Keeney’s TimeOut shutoff valve is a cost-effective engineered solution that is manually activated and automatically shuts off the water supply to washing machine hoses. It helps protect a building from flooding associated with burst hoses. Simply push the lever to start the flow of water and the valve shuts down after a maximum time of 2.5 hours.
