The Danger of Not Winterizing Your Sprinkler System

If you forget about sprinkler blowout, you run the risk that water will freeze in the irrigation valves, pipes, and sprinkler heads. When water freezes it expands causing parts of your system to explode and destroy your sprinkler system.

When water freezes inside the pipes and valves of your irrigation system, it expands and exerts pressure on the components. This can lead to cracks, leaks, and even ruptures in the pipes and valves. The resulting damage might necessitate expensive repairs or replacements.

The water trapped within sprinkler heads can freeze and cause the internal components to crack or break. When the ice expands, it can shatter the delicate mechanisms within the sprinkler heads, rendering them useless and requiring replacements

As water freezes and expands, it can create pressure within the irrigation system. This pressure can build up to dangerous levels, potentially causing fittings, joints, or other weak points in the system to burst open, resulting in water leakage and substantial damage.

The damage caused by frozen water expanding within the irrigation system can lead to significant repair costs. Homeowners might have to deal with replacing pipes, valves, and sprinkler heads, as well as fixing any resulting landscape damage due to leaks or flooding.

If the damage from freezing water is severe enough, your entire irrigation system might become inoperable. This could lead to a lack of proper water distribution to your lawn or plants, potentially impacting their health and causing the need for further investment to restore the system’s functionality.

Can I do sprinkler blowout my own sprinkler system?


If you follow the principle of high pressure and low volume, it will not help.

You want high volume and low pressure to eliminate damage and completely blow out your sprinklers. Additionally, please don’t mistake air pressure and water pressure. As you can see, blowing out your own sprinkler system isn’t as simple as pushing air through it. While you can blow out your system yourself, it’s a good idea to hire a contractor to winterize your sprinklers.

Blowing out your sprinkler requires mechanical and technological knowledge dealing with air volume, air pressure, and figuring out the ratio between the two. You can quickly ruin your lawn sprinkler by miscalculating the air volume or using the wrong size air compressor for sprinkler blowout.

If you decide to blow out the system on your own, make sure you know:

  • The gallons per minute (GPM) flow through each irrigation zone. The GPM helps you know what size air compressor you need for the job.
  • If you have a backflow preventer, you need to blow out the preventer too.
  • Air volume is just as vital for sprinkler blowout as air pressure. You only want to blow out your sprinkler with the right amount of air volume.
  • If you don’t use enough air volume after flushing some of the water out of the system, the air will rise to the top of the water. This air movement causes water to drain into the bottom. And if water flows down, it’ll freeze and put your system in danger of damage.
  • You should only blow out your system one zone at a time.
  • If you blow out more than one zone at a time, You run the risk of overheating the pipes and fittings as well as melting them. And if your pipes and valves don’t burst right now, they may still be damaged.
  • If the sprinkler heads stay above ground after you’re finished blowing out the system, you know that you used the right air compressor size for the sprinkler blowout.
