ABSTRACT:
The specification discloses a domestic water system reclaiming waste water in which a tap water line supplies fresh water only to a kitchen sink and as a replenisher for a reclaim system supplying all the water to a toilet, a lavatory, a bath tub, a clothes washer, laundry tubs and a dishwasher. Drains from the toilet and the kitchen sink lead directly to a sewer, and drains from all the other installations lead to a clarifier tank having an overflow to the sewer. A pump pumps water from the clarifier tank through filter tanks to all the installations except the kitchen sink and to a hot water heater supplying the lavatory, the bath tub, the clothes washer, the laundry tubs and the dishwater. An inline instant hot water heater is positioned in the tap water line to a hot water tap of the kitchen sink.
