Sprinkler Winterization in Lakewood, Colorado

Sprinkler Winterization

If you’re new to the Denverarea, you might not realize how important it is to winterize your sprinkler
system before freezing temperatures arrive. While some sprinkler systems offer “self-winterizing”
options, the truth is that anything short of a high-pressure blow out can leave traces of water in your
system which can freeze over and cause hairline cracks, weaken joints, and do real damage.

If you want your sprinkler system winterized quickly, reliably, and affordably, our Lakewood sprinkler
winterization experts are up to the job. Give us a call and let’s get you on the schedule!

Where do we offer sprinkler blow-outs?

We’re happy to offer winter sprinkler blow-outs in Lakewood, Arvada, Englewood, Littleton, Centennial,
and throughout the western Denver area. Visit our service area page to see the full list of cities.

Can I blow out my own sprinklers?

While many people in Colorado try to blow out their own systems, store bought air compressors don’t
always have the necessary strength for the job.
It’s also important to know what kind of sprinkler system you have before attempting a winter blow out.
Less common poly pipe systems can only tolerate 50 PSI before cracking, while PVC sprinkler sytems
should generally be blown out at 80 PSI. Compare this with the 30-50 PSI that is typically found inside a
system during normal operation.
Our technicians typically use trailer and truck-mounted compression systems that can deliver pressures
well in excess of 80 PSI when necessary.

Other Factors that impact winterization and freezing risk

Sprinkler pipes that are closer to the surface, or partially exposed, are generally at a higher risk of
freezing. As cold as it can get in Lakewood, the ground acts an an insulator, helping to protect deeper

Generally speaking, any sprinkler system pipes that are less than two feet deep are at risk of freezing. It
doesn’t matter if most of your system is sufficiently deep if an important part of your system is less
shallow—it will need to be blown out.

What Should I Do if I Can’t Winterize in Time?

If you forget to call an irrigation contractor before temperatures drop, consider protecting your exposed pipes with blankets or home insulation. Be careful though: this is not a long term solution, though it can get you through a new nights of harsh freezing.

It’s also worth mentioning that shallow, but not exposed pipes may not be frozen during the first freeze or two of a season. It can take several nights of freezing temperatures for the freeze to reach below the top layer of soil.

Do I need to shut my sprinkler timer off in winter?

For many sprinkler timers, yes. You can leave it plugged in (or leave the battery in) and leave it exactly where it is—just be sure to turn the timer to the “off” position.

Smart sprinkler timers, such as the Rachio controller, do not need any manual intervention.
