  • Patent number: 10385761
    Abstract: An automated flushing system includes a base having a flow inlet, flow outlets and a flow manifold, the system also including solenoid valves and a pressure switch mounted upon the manifold. The flow manifold includes a main flow channel connected to the flow inlet, and auxiliary flow channels interconnecting the main flow channel with respective ones of the flow outlets so as to provide flow communication in parallel to the flow outlets from the main flow channel. Each solenoid valve extends into a respective auxiliary flow channel and is actuatable between an activated status and a deactivated status to allow and block flow communication of liquid through the respective auxiliary flow channels to a flow outlet. The pressure switch in flow communication with the flow inlet is configured to sense that the pressure of liquid entering the flow inlet is above a preset minimum before initiation of automated flushing system operation.
