I have read some of the posts but despite following the directions, I
still find that my 1/2 inch compression fitting for a bathroom sink
supply pipe (copper) is still leaking very slowly from behind the nut.
I did the following:
+ Cleaned the copper pipe with emory cloth
+ The pipe itself is new, so hopefully the roundness is not an issue
(no visual flaw detected)
+ I inserted the nut, then the ferrule (out about 1/8th of an inch)
and then tightened (not too much).
+ I donotice that I can physically slide the nut back and forth on the
pipe (does it mean that I probably need to tighten it some more?)
What can I do to prevent this from leaking? The choices I have at this
point are to call a professional plumber and have him solder the
Would it help if I put teflon tape around the pipe and then inserted
the nut and the ferrule on top of the pipe (thereby ensuring a snugger
fit between the ferrule and the pipe)? I havent tried this approach
though several folks have indicated that it works.
Thanks for any advice that you can provide,
