sprinkler Blowout

Sprinkler blowouts and timely winterization are crucial
for protecting your irrigation system from freezing weather damage.

Winterize Your Sprinkler System
Before the Freeze

Sprinkler blowout, also known as winterization, is the process of evacuating all of the water from your irrigation system to prevent damage caused by freezing water. The main piece of equipment used for this type of work is a professional-grade air compressor.

Not all air compressors are created equal. Many homeowners do attempt to blowout their systems with store-bought air compressors, only to find that the process can take up to ten times as long, with expensive consequeces. These products do not create the constant air flow needed to guarantee all the water is cleared, which then freezes and expands inside the system pipes, causing them to crack.

With Advantage Irrigation, we begin the process of winterization by shutting off the water off that supplies the irrigation system. We then hook up a hose from our large air compressor and blow a powerful stream of air through the lines, which, in turn, pushes the water out. Finally, we power down the irrigation controller. This is done in the Fall, before the freeze of Winter arrives.

Advantage Irrigation expertly performs sprinkler blowouts and winterizations. Based out of Medway, MA, we also serve Medfield, Brookline, and beyond! Our unique process includes longer blowouts to eliminate the chance of freeze damage, a routine check of the backflow prevention system, and an audit of items to inspect or repair come Spring – there’s no sense making repairs before a New England winter hits. We’ll be ready in the Spring for your sprinkler system turn-on!

Frequently asked questions

A sprinkler blowout is a process in which compressed air is used to clear all water from your irrigation system. It’s necessary before freezing temperatures arrive, as residual water can freeze, expand, and cause significant damage to the pipes and other components of your sprinkler system.

The best time to winterize your irrigation system is in the fall, before the first hard freeze. The exact timing can depend on your local climate, but generally, it’s a good idea to have your system winterized by the end of October in most northern climates.

While it is possible to perform a sprinkler blowout yourself, it’s generally recommended to hire a professional. The process requires specialized equipment and knowledge to be done correctly and safely. If not done properly, you risk damaging your system or potentially causing personal injury.

In addition to performing a sprinkler blowout, winterizing your system typically involves shutting off the water supply to the irrigation system, draining any remaining water, and insulating any above-ground components. A professional will also check for any necessary repairs so that your system is ready to operate efficiently when spring arrives.
