I am calling that round compression ring thing that goes
over your toilet's inlet water pipe (1/2" copper?) a nipple.
If I am wrong, please correct me.
Question, how do I get the nipple off when I go to change
the water valve? The old nut is all stripped out and drips
and can't be tightened any more without ripping something.
There is tool for everything, there must be a tool for this?
Or, should I breakdown and just call a plumber?
I'm a little unclear here. You have a copper pipe between the shutoff
valve and toilet? Another question: are you in the U.S.?
I'd say the best solution would be to discard the metal pipe and get an
ordinary flex connector between valve and toilet. Much less likely to
leak in the future. It should screw onto both valve and inlet to the
toilet's flush valve.
Unless I'm missing something here ...
It's called a ferrule and you need a ferrule puller.
Or very gently squeeze it with long nose pliers to make round again &
slide it off.
Or very, very carefully cut it with a hacksaw (or a Dremel) at a 45
deg angle (don't score the tube) and break it off.
When you install the new valve (use a 1/4 turn valve) use some pipe
dope (I know, they;re supposed to me metal on metal but teflon paste
Don't over tighten.
