Ball valve required (versus a gate valve) for hot water heater installation

It is not that it is not up to code, it is just that after a while, the rubber gaskets dry out from the water, and will not seal, or even worst, will not move. Ball valves can do the same thing if left to sit for a long period of time, without rotating the valve.

At least every six months, when you change the clocks, go through the house and rotate the valves closed & open to make sure they still work. Replace any that allow water still through, or even gas, if used for gas shutoffs.

Maybe something bad, maybe something good. I guess we'll never know, 'cause you're going to guard it. You won't touch it, will you?
