As temperatures drop all over the country, the time comes for home and business owners in many states to begin the process of winterizing their sprinkler systems. There are a few steps required to complete this process in a way that will protect your irrigation system throughout the freezing temperatures winter often brings, but perhaps the most important of them is the sprinkler blowout.
A blowout is exactly what it sounds like—before the water in your sprinkler lines freezes, the water still lingering inside those lines needs to be blown out to prevent freezing. While completing this process doesn’t necessarily have to be complicated, it certainly can be, which is why a respected local irrigation contractor like A-Team Irrigation offers the service for a reasonable price.
Of course, if you’d rather try it yourself, just make sure you’re doing it safely and correctly.
What Happens When Water Freezes inside a Sprinkler Line?
When water freezes, it expands, and since there are several components in a modern irrigation system that rely on plastic parts, that expansion can do irreparable damage to sprinkler lines and other plastic parts in your irrigation system. The added pressure inside those lines can cause them to burst, and since many of those sprinkler lines are buried under ground, the repairs are costly and aesthetically not pleasing.
This is the major reason why the professionals at A-Team irrigation recommend that home and business owners winterize their sprinkler system. It is much easier to take care of this task in the fall than it is to deal with expensive and extensive repairs in the spring.
How to Complete a Sprinkler Blowout
- Shut off the water running to your sprinkler system. You will have a main water shut-off in your house as well as a separate shut off with an air compressor hookup attached to it. There’s no need to shut off all the water in your house. Just turn it off there at the source to the sprinkler.
- Attach your air compressor hose to the hookup beneath the water control leading out to your sprinkler system, and turn on your air. Make sure you’ve got all the converter pieces you’ll need to get that compressor hookup linked to the air compressor itself.
- Set the system to run each zone in your system to run for four or five minutes. Every system is different, so consult your handbook if you need any guidance in how to complete this.
- You will see your sprinklers outside shoot out their remaining water in bursts. Let it continue to run until all you see/hear is air coming out of the sprinkler heads.
