With as much water naturally drained from the pipes as possible, now is the time to turn on your air compressor and get it ready for the task ahead. The amount of power that you will ultimately need to blow out the sprinkling system may depend on the types of pipes involved. Congratulations – you now know exactly how to blow out a sprinkler system with an air compressor and can complete this process on an annual basis to protect your sprinkler system from damage. Every year as winter approaches, you should have an air compressor on hand to blow out any lingering water from the pipes of your irrigation system.
The CFM of the compressor I have it about 4cfm. Based on how blowing out the lines went, if’s time for a higher CFM compressor. I’m in no hurry to replace the compressor – I really am just trying to discern what CFM compressor I would need to run the tools and blow out the sprinkler system. Using the air compressor, I blew out each zone to where all the heads were simultaneously blowing out just air rather than just mist.
Learning how to properly using an air compressor to blow out sprinklers means understanding how to put out just the right amount of pressure into your sprinkler lines one zone at a time. With enough experience, you will soon understand how to spread out the load needed to blow out just the right size of your sprinkler system using the air compressor that you have on hand.1. To properly blow out your sprinkler system, you may need to have an air compressor that can sustain enough volume to blow air into a section two minutes at a time, or even longer.
Skip to main content Sprinkler systems need to have all the water blown out of them before the winter freeze. If you have an air compressor you can do the job yourself and save the service fee. Introduction Save big bucks by blowing out the sprinkler system yourself.
how to attach air compressor to sprinkler system Related Question:
Where should a sprinkler compressor be placed?
To start the blow out, shut off the irrigation water supply and, with the compressor valve in the closed position, attach the air compressor hose to the fitting. Activate the station on the controller that is the zone or sprinklers highest in elevation and the furthest from the compressor.
Do you need an air compressor to winterize sprinkler system?
We have used a variety of compressor sizes to winterize our sprinklers over the years. You need a compressor that has either enough volume or large enough motor to fill your system with pressurized air. A compressor size of 4-6 gallons should be enough.
How do I winterize my sprinkler system without a blowout?
Not all systems need to have the water blown out of them. You can winterize a sprinkler system without an air compressor if all of your irrigation lines are buried at a slight downhill slope. Simply shut off the main water supply to your system and open the drain valves at the end of each zone.
How big of an air compressor do I need to winterize sprinklers?
The minimum volume an air compressor must be able to provide to properly blowout an irrigation system is 20 cubic feet per meter (CFM). Still, many professionals recommend up to 50 CFM at under 50 PSI for optimal performance, assuming the water lines are less than an inch in diameter.
What size of air compressor do I need to blowout a sprinkler?
To properly blow out a sprinkler system, your air compressor needs to provide at least 20 cubic feet per minute. Most irrigation professionals recommend using at least 50 cubic feet per minute.
Is SCFM the same as CFM?
SCFM and CFM are both essential values that indicate the airflow rate in a compressor. SCFM measures this value based on ‘ideal’ temperature and pressure conditions, while CFM measures the ‘actual’ air flow rate. CFM is the recognized value for measuring the airflow rate in the United States.
