Why Winterize Your Sprinkler System?

  1. Prevent Freezing Damage: When water freezes inside your sprinkler pipes, it expands, causing pipes to crack or burst. This can lead to extensive damage and costly repairs.
    1. Preserve Your Investment: Your landscaping is a valuable asset. Proper winterization helps protect it by ensuring your sprinkler system doesn’t harm your lawn and garden.
    1. Save on Spring Repairs: By taking preventive measures now, you’ll avoid the headache and expense of repairing or replacing your sprinkler system in the spring.

When to Winterize Your Sprinkler System

The ideal time to winterize your sprinkler system is before the first hard freeze, usually in late fall. It’s important to act before temperatures consistently drop below freezing, as this can prevent damage to your system.

How to Winterize Your Sprinkler System

Follow these steps to properly winterize your sprinkler system:

  1. 1.Turn Off the Water Supply: Locate the main shut-off valve for your sprinkler system and turn it off. This will prevent water from flowing into the system.
  2. 2.Drain the System: Open all the drain valves and low-point drains to allow water to drain from the pipes. Be sure to open all manual drain valves and automatic drain valves as well.
  3. 3.Blow Out the Pipes: To remove any remaining water, use an air compressor to blow out the sprinkler lines. Begin with the zone farthest from the compressor and work your way back. Gradually increase the air pressure to avoid damaging the pipes. Keep blowing out the lines until no water comes out of the sprinkler heads.
  4. Clear the Backflow Preventer: If you have a backflow preventer, ensure it’s properly drained to avoid freezing damage.
  5. Insulate and Protect: Insulate any above-ground pipes, valves, and backflow preventers with foam insulation or insulated tape. Cover above-ground components with insulated covers to protect them from extreme cold.
  6. Store Equipment: Properly store sprinkler heads, hoses, and other removable components in a dry, frost-free location.
  7. Professional Inspection: Consider having a professional technician inspect your system to ensure all components are winter-ready and to identify any potential issues.


Winterizing your sprinkler system is an essential task to protect your investment and prevent costly repairs. By following these steps and acting before the first hard freeze, you’ll ensure your sprinkler system remains in top shape and ready to deliver lush, green lawns and vibrant gardens when spring returns.

Is it too late to winterize your sprinkler system?

   Is it too late to winterize your sprinkler system?  

The answer is no! Not until we have a deep long freeze. 

 With it already getting below freezing, the cold has not yet caused too much damage to lawn sprinkler systems. The bad news is, you are running out of time. 

The colder it gets the lower the frost goes in the ground and damages more of your sprinkler system.  Right now your sprinkler system has not had much damage because only a small part of it is above the ground.  Bellow the ground the frost line has not hit the sprinkler system yet in most areas.

  How does damage occur?  It happens from water freezing and expanding about 10% of its size causing things to split and crack.   The majority of sprinkler repair we do in the spring is caused by not having a sprinkler system properly winterized.  We can still blow out your water in your sprinkler now.

During the Fall season,  the cold temperatures start to penetrate the soil and begins to freeze the ground. The cold temperatures have not yet penetrated to the depth that would hurt the majority of your sprinkler system.  This depth is known as the frost line. The frost line is the depth in which everything above it freezes. Sprinkler lines are typically between 6 to 12 inches deep, the frost line varies goes much deeper than sprinkler system pipes. To avoid damage, pipes with water in them need to be buried below that line, such as your water line to your home.


 In Northern Minnesota, the frost line can reach 100 inches and Northern Texas it can reach 20 inches. If the frost line hits your underground pipes in your sprinkler system it could total your sprinkler system, causing lots of damage.

      Once the lines freeze, the water turns into ice and expands, the expansion causes damage.  

To avoid the damage you need to winterize your sprinkler system.
