Outdoor faucet freeze protector operates like a thermostat. Made of brass, stainless steel and cold impact-resistant polypropylene. Senses the internal water temperature arriving to the faucet, not the air temperature. Activates when the water temperature hits 37°F. No water can drip until the activation temperature is attained. As the water temperature fluctuates, so does the drip.
Installation: Thread to an outdoor faucet by hand. Turn faucet on all the way to ensure water pressure is available. If there is seepage, hand tighten until it stops.
Tip: Prior to cold season, it is a good idea to place the Freeze Miser in a freezer for several hours. Then quickly place on an outdoor faucet and open faucet; water should discharge through and flow should stop in a short period of time.
