The importance of proper winterization and how a professional seasonal irrigation shutdown service to prevent damage and ensure peak system performance when spring rolls around can not be overstated.
Even though irrigation pipes are installed 8 to 12 inches into the ground when the surface freezes it’s not uncommon for frost to reach 3 to 4 feet below. If an irrigation system is not shut down before temperatures drop below 32 degrees it can start a catastrophic chain reaction. First, the backflow preventer freezes, and then water left in the system solidifies, ultimately causing the pipes to burst, “killing” your system and costing you much more to repair, than it would have to prevent.
