Threaded PVC Leaks!

[jason999]

I used 3 turns of teflon tape, hand tightened and then turned my threaded pvc fitting1-2 more turns on the back of my new jet fixtures. I have leaks!
I tried rectorseal and still have slight leaks!
I'm considering both teflon tape and sealer?
Also, would PVC primer and glue be better? The fitting is on the back of the pool wall. I can't imagine that it can be changed later without busting concrete and digging gravel.
Isn't this a very permanent fitting?
Do builders ever glue these threaded pvc fittings to be sure they won't leak?

Thanks

Teflon tape should not be used on threaded PVC. Read the attached PDF on The "Do's and Don'ts" of Assembling Threaded Plastic Fittings.

It sounds like the threads on the fitting and the fixture you are using do not match.

Give us the details of the specific products you are trying to mate together.

Try using Plasto-Joint Stik.

Thank you for the response.
Some manufacturers say yes to teflon tape. Others say no.
It certainly didn't work with what I did...

I believe it's a Hayward pool jet and I connected standard 1.5" threaded pvc.
I tried Rectorseal but the pipe seemed to thread deeper the second time and still leaked slightly.
I'm not sure if I compromised the female threads. ?? Would the sealant you show be better?
What are thoughts on using:
-teflon tape and sealant?
-Silicone
-PVC primer and glue

I have heard of many contractors using silicone on threads. Would it last?
Is there a problem with PVC glue on threads?

DO NOT glue the threaded joints.

Many contractors do many things that screw up things long term.

Post pictures of the jets you are trying to screw in.

It is possible that the fitting cracked if you threaded a male-threaded portion completely into it.
Plasto-Joint is, basically, Teflon tape in stick form, but you its hard to get a large-enough amount on a PVC fitting to work well.
Hayward pumps used to specifically say to not use a liquid joint sealant like RectorSeal so it may apply to their fittings as well.
I have always used 5 or 6 tight wraps (sometimes more if the joint was still loose) and then a light coating of silicone sealant over that, for the past 34 years, with good results and no problems.
Then, the pipe or adapter cannot be threaded entirely into the fitting or pump as pipe threads are tapered, expanding the further you thread them in. There should always be 3 - 5 threads visible on a properly threaded joint.

Trying to glue threads is not going to go well. The glue sets up before you can thread the parts fully together. I would drill/ream out the female threads to make a socket before trying to glue threads.

Pipe dope/sealant and/or tape usually work well. When it doesn't it usually because it's been over or under tightened or one of the parts are cracked.

If you have leaking, carefully look over the female fitting to make sure it's not split or cracked.
