properly. I'm going to give the Permatex #2 a try tomorrow, let it cure for 4 hours and see what happens. Pentair says it's OK to use.......

i've used permatex 2 as well and it works pretty slick. one thing to watch from my experience this year is if you put it on 0 rings for example (i.e. behind it) it creates this thick gunk that doesn't seal well in combination with the o-rings.

There is a product that is called plumbers goop that you can put on to stop the leak.

I think I'll try this.

seems safe. Hopefully it works well.

:cool:
I was looking at the install last night and while I'm not a plumber, it looks WAY better than what the PB did. I also used all hard PVC, no flex tube.
Once I get all the minor leaks sorted, I'm going to hook up my liquidator.

I used Great White pipe dope recently and it worked well. I did have to tighten one joint a half turn to stop a very slow seep.
