Abstract
The valve assembly employs a remotely located button to open normally closed solenoid valves in the cold water line and hot water line via an electronic control module. In response to a second signal from the button, the control module causes the solenoid valves to close. A metering valve senses the flow rate of cold water and issues a signal in response to the flow rate being below a minimum flow rate to the control module to close the solenoid valves to block further delivery of water.
