Step 1


We recommend for this job to find another small compressor that has a volume rating above 2cfm to easily fill the HoseAir Tank for multiple blowout sessions. Since sprinkler systems require high volume (20cfm at least) to successfully winterize a system, our HoseAir Tank adds an additional 10-gallons of air volume to help maintain a longer lasting CFM rating at 50psi. Each specific zone typically requires an average of 2-3 air tank fill ups to successfully eliminate all the water from the lines. The HoseAir tank is rated for 150psi but we recommend filling the tank up to 120-130psi. What about regulating PSI?? HoseAir has equipped a built in preset regulator that controls the outflow of the tank to a maximum of 50psi. This preset pressure regulator takes the stress and worry out of over pressurizing and damaging your water lines, all while still providing the adequate pressure to push the water out. Our goal is to take the fear out of winterization.

Step 2


Whether it’s in your basement or garage, you will have to find the location to shutoff the water supply to your sprinkler system. Once completed take a bucket under the drain valve and release the excess water sitting in the line. Don’t forget to close the relief valve before hooking up the air.

Step 3


There are multiple options when hooking air up to air to your sprinkler system. Most likely if you have had your system blown out before, you are already aware of the air hookup location. Whether you have a quick connect air port or just the option to hook directly to your relief drain, we have made the HoseAir Tank fittings capable of hooking up to any standard garden hose.

Did you know: The average garden hose is rated for 200psi. Meaning it can easily handle your 50psi air push!

We also include a conversion fitting to transfer the end of the garden hose thread type to a M-style quick connect hookup. No need to buy another expensive air hose. Now you can directly hookup to your system or easily find a fitting that fits your custom setup.

Step 4


Now it’s time to pressurize the manifold. First, simply release the HoseAir Tank air valve into your hose. This process will pressurize your system and provide air pressure up to each one of the sprinkler zone valves. Next, it’s time to release the air to a desired zone.

There are three ways to release air to sprinkler heads…

1. (Least recommended) Manually turn on each valve. Be careful not to over-loosen to prevent the solenoid from coming off and damaging the valve.

2. (Second best option) Go directly to your sprinkler control box and manually turn the zone on from the panel.

3. (This is our favorite) If you have a WIFI controlled system, this is the best option. We like to watch the blowout process close up to the zone so we can easily see if we need another tank refill or whether the blowout session was a success.

Once the heads lose pressure it is necessary to quickly shut off the valve to stop air flow and to conserve the remaining air inside the tank. This tip will allow for a quicker refill time.

Hands Free Process: If your are able to keep your compressor hose attached to the HoseAir Tank, you don’t have to worry about manually refilling the tank each refill time. Just listen for the compressor to kickoff to know that your HoseAir Tank is recharged and ready for another blowout session. Just make sure your air compressor regulator is turned up to the 120-130psi to completely fill the HoseAir Tank to the desired psi.

Step 5


Repeat blowout sessions until mist is cleared and the heads won’t stay up. Once you have gone through each of your zones you are done! Now embrace your accomplishment!
