Is there a trick to sealing threaded PVC??

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.

Yeah, but suppose you can't or don't want to reopen 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...

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.
