Find the isolation valve and shut it off
The isolation valve could be located in the basement, crawl space, or utility room.
Detach hoses from lawn faucet
Drain your hoses completely before storing them in a heated garage or basement.
Open lawn faucet and drain
Now the inside isolation valve is off and the hose is detached – open the lawn faucet and let drain. Leave open until spring.
Open the drain cap on the isolation valve
Open the drain cap on the valve body, allowing air to enter the pipe.
Check for leakes
Water dripping, no matter how slowly, can freeze the pipe. If your faucet is still dripping, your isolation valve may need to be replaced.
