Winterizing your sprinklers without a pump involves manually draining them and using compressed air to blow out remaining water. First, shut off the water supply and open the drain valves to let water out. Then, connect an air compressor to the irrigation system and blow out the water from each zone sequentially. Ensure to keep the air pressure below 50 PSI to avoid damaging the system. Lastly, open the test cocks on the backflow device to release any trapped water. This method prevents freezing and cracking in the pipes during winter.
