Shut off outdoor faucets
Turn off outdoor faucets at their shutoff valves. Open the faucet and then open the bleeder cap on the shutoff valve to drain any water out of the pipe. If you don’t drain the pipe, it can still freeze and crack. Leave the bleeder cap open with a bucket underneath to catch any drips. If the dripping continues, your shutoff valve needs to be replaced.
Install frost-free sill cocks
Unlike a typical faucet, the working parts of a frost-free sill cock— valve, seat and washer—are located up to 18 in. inside the wall instead of right at the faucet. When the sill cock is properly installed, with a slight downward pitch, water drains from the pipe every time you turn off the knob at the faucet. Frost-free sill cocks are available at home centers for $15 to $55.
