1. A valve assembly comprising a housing having a cold water inlet, a hot water inlet, a cold water outlet in communication with said cold water inlet and a hot water outlet in communication with said hot water inlet;
a first normally closed solenoid valve in communication with said cold water outlet for closing off the flow of water therefrom; a second normally closed solenoid valve in communication with said hot water outlet for closing off the flow of water therefrom; a flow metering valve in communication with said cold water outlet for sensing a flow of cold water from said cold water outlet and delivering a signal in response to sensing of a flow rate below a minimum flow rate; an electronic control module electrically connected to said first normally closed solenoid valve, said second normally closed solenoid valve and said metering valve; and a button electrically connected to said electronic control module, said button having an OFF position and an ON position and being manually movable from said OFF position to said ON position, said first normally closed solenoid valve being responsive to said button being moved from said OFF position to said ON position to allow a flow of water from said cold water outlet for a predetermined time period, said second normally closed solenoid valve being responsive to said button being moved from said OFF position to said ON position for said predetermined time period to allow a flow of water from said hot water outlet, and said electronic control module being responsive to said signal from said metering valve to deliver signals to each said solenoid valve to close and thereby block the flow of hot water and cold water. |
