To drain a sprinkler system that is freezing, start by turning off the water supply to the system. Next, open the manual drain valves located at the lowest points of the piping. For systems with automatic drain valves, these should open on their own once the pressure drops. If your system is equipped with a blowout port, use an air compressor to blow remaining water out of the lines. Always wear protective gear to avoid injuries. Remember, removing water from your sprinkler system prevents freeze damage and costly repairs.
