Air compressor for blowing out sprinkler system FAQs
What size air compressor do I need for blowing out sprinklers?
For you to properly and safely blow out your sprinkler system without causing any damages to the plumbing, you need an air compressor that provides at least 20 cfm (cubic feet per minute.) However, most irrigation experts and professionals do recommend you use at least 50cfm. And you know what, most air compressors do list the ideal cfm rating on the tank side.
If you’re using an air compressor rated 50 cfm to 100 cfm, you have the right-sized air compressor. However, you need to maintain an averagely 50 cfm for blowing out your sprinklers. But that depends on the number sprinklers you have and the size of your irrigation plumbing.
How many PSI do I need to run my sprinklers?
Getting the right air volume requires an air compressor that provides over 20 cfm and air pressure around 50 PSI. A rigid PVC-pipe system needs a maximum of 80 PSI, and a flexible black polyethylene pipe system needs a maximum of 50 PSI. That is why you need to use an ideal air pressure regulator to control it.
When should you blowout your sprinklers?
Blowing out your sprinklers requires the right timing. If you do it too early, your irrigation area might lose precious water needed for winter preparation. If you do it too late, your sprinkler system might damage, and you be forced into expensive repairs. It will help a lot if you do it when the temperatures start to fall. The best time is when the outdoor air temperature dips below zero degrees Fahrenheit.
What happens if you don’t winterize your sprinkler system?
During winter, any water resting outdoors freezes. If you forgot or decided not to winterize the sprinkler system, any remaining water in it freezes, from irrigation valves and pipes to the sprinkler heads. The freezing water expands, causing these parts to break or even burst, destroying your sprinkler system. That leaves you with expensive repairs, or even you may be forced to change the whole irrigation system.
How do you hook up an air compressor to a sprinkler system?
Hooking up an air compressor to a sprinkler system is a simple DIY process that requires you to follow some straightforward steps.
The first thing you want to do is charge up your air compressor; fill it with air.
- Close the compressor airflow valve and put on eye protection.
- Connect the fitting on the blowout adapter on your sprinkler line and connect the air compressor house there with the right fitting.
- Check the sprinkler control panel and manually open the furthest sprinkler zone.
How do you drain sprinkler lines?
Close your sprinkler system backflow valve and go back to the air compressor. Open the air compressor valve slowly and monitor the gauge to ensure it doesn’t exceed 80 PSI. Now you can open the additional zones and work slowly out. Blow them out until no water is running out of the sprinklers but air.
When should you drain your sprinkler system?
The best time is when the temperatures start to fall. It would be best if you did it before the first hard freeze. The best timing is when the outdoor temperatures go below 32 degrees Fahrenheit (0 degree celsius).
Typo in this article says “The best timing is when the outdoor temperatures go below 0 degrees Fahrenheit.” — probably want to do it before temps go below 32 deg. F
Thanks. It is now fixed.
Thanks for writing this detailed article. I’m interested in blowing out my own sprinkler system instead of paying a professional to do it every year. I’m a bit confused by the requirements for the compressor. You say that professional recommend at least 50 cfm (the manufacturer of my sprinkler system, Hunter, says to use a 80 – 100 cfm compressor and to never exceed 80 psi), but the recommended compressors are all much smaller (around 2.6 scfm). So will such a small compressor actually work to blow out my sprinkler system?
The airflow (cubic feet per minute-cfm) isn’t of much concern, so long as you have enough pressure, not exceeding the rated maximum. The reason professionals prefer the 50 cfm air compressor is that it can deliver enough airflow to force any water inside the sprinkler system quite well, without causing any damage. In the case of hunker sprinkler systems, what they are providing you with here is an air compressor ideal for most of their systems. You must understand that the sizing can be from 50 cfm up to 100 cfm. So, in general, their rating does fall under this coverage. Remember to not go over the 90 PSI for 50 cfm unit and not above 80 PSI if you decide to use an 80+ cfm model.
I bought the 6 gallon pancake Dewalt air compressor for a small sprinkler system. (Its just 2 zones.) If I run my air compressor several times for each zone, would that be enough? I read that even doing it several times still won’t solve the problem because of the small amount of air from the compressor? I’m not sure who to believe. Does every ounce of water need to be out of the sprinkler?
50cfm to 100cfm??? Did you mean psi???
