When our plummer came last time to do some work for us, he told us a story where one of his clients tried turning off the water with a particularly sticky knob and broke it right off. They had to turn off water to the whole house. So, this plummer said that we should turn the water valves turn-off knobs every 6 months to keep them supple. I have a reminder and I've been doing it ever since.
