Review on 🚰 Dual Compression Outlet Angle Stop Valve, Plumbing Fitting, Quarter Turn, Single Handle, with Multiple Select Positions, Water Valve Shut Off 1/2" NOM (5/8" OD) x (3/8" x 3/8") by Frank Ridl

This worked great, but one thing to keep in mind. It's not just an on/off valve, it actually has 3 positions to close one or both outlets. This might be a nice feature, but it's not so obvious which ones are enabled or disabled. No installation hassles - just twist until both work, but if you only need to turn one off it's not that easy to tell if one or both are off. Not easy but not impossible because it is marked from the front, although difficult to see and a bit difficult to interpret. If you have time to get a flashlight and find out, you can do this.
