Cracked PVC manifolds are a common form of irrigation freeze damage in Michigan.
Why PVC cracks
Water trapped inside rigid PVC expands as it freezes. The manifold, fittings, unions, and valve connections may split because they cannot absorb the expansion.
Common signs in spring
- Valve box flooding
- Visible cracked fittings
- Low pressure
- Water spraying when the mainline is opened
- Multiple leaking manifold joints
Prevention
Professional winterization removes water from vulnerable zones and manifold plumbing before sustained freezing conditions arrive.
