❄️ Freeze Miser® Outdoor Freeze Protection

Smart, Automatic Freeze Protection for Outdoor Faucets, Hydrants & Livestock Waterers

The Freeze Miser® line offers a simple, dependable, and water-saving solution for protecting outdoor plumbing from freezing temperatures. Designed for homeowners, farms, and livestock operations, Freeze Miser activates automatically when water temperature drops to 37°F (3°C), releasing only the minimal amount of water needed to prevent freezing — no electrical power, no insulation wraps, and no constant dripping.

If you’re looking for an easy, reliable way to keep faucets, barns, hydrants, RV hookups, or automatic waterers from freezing, Freeze Miser delivers all-season protection with near-zero maintenance.

How it works

  • The Freeze Miser operates like the thermostat in your home.
  • After installation, it senses the internal water temperature arriving to 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!
