so is it really necessary for manual valves? Coldest it gets here in Missouri is 0 degrees fahrenheit, but that would be pushing it. I have water traps between my tank and my manual valves so would there really be a problem?

This is my setup...
Water traps before the tank because its a steel tank. Wanted to keep as much water out as possible. Should I just add it to the tank and call it a day? I live in MD/PA so it gets pretty cold here. Nothing below like 25 I would say, but still below freezing.
