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.

3 Types Of Sprinklers Overview

There are only 3 types of Lawn Sprinkler heads. The main function for them is to water Lawn and vegetation.

1. Pop Up Sprinklers: spray in a fan pattern and are generally for smaller areas like park strip

2.  Gear-Driven Rotors: have one stream and move back and forth covering a bigger lawn area. They spray from 20’-50’ and can be customized to spray in any given pattern. They can spin all the way up to 360 degrees.

3. Impact Rotors:  have one stream coming out and move in a circle. The main benefit of an impact rotor is that it can take on dirty irrigation water with a lower chance of breaking and plugging up.  They are less efficient and use more water, but use basic technology that makes them last much longer.

When soil temperatures reach around 40°f – 50°f, lawns will begin going into dormancy. Lawns will start going a greenish yellow and will stay that way till spring. According to Central sod farms (1), Inc. the lawn/grass does this to preserve energy.

2) Q. Why Winterize my lawn Sprinklers?

Every sprinkler system needs to be winterized. Getting your lawn sprinkler system winterized for the cold weather in the Northern United States is crucial for keeping your lawn irrigation system ready for spring and summer next year. This will help with costs of sprinkler repair. To winterize the water must be blown out of your lawn sprinkler system to prevent freezing.

When water is expanded by 10% as it freezes this energy has to go somewhere and it will crack the hardest of materials. Ice will break any part on a sprinkler system including steel pipes and backflow devices, causing a lot of damage and costing money in the spring for sprinkler repair work.  Water can move a 10-15 ton of rocks and a 3 inch solid steel ship hull when frozen. Your sprinkler system has no chance with this amount of power (2). That is why you need to remove water in your lawn sprinkler system in the Northern United States.

Here at Sprinkler Master in the Northern United States we are professional sprinkler technicians. All we do is repair sprinklers, and the majority of sprinkler repair is caused by sprinklers not being winterized, or not doing it properly.

3) Q. How to winterize a sprinkler system

Can you do it yourself or have a friend do it? Yes, with the proper tools, and knowledge. The majority of sprinkler repair in the Northern United States comes from sprinkler systems not being blown out correctly.

The right tools:

The major key when winterizing a sprinkler system is having a large volume of air go through the system.  To do this the common person needs to rent an air compressor for around the same price as Sprinkler Master charges to come do it for you. We are licensed, insured and backup our work. Most sprinkler systems cost around $60 to winterize.

Can I use my home or small air compressor?  When people use their small air compressor almost always it does not work and will take most of your day up. You need around 80-100 cfm (3), an average residential air compressor does 2 cfm. Blowing it out with a small compressor is taking a big risk(4).  To blowout your system it does not matter if your air compress goes up to 100-200 psi you will need air volume and psi to push all the water out of the sprinkler pipes (5).
