Is there a trick to sealing threaded PVC??

[Wayne LaBanca]

I think my .02 is too late as you seem to be going another route but for future reference; Make sure you wrap the Teflon tape counter clockwise on the threads (Or in the case of a left handed thread, clockwise). If you go the other way, as you screw the pieces together, the tape is pushed back and does nothing. I have used pipe dope but only for low pressure systems like gas lines, I'm not sure it works in high pressure systems but that's from lack of use.

Thanks Wayne, I did have the tape wrapped in the proper direction but it still leaked.....

I tried the dope but it's been raining here so I can't test it. Seems to be OK though

Well, everytime I have a leak in a plumbing connection it's attributable to "User Error". Guess who the user is....

I think I'll try this.

seems safe. Hopefully it works well.

Hope by now you sealed the leak. Please repost what you used and where you got it. The link doesn't open.
Thanks,

I use telphon tape and then smear telphon paste ontop of the tape. Then I assemble the joint.

In our renovation of our church pool we replaced almost all plumbing except what is inside the gunite. We've still got a few drips to fix. A friend with 40 years pool experience told me to crush a piece of PVC with a hammer into very small pieces and let the pieces soak in an ounce or two of pipe cleaner. Make sure the cleaner is primarily methyl ethyl keotone (all PVC goops seem to have this in them). The MEK will dissolve the pieces into what is basically liquid PVC. Then take something like a popiscle stick and apply the stuff to your leaky area. I haven't had time to use this method yet but he hasn't steered me wrong yet. I'll report back after the repair.

Now THAT is a cool idea! But if you use it around a threaded fitting, it will be permanent...

Yeah, but suppose you can't or don't want to reopen the joint?

Yes, it will be permanent but I don't see that as a problem. PVC rarely just breaks so I think long-term fixes are good and, in our case, replacement of a multi-port valve would be required$$.

It is best to never use teflon tape on any threaded connection over about 1". For connections over 1" use the teflon pipe dope, it does a much better job.
