Even a little bit of ice in one spot will destroy the line over time. When the water freezes and expands, the PVC pipe will likely burst in multiple places. Furthermore, frozen water trapped in the backflow assembly will cause destruction to the internal components of the pipe. This kind of damage would cost much more than the cost of having All Terrain do a professional sprinkler blowout from Fort Collins to Boulder and anywhere in between.
Okay, so you have any auto drain sprinkler system. When you turn off the pressure, the spring opens and allows the water to run out. Not a very efficient way to save money on sprinkler blowout costs if you ask us! Maybe you blow out your sprinkler system with the air compressor you use to pump your spray paint or nail gun.
Although the compressor you have at home may be great, it only offers a rating of CFM cubic foot per minute. Long story short, if you use the compressor you picked up at the local hardware store, you may have a ton of pressure, but it also leads to a lot of wear and tear on your system! Because that sounds less than fun, All Terrain has your back.
How does All Terrain Landscaping winterize your sprinkler system? The blow out method involves placing a small amount of pressure behind the sprinkler system using a commercial air compressor at only psi delivering CFM.
If this all sounds too complicated, hire a lawn irrigation professional to do the job. But whether you pay someone to do it or decide to do it yourself, it is very important not to put it off, so that watering plants next year isn't compromised. Don Adams, home and garden expert at Regional Foundation Repair , explains that 'it might seem complicated when you first begin to winterize your home irrigation system, but it is cheaper and less work than having to replace a whole new system six months later.

After some time, the airflow should become quieter as all resistance is blow out of the irrigation system.
At the sprinkling outlets, the pressurized air should flow out freely once all the obstructions, namely water and pipe-lining residue, have been blown out of the pipes by the force of the air pressure. With that process now complete in the farthest zone, it is now time to repeat this process on the next area inward. Once you completely blow out the farthest zone and have seen the initial effects of pressurized air on your piping system, move the process to the next zone.
The time that it takes to complete the second zone should roughly be the same as with the prior zone. This time, however, you should have a better idea of what to look for and listen for while the blow out is in progress.
As the air compressor blows through the second zone, check the monitor once again to make sure that the pressure level does not exceed the maximum capacity of the machine. If this second zone contained a higher amount of trapped water beforehand, the process might be more intense this time around as the water is forced out of the sprinklers.
Wait for the process to finish. When it becomes apparent that the sprinklers in this zone are only passing compressed air, it will then be time to move on to the next zone. After you complete the second zone, the steps should be easy to remember.
Move the process to the third zone inward and allow the pressurized air to enter into this part of the system. Watch the sprinklers in this zone to monitor the level of activity. Certain sprinklers will spout water as if the pipes are being blown out by forceful air pressure.
This is a healthy development, as it proves that the pipes are being cleared of all the water and residue that would not drain naturally when you first shut off the system. Overall, each zone should require approximately two minutes of pressurized air to be cleared of lingering water and residue. In some zones, you might need to repeat the process once or twice to clear the pipes fully.
Once a zone has undergone the blow-out process for two minutes or more, the sprinklers in that section should be completely clear of lingering water. After you apply the pressurized air to the pipes in the final zone, you can mark the whole process as finished when the applicable sprinklers stop blowing out water.
At this point, you should cease the blow out altogether, as pressurized air could put stress on the inner linings of clean, dry pipes. From here, you can be confident that your pipes will be safe from water-related traumas during the winter months. When you reactivate your sprinkling system the following spring, the sprinklers should come back on after months of disuse without any performance issues. With the blow out completed across the entirety of your irrigation system, it is now time to disconnect the hose from the bib and the now-deactivated air compressor.
During this step, make sure that any lingering air pressure is released from the line, as it could ultimately prove problematic if a trapped pocket of pressurized air remains trapped indefinitely. Unplug the air compressor from its power source and return the unit to its normal storage space.
Roll up the hose and return it to the place where you store the attachments for your air compressor. As you wrap up the job and call it a day, be sure to check the instruction manuals that came with your equipment. If there are any recommended steps to follow for the compressor or any attachments, complete them as listed. 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 Role of Air Compressors in Blowing Out a Sprinkler System With an air compressor, you can effectively clear out your irrigation system of lingering water at the end of each warm season. Step by Step Guide on How to Blow Out Your Sprinkler System with an Air Compressor The following is a guide that will teach you how to winterize your irrigation system at the brink of autumn before you put your sprinklers away for several months. Turn Off the Water To successfully blow out your irrigation system, you will first need to shut off the water supply and perform a preliminary draining of the pipes.
To ensure proper system health, you should first drain the pipes naturally and then conduct a blow out 2. Open Hose Bibs, Drain Water Once you have shut off the water supply to your irrigation system, the next step is to open the hose bib located on the mainline of the sprinkler. Test the Air Compressor 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. Prepare the Hose Once you have the psi set on your air compressor, shut off the machine and close its valve.
Attach the Hose With the hose and the air compressor now ready, attach the hose to the bib located on the mainline of the sprinkler system. Activate the Air Compressor With the hose properly connected between the air compressor and the irrigation system, it is now time to turn on your air compressor.
