I have an awkward plumbing problem. I am inserting a T-fitting into the flexible riser of my kitchen sink and in the process seem to have stripped the copper shank coming from the faucet. The fitting:
The 1/2" nut that attaches to the shank coming from the faucet turns, but does not tighten, nor does it come off. When the water is turned on, the joint leaks. So, I think I have stripped this thread somehow.
What's my next move?
If I cut the shank, then the stripped part is still going to be stuck in the adapter fitting. Also, the shank will get shorter, and I am not confident in my ability to thread a copper tube so that it is water tight.
As you can see from the photo, it is a 1/2" to 7/8" adapter which attaches to the copper shank coming from the faucet (the corroded pipe at the top). Even though the pipe has some corrosion on it, the joint itself does not.
I have tried very forcefully to pull/twist it off, but it just turns. Does not come off.
