  • No water is released until the activation temperature is sensed.
  • The Freeze Miser is on guard 24/7!

Frequently Asked Questions about Freeze Miser

Does Freeze Miser® waste water?

No. It releases only the minimal amount of water required to prevent freezing. This is significantly more efficient than leaving faucets dripping overnight.

When does it activate?

Freeze Miser® activates at a water temperature of 37°F (3°C) — well before freezing occurs.

Why does Freeze Miser® drip when it's not freezing outside?

If water sitting inside the pipe is colder than the air temperature, the unit may activate temporarily. This is normal and ensures the line does not freeze.

Can I use Freeze Miser® with livestock waterers?

Yes! Freeze Miser® is commonly used on:

  • Outdoor hydrants
  • Automatic livestock waterers
  • Stock tanks
  • Barn faucets

Great for cattle, horses, sheep, goats, chickens, and more..

Does it require power?

No electricity is required. Freeze Miser® works using a temperature-responsive valve system.

Will it work with low water pressure?

Yes. Minimal pressure is required for Freeze Miser® to function properly. 10 PSI.

Can it be used on RVs?

Yes — it is very popular for RV winter protection.

How long does it last?

Freeze Miser® is built to last multiple seasons and withstand harsh winter conditions.

What is required to install the Freeze Miser

Installation of the Freeze Miser requires threading to a faucet, hose, or another device securely and opening the water supply valve to full open. Check to ensure that the Freeze Miser connection to the device is secure, and no seepage is around the threads. If placed on the end of a hose, the Freeze Miser should be off the ground enough not to sense any temperature feedback other than the hose water temperature.

What might the Freeze Miser run lots of water when first installed or reinstalled

If exposed to ambient air below 37°F/3°C before actual installation, the Freeze Miser may be in the open position. The Freeze Miser will immediately release water after the initial installation and continue discharging water for 2-5 until sensing the water temperature being released. After this self-adjustment, the Freeze Miser will release water below 37°F/3°C to protect the exposed piping and/or faucet from freezing.

The Freeze Miser will only protect the supply piping furnishing water directly to the Freeze Miser. A pipe that is an offshoot of the same pipe or hose offers no protection because there is no way to purge the water as it approaches freezing temperatures. Each faucet requires a Freeze Miser for freeze prevention.

We recommend yearly testing of the Freeze Miser before installation. Place the Freeze Miser in the freezer for an hour, remove and quickly install on an outdoor faucet. Turn the water supply valve to a fully open position. Water discharges thru the Freeze Miser at a maximum rate for 2-5 minutes. The Freeze Miser will automatically close the water release port until the water temperature falls below 37°F/3°C. The Freeze Miser will only resume the drip rate’s autoregulation if the water temperature drops below 37°F/3°C.

How much water will it drip?

Many factors contribute to the water release rate and include ground water temperature, amount of water in pipe or hose above ground it is protecting, air temperature, Sun, shade and wind (wind gets the water temperature to ambient air temp quicker). Drip rates will all very. Example: you can have identical faucets on your home one on the North side and one on the South side and air temp is 25°f. The one on the North side is releasing water a small steady rate where the one on the South side is dripping maybe a drop every 10 seconds.Note: as the WATER temperature fluctuates so will the release rate.

Can I hook it up to my water hose?

Yes, the Freeze Miser will protect up to 150 ft. of hose. Make sure the end of the hose with the Freeze Miser is off the ground. Hang it over a chair or fence as the Brass is what senses the water temp in the hose. Please visit the “Installation" page and go to Video “How to install on a Hose”.

How many feet of hose or pipe will the freeze miser protect?

The Freeze Miser will protect up to 150 ft. of hose or pipe above ground. If you need more, put a Y valve and a Freeze Miser every 150 ft of hose and keep the connection off the ground. Make sure the end of the hose has a Freeze Miser as well.

Will it work at -20 Degrees F?

The coldest temperature we know of is -35°F without the windchill on 150 ft. of hose in Northern Montana.

What is the lowest temperature the Freeze Miser will work in?

The Freeze Miser doesn’t sense your air temperature, it senses the water temperature. When the WATER TEMP FALLS BELOW 37°F it will activate. The coldest recorded that we know of is -45°F with windchill. -35°F without on 150 ft of hose.

Will it protect pipes or hoses that do not directly supply water to the Freeze Miser?

It will not. A hose or pipe branched off the main pipe protected by the Freeze Miser has no freeze protection because the water released by the Freeze Miser is not released from that portion of the piping. For freeze protection, that piping requires a Freeze Miser at the discharge end also.

Do I still need to drip my indoor faucets if I have the Freeze Miser on my outdoor faucets?

Yes, as the piping systems to your indoor faucet are off different supply lines and the Freeze Miser can’t support those supply lines. The Freeze Miser only protects what you have it on the end of.

How do I know if it is working or not?

Ambient air temperature of say 28°F may take a while to chill the water within the Freeze Miser to its activation temperature of just under 37°F/3°C.

It's below 37 degrees and my Freeze Miser is not working. Why?

The Freeze Miser, once installed, will ONLY ACTIVATE when the WATER TEMPERATURE FALLS BELOW 37°F.

Why does the faucet on the south side of my house drip less than the faucet on the house's north side?

Many reasons factor into the difference, including windchill, shade, length of piping exposed etc.

What factor does groundwater temperature have on the drip from the Freeze Miser?

The actual groundwater temperature, before being exposed to ambient air at the surface, can make a substantial difference in the water the Freeze Miser will release, all other factors being the same, i.e. Air temperature, wind, etc. With groundwater temperature of 55°F – 65°F the Freeze Miser will release less water than if groundwater is 45°F. It is possible that if the ambient air temperature is above 37°F/3°C, the Freeze Miser may still release water because the water it is sensing is less than 37°F/3°C.

Can you adjust the settings of the Freeze Miser to drip more?

No, there is not an adjustment mechanism on the Freeze Miser. To adjust will void the warranty.

What happens if its fails? How do I know if it fails?

If the Freeze Miser fails, it falls back to its “fail-safe” mode, which means it will continuously release water above 37°F/3°C. This would ensure that your faucet/hose is still protected in a freezing situation, and after it is evident that it not cold, you have notification that it needs replacing.

Can the Freeze Miser be facing upwards and still work?

The Freeze Miser should be horizontal or vertical, with the small brass end pointed downward in the upright position.

Will it work on a Y connection, where I have my water hose on one side and the Freeze Miser on the other?

Yes, and it will protect the faucet, but not protect the hose on the other outlet. Either take the hose off or put another Freeze Miser on the hose end and make sure both valves on the Y and the faucet are all opened.

Does my faucet need to be turned all the way on?

Yes, and the Freeze Miser requires at least 10 PSI water pressure. This ensures that when the Freeze Miser opens to allow 37°F/3°C water to be released, there is enough water pressure to release as required.

Will water quality affect the ability to function properly?

Based on potential water quality problems, i.e., rust, scale, sand, or other impurities, it may be necessary at regular intervals to check the Freeze Miser for this issue. After removing the Freeze Miser, look inside the threaded end for anything visible. Wipe with a cloth, blow out with air, and if satisfied, it is clean, reinstall. If the particulate matter is wedged between the stainless-steel rod and the seals, subject the Freeze Miser to ice water until the stainless-steel rod is recessed away from the seal. Immediately place on an outdoor faucet and open the valve allowing the pressured water to flush any additional particulate from the Freeze Miser.

Will the Freeze Miser work on a faucet with a vacuum breaker on it?

Yes, the FM will work unless the vacuum breaker is bad. When you turn the water on and it starts leaking at the connection, that means your Vacuum breaker the O-ring went bad. You can replace the O-ring in the vacuum breaker or get a new one. If your city doesn’t require one you can leave it off.

How do I store my Freeze Miser at the end of winter?

Take it off your application and let it dry for a day or so. Then put in zip lock and store at room temperature. You can also store it in your freezer, that way it will be in the open position when you take it out of the freezer next fall, and you can put it directly on your faucet and turn the water on. It will run for 3 to 5 minutes then shut off and now you are ready for winter

I have a Freeze Miser that continues to drip when it is above freezing?

Sometimes if there is debris in the water something could get stuck in a release port not allowing the rod to re-seal. Simply take the Freeze Miser and put in the freezer for an hour. Remove it and put it on faucet, then turn the water on and it will run water for 2 to 5 minutes then shut off. This will blow out anything caught in the port.

Can I install the Freeze Miser on a float valve?

Yes. Make sure the Freeze Miser will not come in contact with the water in the tank, as the brass is what senses the water in the hose coming to the Freeze Miser and the float. This may result in it freezing up.

Should I adjust the water pressure on my faucet?

It is IMPORTANT NOT TO ADJUST the water pressure down to try to control the release rate. By doing so you can potentially freeze up your water line and hydrant. (remember the more hose or pipe above ground you are protecting the more of a release rate you will have). Make sure you have a good rubber winter hose that will help insulate the water.

❄️ How Freeze Miser® Works

Freeze Miser® is engineered to protect outdoor water systems using a patented temperature-sensing valve.

Temperature-Sensing Activation

  • The Freeze Miser® continuously senses actual water temperature, not air temperature.
  • When water temperature reaches 37°F / 3°C, the valve releases a controlled drip.
  • This keeps water moving through the plumbing, preventing ice formation.

Water-Saving Technology

Unlike leaving a faucet running at full drip overnight, Freeze Miser® releases only the amount of water necessary to keep the system above freezing.

This reduces waste, avoids guesswork, and protects pipes automatically.

Hands-Off Protection

Once installed, Freeze Miser® works 24/7:

  • No electricity
  • No thermostats
  • No insulation covers
  • No need to constantly adjust water flow

Great for farmers, ranchers, homeowners, and anyone who needs worry-free freeze protection.

🔧 Installation Guide

Installing Freeze Miser® is quick and requires no tools for basic faucet setups. Below is a summary of Freeze Miser’s installation recommendations:

Outdoor Faucet Installation

  1. Hand-tighten Freeze Miser® onto the faucet/hydrant.
  2. Ensure the faucet is turned on fully so water can reach the valve. A minimum of 10 PSI water pressure is required.
  3. Leave Freeze Miser® installed throughout freezing conditions.
  4. Water will drip only when needed (at 37°F water temp).
  5. Remove in spring if desired.

Important:

If the valve seems to drip before freezing conditions, this is normal — it is sensing water temperature, not air temperature.

Stock Tank Installation (Livestock Waterers)

  1. Install the Stock Tank Freeze Miser® on the supply line or designated port.
  2. Make sure water flow is constant to allow the valve to adjust temperature.
  3. The unit will drip as needed to keep water flowing and prevent ice in lines.

RV / Utility Installation

  1. Attach Freeze Miser® to the freshwater hookup or outdoor faucet.
  2. Open faucet fully.
  3. Let the Freeze Miser® maintain freeze protection automatically.

Pro Tips

  • Install the Freeze Miser® in a horizontal or vertical position. In the upright position, the small brass end should be at the bottom. Do NOT install the Freeze Miser® with the brass end pointed upward.
  • If placing on a hose (150 feet or less) – Keep the Freeze Miser® off the ground to ensure the Freeze Miser® senses the water’s temperature only in the hose.
  • Expert Tip – Before the cold season starts, we recommend placing the Freeze Miser® in a freezer for several hours. Then quickly place on an outdoor faucet and open fully. Water should discharge through the Freeze Miser®, and the flow should stop in a short while.
