Great productI had to replace the shut off valve in our kitchen sink when I replaced out faucet. We have well water and is very hard. I am assuming that with the hard water and rust, the valve finally gave in. When replacing the faucet, I was able to shut the valves, but when turning them back on, it started to leak. No amount of tightening helped. So I decided it was time for these valves to be replaced. I replaced both hot and cold valves, even though only the hot was leaking. It went in well - I had to use the existing nut on the old valve and it fit nicely. No leaks and it looks nice. And it's only a quarter turn valve, not like the old valve where it was like a screw valve, requiring several turns. I guess because of our water, it would be a good maintenance to turn these valves on and off at least once a year.
