i'm a genius. years ago i replaced all the screw type emergency shutoff valves with ¼ turn ball valve shutoffs. it made it very easy to diagnose which faucet was dripping and needed it's cartridge replaced. planning on being near a home depot tomorrow so replacing the cartridge shouldn't be difficult
I think it’s a worthwhile change, especially if one has unreliable appliances. They take up a little more space though, so there has to be room for a lever even if it’s not always fitted. I have one on my toilet cistern. My plumber didn’t like me for fitting it though.
