One winter’s chill can kill an irrigation system. The importance of proper winterization and how a professional seasonal irrigation shutdown service 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 and the need for costly repairs.
