Use a wrench or adjustable pliers to tighten the fitting if necessary, but avoid over-tightening. Refer to the manufacturer’s instructions for both the air compressor and the sprinkler system for specific connection guidelines.
Setting the Air Pressure
Once the air compressor is connected, it’s crucial to set the air pressure to the appropriate level. Consult your sprinkler system’s documentation or a plumbing professional to determine the maximum recommended pressure. Generally, a pressure of 50-80 PSI is sufficient for most residential systems. Start with a lower pressure and gradually increase it until you see water being ejected from the sprinkler heads. Avoid exceeding the maximum recommended pressure, as this can damage the pipes, valves, or sprinkler heads. Most air compressors have a pressure regulator that allows you to adjust the output pressure.
Blowing Out Each Zone
Now you can begin blowing out each zone individually. Turn on the air compressor and allow it to build up to the set pressure. Open the valve for the first zone you want to blow out. Observe the sprinkler heads in that zone. Initially, you will see a large amount of water being ejected from the heads. As the water is cleared, the mist will gradually decrease. Allow the air to flow through the zone for 2-3 minutes, or until only a fine mist of water is being ejected. Close the valve for that zone and repeat the process for each remaining zone. It is important to blow out each zone thoroughly to ensure that all water is removed from the pipes.
Repeat the Process (If Necessary)
For larger or more complex sprinkler systems, it may be necessary to repeat the blowout process to ensure that all water is removed. After blowing out all zones once, allow the system to rest for a few minutes, then repeat the process for each zone. This can help to remove any remaining pockets of water that may have been trapped in the pipes.
