How does a water system on a boat work?
Water pumps on a boat can be either electric or manual. An electric pump pressurizes the entire water system. The pump cycles on and off until the tap is closed. The inlet of an electric pump connects directly to the tank outlet (or multitank valve), and the outlet supplies water to all faucets and appliances.
