While the usual winter faucet covers, fabric faucet socks, and the manual drip method can protect an outdoor faucet if temperatures don't drop too low, they often don't provide enough protection to prevent pipes and faucets from freezing. Blue Penguin's Freeze Miser prevents freezing, no matter how cold the temperatures or for how long - made of sturdy brass, stainless steel and cold impact resistant polypropylene.
