Vetus anti siphon valve check - prevent flooding the engine with seawater

If you experience water drips from your siphon valve vent hose the valve inside can be stuck or filled with dirt. The valve is one of the overlooked things in many boats but must be checked regularly. The system is in many boats mostly a unit made of steel but in my boat it is a 100 US Dollar plastic valve made by Vetus who also make a lot of good quality equipment for boats.
