Which pipe dope?

Rsmith99 · Apr 18, 2008

I have noticed plumbers all seem to have their preferred pipe dope.

I am plumbing my bathroom and need to attach the chrome shower extension to the copper stub. I also would like to use something on the metal tub drain threads where it screws into the PVC drain.

I want to make sure neither one leaks! Which pipe dope would you recommend?

Thanks!

For your shower arm, I would use teflon tape then pipe dope. Never fails me. On the drain you can just use pipe dope if you really want to.

I use any brand. Normally ones I pinch off licensed plumbers when they pay a visit for difficult work. You can get so much off plumbers. I've nabbed sandpaper, copper fittings, pipe, dope, tape, flues. They never say no. Could be the $500 call out fee I give them.

Next I might try to nick their torch. After that, their van!

Megaloc!

I usually wrap with teflon tape then apply megaloc over the tape.
Works for me!

Mega lock is nasty....

Mega lock, Recto seal, and Slick Tight are all in a class

by themselves.... all three on them seem to be about like slopping paint around...

whatever gets on.... the tools, the floor or carpet or whareever,
it seems almost impossible to clean up.....

I am 100% sure that they all work great,

but I prefer just the plain old Teflon tape and then cheap Oatey....

which is much more freindly to my clothes,

and anything else I happen to slop it on...

I dislike tape, so I use Oatey alone when I need to seal threads. When I was a kid on the farm, all we knew about was the bottom sediment of an oil based paint can. I guess it worked. Of course it undoubtedly had lead in it. Now we have so many choices we can color code our work. All of that while using 98% less threaded joints. How times change!

Coat both sides with pipe dope. Tighten the fitting. then take it apart. You will see that virtually ZERO pipe dope is on the threads. That is why I use teflon tape.

Seems to me that "virtually zero" is the amount I would expect on correctly-cut threads.

This is the best...it is all I use. I can't remember the last time I had a leak. It works on plastic fittings also.

The only thing I use teflon tape on is water heater nipples...the ones from china, which seem to be all of them, don't have the threads cut right...they go and go and go then bottom out.
