Pipe Joint Compound or Silicon tape?

[mccurdyp]

I have some PVC pipe joint compound (Plasto-Joint Stick), and silicon tape. I'm leaning towards the pipe joint compound.
Any thoughts by anyone as to which might cause fewer issues, or would both be just as good?

Might help to know exactly what two sections of pipe (or fittings) you are connecting. Can you clarify of post a pic? Some products work best in certain applications.

Not sure which is better, but I will let you know my experience. I used joint compound that you buy in a jar with a brush and I had leaks around by return jet plumbing. I had to cut them out and use tape. I saw no issues on the suction side around the skimmer.

It's to connect the top of Pentair sand filter return/waste (black PVC?) to fittings

Something simple like that (open-ended waste line), just about either should work. Paste, teflon tape, etc. If you find later you need to seal a different line, let us know. Take care.

You would be better off using the unions that screw onto the outer threads.

If you want to use the MTA (male threaded adapter), I would suggest teflon tape followed by a paste sealant that sets up semipermanent.

Do not overtighten as the female part can crack, especially if you have too much teflon tape.

Use both. Tape goes on one way, so that it tightens itself when fitting is tightened. Then a light skim of pipe dope then install

I like the regular Teflon tape with silicone lube

100% for sure, on ALL threaded pipe connections, metal and plastic.

All thread sealed pipe connections, if there a oring then you want to use a silicone lube as a anti seize
