Reuse Compression Fitting?

hi all,

i just recently installed a quarter turn angle valve (compression fitting) for the dishwasher supply line. unfortunately it's way too low for the new base cabinet. i would have to cut out a huge chunk of the base cabinet back wall and floor. if i re-route i can minimize the amount of the cabinet floor i have to cut out.

my question is:

how do you guys feel about re-using the angle valve since it's brand new IF i use a new brass compression sleeve/ferrule on brand NEW copper pipe?

i've had one experience before where i tried to install an angle valve w/ a compression fitting where the old valve was (there wasn't a lot of copper pipe to work with) and it leaked albeit slowly. i assumed it was because the copper pipe where the compression took place was no longer the same or maybe it was damaged when the sleeve/ferrule was removed.

thanks for any input!

Perfectly acceptable to reuse any compression fitting with a new ferrule.

I bet that's right. I think you are supposed to cut the copper pipe back a little when you reuse the same pipe. At least I think that's the case.

The pipe can get deformed so yes good idea to install on virgin pipe!

thanks guys! i was able to reuse the angle valve with a new ferrule on virgin pipe. almost bought the 1/2 inch ferrule but then noticed it was OD (outside diameter?). the 5/8 ferrule worked great on 1/2" copper pipe. no leaks!
