I'm updating some of the piping below my kitchen sink and trying to understand options to repair a water stop valve that was broken when we moved in. The stop valve's wheel was separated and laying on top of the pipe underneath it. The wheel doesn't seem re-attachable because of how close the two pipes are.
Is there an obvious way to remediate this? As it stands, the only way I can shut off cold water to this faucet is by fully shutting off the water for my residence. It would be nice to have the option to shut it off from this valve.
