Abstract
The above-entitled system is especially useful in recreational vehicles but is obviously adaptable to other arrangements. As obviously applied to a recreational vehicle (RV) having a fresh water tank, a grey tank and a waste tank, the system includes a plurality of electrically activated valves, one for each tank, so arranged as to be individually operated exclusive of each other in a convenient sequence for filling the water tank, draining and rinsing the grey tank and finally draining and rinsing the waste tank. The grey and waste tanks are connected to a water supply line by separate lines, each of which includes spray nozzles assuring cleansing of the tanks. A pump is provided in conjunction with the water for use in the event of a situation in which an external water source--such as city water--is not available.
