I'm replacing the faucets and associated isolation valves in my
bathroom vanity and have a general question. The valves are threaded
connections with brass ferrels and nuts. I cant figure out how to get
the existing ferrels and nuts off the copper pipe without cutting the
ferrel and I'm afraid of marring the pipe. Is there a risk of these
ferrels leaking if I hook them up to the new valves? They dont
currently leak but the valves are getting old and corroded.

thanks, dave


Leave the old ferrules on. The tubing has been distorted
(crushed) under the ferrule.

Apply a little sealant to the ferrule and connect to
the new stop valve. Don't try to overtighten; just
real snug should do it.
