I need some advice or recommendations for my fresh water system. The original air vent for the fresh water system had a hose that attached to a stanchion and vented through that onto the deck. When I was doing my refit I filled in the stanchion and moved the vent to inside the cabin. I attached a check valve to the end of the hose, but didn't think that it doesn't allow air out when I am filling the tanks so they become pressurized.
Does anyone know of a check valve that will prevent water from going out, but will allow air in and out both directions?
