Help, I have this 2" pipe plug into a 90 elbow that I can't seem to stop dripping. It dripped 1/4 cup in a day.
I've recently removed an old coal boiler. There were four 2" pipes that I cut off, those all sealed fine. All but one of the pipe stubs came out without too much effort. One was very difficult though. It took lots of heat and 5 feet of pipe on my 2 foot pipe wrench to get it apart. The pipe itself twisted under the strain but it finally came out. The threads in the elbow look good. I cleaned both sides of the threads with a wire wheel and sprayed with brake cleaner to de-grease them.
First time I used a pipe joint compound called Leak Lock from Highside Chemicals Inc. but drip, drip, drip.
Next I tried 4 turns of white teflon tape but drip, drip, drip.
Then I found a roll of a thicker pink teflon tape, four turns...drip, drip, drip.
Lastly I tried 4 wraps of white teflon tape topped with a coating of the Leak Lock...drip, drip, drip. (I let it sit a few days before filling the system)
My only guess is that the elbow went oval when the pipe stub twisted.
Does anyone have a sure fire tip to keep the fitting from dripping? I'm not really concerned about ever taking it apart. It won't ever see more than 30 PSI of water pressure.
