It is best to turn on your system during the warmest time of the day when anticipating freezing conditions. Be sure the outside temperature is 40 degrees fahrenheit or above when you run your system. You ABSOLUTELY do not want to run your sprinkler system during a hard freeze as this will cause damage to your system.
You should shut off your irrigation system just before temperatures in your region begin to dip below freezing at night.
Running the sprinkler system when it is 32 degrees Fahrenheit or below is cause for concern.
While you may be eager to get your lawn back to its pristine green state, it is important to remember that temperatures at and below 32 degrees Fahrenheit put your sprinkler system at risk of freezing.
Normally, this is not a problem because the main shut-off, zone valves and heads are below ground and stay relatively insulated. However, if the temperatures do dip down into the 20's, or temperatures remain below 32 degrees for an extended period of time, your irrigation system can be damaged.
The scientific team found that dust-free water on a smooth, clean surface will drop well below 32 Fahrenheit (zero Celsius) before it freezes. In this state, the water is called "supercooled." But once one crystal does form, the supercooled water will freeze rock-solid in an instant.
Heat from a fire will cause the liquid to expand, once the pressure gets too high the bulb will burst and the water in the system will be released. The liquid in the sprinkler head comes in a variety of colors, which indicates the temperature required to activate the head: Orange – 135° F. Red – 155° F.
Pipes are at risk of freezing when temperatures drop below 32 degrees Fahrenheit, but they most commonly freeze at temperatures of 20 degrees and below. (Keep in mind, wind chill increases the risk of freezing.)

A sprinkler system will freeze if the temperature falls below 32° F (0° Celsius). Now, most indoor sprinkler systems are inside of buildings or homes where the temperature won't ever drop into the danger zone.
And those temperature swings and freezes can cause havoc with your outdoor irrigation system. Whether you face frozen pipes or some other form of winter pipe damage, you could end up with a flooded lawn and pricey landscaping problems and home exterior issues in the blink of an eye.
Nothing should be in that area between the bottom of the sprinkler heads and the imaginary horizontal plane parallel to the ceiling that is 18 inches below. This is done to allow an even and unobstructed spray pattern from the sprinklers when triggered to extinguish the fire.
If you have not blown out your sprinkler system, you will be fine. It takes a sustained hard freeze of around 28 degrees to potentially cause sprinkler damage.
You'll want to winterize your sprinkler system at least one week before the first “hard freeze,” a term that refers to when the outdoor air dips below zero degrees Fahrenheit. Keep an eye on local weather reports so that you can get a good sense of when the first hard freeze will take place.
This is an option if your irrigation system is equipped with a manual drain valve. Simply turn off the water supply and open the manual valves at the ends and low points of the piping. Also, make sure to drain the backflow device.
Anywhere from 55-62 degrees will keep your pipes from freezing while cutting your heating bill dramatically. PROCESS: While the weather outside is frightful and inside is so delightful, sooner or later you'll have to brave the blizzard and leave the house.
Pipes can freeze in as little as six to eight hours, meaning they can freeze overnight. If the outside temperature is below 32 degrees F and your pipes are unprotected, your chances for a frozen pipe increase.
Any of those circumstances could lead to pipes freezing – especially when the outside temperature is 20 degrees or colder. Generally, keeping your home at 55 degrees or warmer will prevent pipes from freezing.
While different parts of your system may need replacing throughout its life, you can expect the average sprinkler system to last for upwards of 20 years. During that time, you'll likely need to replace your sprinkler heads around the 10-year mark if using high-quality heads.
System maintenance can help save you a lot of money and water! Cracks in pipes can lead to costly leaks, and broken sprinkler heads can waste water and money. You could be losing up to 25,000 gallons of water and $280 over a six-month irrigation season! Now is the perfect time to spruce up your irrigation system.
Water will not freeze with the temperature air at or above 33 degrees, regardless of how far the wind chill is below freezing.
Freezing happens when the molecules of a liquid get so cold that they slow down enough to hook onto each other, forming a solid crystal. For pure water, this happens at 32 degrees Fahrenheit, and unlike most other solids, ice expands and is actually less dense than water.
