Abstract
A whole home water appliance system includes controller circuitry, a primary sump pump driven by an electric motor, and a secondary sump pump driven with a flow of water. The system also includes a water control actuator operable as a water main control device for a domestic water distribution network and a flow meter to measure the flow of municipal water supplied to the network. The controller circuitry selectively energizes the primary sump pump to extract liquid from a sump pit based on a liquid level in the sump pit. The secondary sump pump independently controlled by a hydraulic level sensor to extract liquid from the sump pit. The water control actuator controlled by the controller circuitry to shut off a municipal water supply to the domestic water distribution network in response to detection of a leak. Communication circuitry included in the whole home water appliance may wirelessly communicate.
