And there's a very good chance that if you don't use it regularly, it will break when you actually do need to shut it off in an emergency. They're just junk, and need to be replaced.

I don't disagree that the plastic push-pull Accor valves are cheap. But, there are tens of millions of them being installed around the country and they do comply with the National plumbing code. They are even installed in multimillion dollar houses. I have had 12 of them in my house for 8 years, and have had no leaks or other issues. I only use them occasionally when I need to fix a toilet. If it isn't broken, I probably won't fix it. But, I don't fault someone who wants to replace them. But, any valve you install can fail.
