In regions where the frost level falls below the depth of the installed piping, it is common for systems to be “winterized”. Several methods can be used to drain the water from the system. If compressed air method is used, it is recommended that a qualified licensed contractor perform this type of winterization.
WEAR ANSI APPROVED SAFETY EYE PROTECTION! Extreme care must always be taken when blowing out the system with compressed air. Compressed air can cause serious injury, including serious eye injury from flying debris. Always wear ANSI approved safety eye protection and do not stand over any irrigation components (pipes, sprinklers, and valves) during blow out. SERIOUS personal injury may result if you do not proceed as recommended.
