In a water tank, how do you prevent a vacuum causing problems when water is added or drained? I assume that some sort of air is allowed to move in and out but you obviously can't just leave the lid open. Is some sort of anti-vacuum valve used?
Thanks a lot for your input.
In my application, the valve would go on the water tank (4).
