Can I blow out my sprinklers myself?
High pressure and low volume won’t get the job done. You want high volume and low pressure to eliminate damage and completely blow out your sprinklers.

What air compressor do I need to blow out sprinklers?
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 manually winterize my sprinkler system?
How To: Winterize Your Sprinkler System STEP 1: Turn off the main water supply and if present, the backflow preventer. STEP 2: Drain any water remaining in the irrigation system. STEP 3: Open all drain valves. STEP 4: Consider hiring a pro (optional, but recommended).
Can you blow air through a backflow preventer?
Compressed air should not be blown through any backflow device. 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. Close the backflow isolation valves.
Why wont my sprinklers blow out?
Most likely, the air inlet valve is not sealing properly. When pressurized from the side marked “normal flow” (which is where your tap is), it should open the check valve, and also force the air inlet valve shut.
When should I blowout my sprinklers?
A good rule of thumb is to have your sprinkler system winterized in early fall, but we recommend keeping an eye on the weather, and ensure that your watering system is drained and blown out at least one week prior to the seasons first freeze.
Can a small compressor blow out sprinklers?
Portable, household air compressors will not have nearly enough power to blow out an irrigation system. Never try to fill up a compressor tank fully then release it all at once to make up for lack of air volume.
Can a 6 gallon compressor blow out sprinklers?
1. CRAFTSMAN Air Compressor, 6-gallon. The Craftsman electric air compressor is a great all-around machine, perfect for blowing out water from sprinkler lines, and we like it a lot. This craftsman’s 6 gallon tank capacity also makes it good value.
How do you blow out a sprinkler system with an air compressor?
Step by Step Guide on How to Blow Out Your Sprinkler System with an Air Compressor Turn Off the Water. Open Hose Bibs, Drain Water. Test the Air Compressor. Prepare the Hose. Attach the Hose. Activate the Air Compressor. Open the Compressor Valve. Monitor the Blow Out Process.
Is a 20 gallon air compressor big enough to blow out sprinklers?
Its output is particularly impressive, measuring 7.9 CFM at 40 PSI and 6 CFM at 90 PSI. That very strong output is great for fully clearing sprinkler system lines through the blowout method. Its 20-gallon air tank can hold more than enough to winterize a lawn sprinkler system.
When should I worry about sprinkler system freezing?
When temperatures start to fall, it’s time to consider winterizing your sprinkler system. Your lines must be drained or blown out using an air compressor before the first hard freeze. A hard freeze is when then outdoor air dips below 0 degrees Fahrenheit.
How large of an air compressor do I need?
As a guideline, most air compressors meant for powering tools fall in the 10 to 110 CFM range. Note whether the CFM rating is for 100% duty cycle, as many continuous-use tools are still rated as if you’re only using them 50 to 60%—you will need a higher CFM rating if you don’t want to stop regularly.
How much does sprinkler blowout cost?
Typical costs: Hiring a landscaping or sprinkler company to winterize/blow out a sprinkler system can cost $30-$160 or more, and typically costs about $55-$85 for an average home, depending on the number of irrigation zones in the system, the local cost of living and the month the work is done.
