Re: Plumbing ....... Grrrrrr
The trick with valves is not to open them fully, so when you need to close them you can turn them both ways to free them.
I always do that... open fully then turn them back a half. But gate valves have a thread to drive the gate across the flow... and the thread is exposed to the water flow. Hot water deposits scale in the thread and the blasted thing seizes. I usually try to remember to open and shut them every few months... but I guess I got lazy
