Shut off valve replacement?
How hard is it to repair a copper pipe soldered on shut off valve? Is it worth trying to repair? If I unsolder the shut off valve, should I try and resolder on a new valve or uses a compression valve? If you need to repalce a compression shut off vave, can you just unscrew the old one and replace, or do you have to cut the pipe again? I do not have enough extra pipe to cut. Thanks
