plastic valves are meant to be opened ONCE, to drain tank at end of

Where did you get that?

I've been draining my tank every year and never had a plastic valve leak

might depend on how hard the water is, it stops the valve from opening
and closing around here plastic ones often break when disturbed. the
handles twist off
