A nipple is a length of pipe (any where from 1 inch to however many
feet).

The ring that goes with a compression fitting is a ferrule. The old
ferrule cannot be reused. The new valve will come with one. They are
also sold separately (batteries not included, ha ha).

Please go talk to the plumbing people at your small town hardware
store. They will probably suggest you change the angle valve, lead in
tube, and also the fill valve for the toilet. Probably less than $40
in parts, and well worth it.

Hi All,

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?

Many thanks,
