“I needed to replace some bathroom sink valves, and when I went to turn off the under-sink shutoff valves I found the shutoff valves to leak badly from their shaft packing. I decided to replace the shutoff valves and ordered these right-angle 1/4 turn stopcocks. I found these to be well constructed and of good quality. Installed without any difficulty and when the system was re-pressurized, they worked like a champ, no leaks, and good flow rate when opened.”
