Freeze Miser Outdoor Faucet & Spigot Freeze Protection – Patented Valve Shield, Activates at Water Temperature Below 37°F/3°C – Durable Winter Cover Alternative – Quick Install, Saves Water – 1 Pack

Now the same patented technology used to protect industrial waterers from freezing is available for ordinary outdoor faucets. Installed with faucet turned on (see Installation) the Freeze Miser senses the internal water temperature. It's activation temperature is 37°F/3°C Until the activation temperature is attained, no water will be allowed to drip. After the water temperature has dropped slightly below 37°F/3­°C, the Freeze Miser will release water until the internal water temperature is again above 37°F/3°C and then stop the water release. Water utilities, water wells etc. almost always supply water to the end user that is above 37°F/3°C. The Freeze Miser should not be wrapped with insulation or it will not be able to sense the cold quickly. One area of significant time and water waste is a result of having to drip faucets manually to prevent them from freezing. Typically, the faucet has to be dripping water at a rate that will prevent the faucet from freezing at the coldest temperature anticipated. This method wastes a lot of water. The Freeze Miser outdoor faucet freeze protector provides a better method of freeze protection using the least amount of water possible.
