Freeze Miser 2 Pack Outdoor Faucet Freeze Protection

The Freeze Miser operates like the thermostat in your home. After installation, it senses the internal water temperature arriving at the faucet, not the air temperature. The Freeze Miser activates when the water temperature drops below 37o F/3o C. No water is released until the activation temperature is sensed. The Freeze Miser is on guard 24/7!
