I am remodeling my bathroom. I quickly realized that I do not have any means to shut off the water to the faucet (other than the main line to the house) unless I install a shut-off valve under the sink. In the process of doing this, I carefully removed the old 90 degree bend, cleaned the extruding pipe with emery cloth, and cut the pipe back behind where the old compression ferrule was. I then installed the new compression type 1/4 turn shut off valve.
It leaked from the compression ring side. So I tightened the compression ring. It still leaked. So I tightened a little more... until I overtightened it and it leaked from both sides.
I removed the whole assembly, reinstalled with a new ferrule, hand tightened, then tightened 1/2 turn with the wrenches. It leaked from the valve side. I tightened another 1/4 turn with wrenches. More leaking from the valve side. Another 1/4 turn of the compression ring. More leaking from the valve side.
I removed the whole assembly. Cleaned up the copper tubing with emery cloth again. Cut the tubing back once more. Installed a whole new compression valve with new ferrule, and this time I even used Teflon tape on the threads of the valve.
It still leaked, albeit only a little. So I gave it one more 1/4 turn with the wrenches. It still leaks.
What am I doing wrong here, and how do I most easily fix my problem? Do I need to replace the copper tubing from the wall with a new piece to ensure the integrity of the tubing? Should I just attempt to sweat/solder on a shut-off valve? Is there a way to salvage the compression fitting since its so much easier to remove and install?
