If water collects in part of the sprinkler system that is deeper underground, it will be less effected by early shifts in temperatures. In warmer areas, the ground this deep may never freeze. But we don’t have that luxury in Wheat Ridge. Later in the winter, water in deeper pipes will eventually freeze and can burst those pipes, which are much harder to get at to repair.
Further, water drops will also get into the mechanics of the sprinkler system, the actual gears and sprinkler heads. While some of this water may evaporate before temperatures drop, if some remains, it will freeze and damage those as well.
Instead of a quick and simple blow-out process, you’ll need to dig to repair or replace pipes, replace sprinkler heads, even the control system. Avoid all of that headache and call the professionals for sprinkler winterization in Wheat Ridge.
