To winterize an irrigation system without an air compressor, you must manually drain the water from the pipes, valves, and sprinkler heads. First, shut off the water supply to the irrigation system. Open all manual drain valves, starting from the highest point and working your way to the lowest, to allow the water to flow out by gravity. If your system is equipped with check valves, you might need to pull up on the sprinklers to let water drain out of the bottom. Lastly, don't forget to drain any above-ground piping and open the test cocks on the backflow device. This method ensures that your system is free of water that could freeze and cause damage during the winter.
