I have a plumbing issue

[voyager 663rd]

The diverter on my Kohler tub spout has given up the ghost. The spout is a thread-on spout (as best as I can determine) and will NOT unscrew.

I've heated it and put a pipe wrench on--won't turn.
I've heated and hit it (gently) with a hammer and with the p/wrench--won't turn.
I've heated it then immediately ran cold water (pipe cold/exterior hot)--won't turn.

The thread end is totally corroded despite using a water softener so my question is:

as I can't spread the plastic tab (for fear of breaking it) off the old spout to remove the gate AND also cannot spread the plastic tab (same reason) on the new gate I want to:

cut the (existing) rod that moves the gate up and down so the whole gate/rod assembly can just drop down.

I would then get a universal (I hope) diverter repair kit and just sub that in to the existing non-removable spout.

Will that work?

Will that work? No set screw at 'wall' end. Really difficult to get an unblurry pic as the tub is 'in the way'

Can we get a pic of the spout?
Sounds like you need a strap wrench.

Yes, a picture will definitely help. Assuming you have the water turned off, try to open the valve and then un-thread it from the valve housing. I've seen that alot. A closed valve while trying to loosen it, is darn near impossible

Is that copper pipe coming out of the wall?

Ahh, not the diverter I was thinking

With my previous home owner fixes similar to this I would cut the 1/2 inch copper pipe as close as I could behind the spout and go from there. If you have to go into the wall it sucks but if you can solder a union and go from there.

That is way better in the long run than ending up with a leak behind the wall that you might not notice until it is too late.

We had a copper pipe in a bathroom that had a pinhole leak years ago. I noticed at the time that the carpet in the bedroom next to it was wet. After cutting a huge chunk of drywall in the bedroom out I found the pinhole leak inside the wall.

The fix was pretty easy. Cut out the bad pipe area and patch in a new piece. Then fix the drywall once I was satisfied the fix worked.

I'm sure there is a set screw in there still, the spout and the access hole are misaligned.
Can you spin the spout at all? If you can, try spinning the metal portion while looking at the white Teflon portion for a set screw, which will be an Allen screw.
Inside that white Teflon ring there are two black O rings which seal the spout to the nipple coming out of the wall, I'm sure they are harder than a rock by now, so if you can't find a set screw, more heat, or a grinding wheel on a Dermal, and tin snips to cut the spout away, then the Teflon sealing ring. The nipple coming out of the wall should either be threaded brass, but most likely copper pipe, if it is copper pipe be careful not to mar it while cutting it off. Go slow with a Dremel and cut of wheel, or mini hacksaw blade, cut the Teflon ring about 3/4s of the way through, then take a cold chisel or a big flat blade screwdriver and pop it a few times with a hammer to break it free.

Have you tried grabbing the metal part of the spout with Channel locks, while it's hot?
Then spinning it to look for the set screw on the Teflon ring? That's what I would do before attempting to cut the steel spout off. I'm pretty confident that the set screw just spun out of sight.

Let me know what you find, if you can't get it I'll give you my number, and try talking you though it.

The set screw will be in the window closest to the tile.
Some spouts have a threaded male adapter soldered on the end of the copper stub out.
So if that's the case, there might not be a Teflon sealing ring with a set screw.
If that's the case, more heat on the end of the spout, where the water comes out, may be necessary, to loosen up the gunk, or melt the pipe dope.
I'd wrap a wet rag closest to the tile to protect against heat transfer.
