Winter Is Approaching... Is Your Irrigation System Ready For It? If you've not yet scheduled the winterization of your irrigation system with Aqualon, now is the time to do so! Winterization prevents freeze-damage to pipes, sprinklers and backflow preventers; any irrigation device that's receptive to freezing (i.e. anything with water in it above the freeze line). Aqualon Irrigation Specialists will use a compressor to relieve your irrigation system for the winter. We'll turn off your system at the water source, and turn off your controller. Backflow preventers are drained, winterized and taken to our climate-controlled warehouse for storage until spring. Call Aqualon Irrigations Specialists NOW and get ready for winter!
