Sprinkler Blowouts and Winterization
We are experienced, insured and our sprinkler blowouts come with a worry-free spring start up warranty! (Note: Warranty is only valid if the blowout is done before the first hard freeze of the year)
What is a Sprinkler Blowout and Winterization Service
Blowing out sprinklers is where a professional will attach an air compressor to the system and literally “blow out” the water from the lines, pipes and other parts.
A professional knows how much volume and pressure to use when blowing out sprinklers, as many do-it-yourselfers typically use an insufficient volume of air and after having forced some water out, the air will ride over the top of the remaining water. This results in the remaining water draining into low spots and subjecting the system to freeze damage.
Sprinkler pipes and backflow assemblies are at risk of freezing and breaking when temperatures drop below 32 degrees Fahrenheit. Immediate damage can occur to exposed pipes and sprinkler apparatus with the first freeze of winter. Further damage can result as extended freezing temperatures and wind chill conditions cause the soil to freeze at the same depth as the underground pipes. In many cases, homeowners are not aware that their pipes have sustained damage until they begin watering in the spring and discover leaks in their yards!
Not every company uses the same equipment. There are many types of air compressors. We use large diesel and gas powered compressors. The pressure is not excessive, but the amount of air is constant even with a large commercial irrigation system. When we arrive, we turn off the water supply to the sprinkler system, open any system drains, connect the air compressor to the system, blow out all of the lines, and open any drains on the outside of the house. Lastly, we set all valves on the pressure vacuum breaker to the positions that they need to be in for the freezing weather.
A properly winterized sprinkler blowout can be the difference between an easy spring start up and weeks if not months of problems the following season.
Frequently Asked Questions
No, you do not need to be home at the time of service. If you are not going to be home please:

You only need to have your sprinkler system winterized once a year. Make sure to winterize your system before the seasons first hard freeze. Thereafter, there are no guarantees or warranty that all the water can be flushed out of your system and you will not sustain costly damage. Just because you did not blow them out during the first hard freeze, get them blown out as soon as possible. The longer it freezes outside the farther down the freeze travels in the soil. If you do not blow them out you are virtually guaranteeing a disaster which will cost you a lot of money to repair. In some cases, the entire sprinkler system may have to be replaced.
