Rialta is capable of delivering fresh water from two different sources, the on-board
fresh water tank or via the external city water connection. Water from the on-board
tank is delivered to the appropriate faucet or fixture via a 12V DC on-demand
pump. When connected to the city water supply, the pumps are not needed because
of the water pressure induced from the city supply system.
Sooner or later, every Rialta owner has one or more problems
associated with the water system. It could be the hot water heater, the water
pumps, or the filters associated with the water pumps.
