To bleed air out of a sprinkler system, first, locate the main valve and turn off the water supply. Find the manual bleed valve, which is often situated near the main valve. Slowly open the bleed valve to allow air to escape — you'll hear a hissing sound. Once water starts to come out, close the valve. Repeat this process for each zone in your system to ensure all air is removed. Remember to turn the water supply back on once you're finished.
