To winterize sprinklers effectively, you'll need an air compressor with a capacity of at least 50-100 liters (13-26 gallons) per minute output rate. It's crucial to use a compressor that can steadily maintain 40-50 PSI for residential systems, ensuring all the water is expelled from the pipes. Opt for a compressor with a 5-10 CFM (cubic feet per minute) rating to efficiently handle the job without causing damage to the system.
