Quick answer: Waxhaw can experience freezing weather, so irrigation systems with water trapped in vulnerable piping, valves or above-ground components can be exposed to freeze damage. Whether a particular system should be blown out depends on its design, drainage and exposed components.
Why irrigation systems can be vulnerable
Water expands when it freezes. Water trapped in components with little room to expand can crack fittings, valves or other irrigation parts.
Does every system drain itself?
No. System design varies. Automatic or manual drains may remove water from some portions while leaving water in low spots or components. Do not assume shutting off the controller removes water from the system.
What winterization is intended to do
Professional winterization reduces water left in irrigation piping and zones before sustained freezing conditions.
