a    In the Northeast, before the first freeze, all irrigation systems must be winterized – meaning that the system must be completely drained and thoroughly dried to prevent damage to the irrigation system components caused by water freezing inside the pipes, sprinkler heads, and valves.  ALL water must be removed, because even a small amount could freeze and crack the pipes of your system.  Serious damage to the irrigation system could result if the system is improperly winterized.

a    When your lawn care professional winterizes your irrigation system, they will shut off the water to the system, and utilize a drain valve for attaching a compressed air hose downstream of the anti-siphon device.  Compressed air is used to blow all water out of the system one zone at a time.  After all water is removed from the system, water will be drained from the line between the backflow prevention device and the shut off valve.  

a    With proper winterization, your irrigation system will be safe and secure during the cold winter months, and ready for use when warm weather returns.
