Freeze Miser Outdoor Faucet Freeze Protection

The Freeze Miser™ operates like the thermostat in you home.
It senses the internal water temperature arriving to the faucet not the air temperature. It can be 40°F or -40°F, it does not care. The Freeze Miser™ activates when the water temperature hits 37°F.
No water is allowed to drip until the activation temperature is attained.
No batteries or electricity required.
