Plumbing Question

[jimroth]

Is it OK to glue threaded (NPT) connections? I got some threaded unions when I wanted slip, and it seems like it would be more secure and leakproof if it was glued.

I would think you'd be asking for trouble doing that... If you don't have glue in all of the threads you're going to get a leak somewhere and then you won't be able to tighten it. Also, there's probably only so much you can tighten it before the glue would set. You'll be ok with the threaded unions. You may even find you like them better than the slip!

I apply plumbers tape, it seals them well

gluing won't hurt anything though.

 

[Brian]

Yeah, I agree I would just use the Teflon Tape.

 

[jimroth]

Thats funny, because I was told to use that glop...teflon paste pipe dope. I think I'll try it your way.

 

[Brian]

FWIW I use the teflon tape on my skimmer pump and return pump. I haven't had any leak issues with it. Just be sure to wrap the tape in such a way that when you thread it, it doesn't start to unravel.

Good Luck!

Cover the thread 2-3 times, make it tight, wraping it in the directon you would screw it in.

That glue dryes fast and I would be afraid of not getting it threaded all the way before the glue will dry on you! I used teflon on all my threaded fittings and it worked great EXCEPT when you overtighten it! (They will crack!) :0

I use Teflon tape on everything that has threads.

It's great stuff and you can always unscrew the fitting and re-tape it again if needed.

The Teflon glop you are speaking of is the best. It is not a glue, just Teflon tape in a liquid form. It fills the gaps better and the threads screw on easier.

 

[Carlo]

Haven't tried the "glop" before. (always learning something).

Is that usually available at HD or Lowes?

Carlo

 

[mikem]

Yes Carlo it is. It's right next to the pipe dope. Don't get them mixed up. It says liquid Teflon tape.

 

[Brian]

Does that "glop" (I like that word!) come off the threads easily? Is it permanent?

 

[mikem]

Yes it comes off the treads with a rag. If you mean does it harden, then no. If I remember, I'll bring a thing of it to the meeting.

 

[Carlo]

Yes Carlo it is. It's right next to the pipe dope. Don't get them mixed up. It says liquid Teflon tape.

Talk about being "tunnel visioned". I'm in the pipe isles way more then I want to be and have never seen it. When I make a run there today it will probably reach out and slap me silly.

It's kind of messy and it never dries. I'm wearing gloves next time I ahve to use it. I bought it because the Sequence Dart pump instructions specifically say to use it rather than teflon tape.
