Toilet water supply valve compression ring corroded - how to unscrew the nut now?


Heya - I'm trying to replace my toilet water supply valve which is connected to a copper pipe via a compression ring and nut. But its stuck - I can't unscrew it and there is some blue/green copper corrosion in the threads of the valve that lead into the nut (the nut rotates on the copper pipe but I can't unscrew the valve from the nut). I think the corroded copper is making the threads stick and impossible to turn the nut to remove the valve.

I've tried WD40 and no luck. Now I've sprayed a solution of vinegar and salt onto the threads to try and eliminate the copper corrosion but it doesn't seem to be doing anything - I'm not sure it will seep deep enough into all the threads to have an effect anyways (will leave it overnight and see).

I'm afraid to try and hack-saw the nut as I'm not very adept with a saw and it will probably take until doomsday to cut the nut. Is it okay to just cut the copper pipe at the edge of the nut? I think it will be easier for me to cut copper. There is a good 1.5 inches of copper pipe sticking out of the wall up to the edge of the nut. The new water supply valve comes with a new nut which has a copper ring inside. If I cut the copper pipe do I just slide the new nut over top of the pipe then screw the new water supply valve into it?

I've attached a photo. If anyone can give me advice on the best way to get this old valve removed I'd appreciate it (I'm trying to connect a Bidet attachment which requires a different kind of valve).

THANKS!!

I've never had one not come off and I've removed hundreds.
Are you using one wrench to hold the valve and turning the nut clock wise as your facing it?

Joe asked, and I will---are you using two wrenches? one on the valve and one on the nut?

Like Joe--I've removed hundreds of those and never had one fight me----are you turning the correct direction?

Those valve are super cheap and flimsy too much force on the nut accually ovals the nut and it will never come off you have the room cut the copper and go back with a new good quality quarter turn stop. make sure the mating copper is clean and smooth, be done with it..

Yes, I'm using two wrenches, one on the valve and one on the nut, and I'm turning them the right way: just like in this youtube video:

The blue/green corrosion has not come off the threads despite leaving salt & vinegar solution on it all night. Its possible someone stronger could do it but I'm not a total wimp. I think I'm going to go ahead and cut the copper pipe and install a new nut unless someone else comes up with another suggestion.

Thanks for your help!

That does not appear to be a compression nut to me, that appears to be part of a 1/2 female threaded supply valve. Put a hold back pipe wrench on the stub out facing down to the right, and turn the nut (Valve) CCW with a pipe wrench, after you drain the tank, and take off the supply tube.

You've certainly lost me on the above statements. How the nut can rotate on the pipe but not rotate on the valve threads is beyond my comprehension.

I wonder if that is one of those cheap builder's grade push on stops disguised as a compression stop

shut the main water Off turn sink valve to drain water out of bathroom pipes. Now just take a copper pipe cutter and cut the pipe. You have plenty of room. Go buy one.

While your there grab a sharkbite fitting. Something like this.

I think your rite if it is. Put a adjust wrench on the copper pipe. Now pull foward toward the fitting. It might pop it loose. They actually make a tool for this I think a adjust wrench mike work instead.

I've just tried pulling the valve/nut part off the copper pipe with wrenches but its not budging. I don't really want to buy any more tools so I'm going to cut the pipe and start fresh!
