Protect your potable water supply with this 12" frost proof wall faucet. It keeps water free of contamination from back siphonage or backflow pressure. You can rely on the chrome construction for lasting durability. To prevent winter water-line freeze-ups, install this frost-free faucet with a slight downward pitch. The downward pitch ensures any water left in the faucet drains out through the water spigot. When left attached, water may become trapped and cause the faucet to freeze and burst.
