I'm replacing the shutoff valves in an old, broken kitchen sink. When I cut off the old ones, there was such a tiny stub left, I feel as if I need to extend it forward so I can use them easier. Is it okay to lengthen that stub about 6"? It's a 1/2" copper line.
I'm installing a new sink and faucet too, the supply lines are no problem. This is more for comfort and convenience in the future.
