Sprinkler Winterization & Blowouts in St. Clair Shores, MI
I’ve winterized systems across St. Clair Shores for decades—canal homes off Jefferson and the Nautical Mile, streets near Harper and Little Mack, and neighborhoods between I-94 and the lake. I handle both city-water and lake/pump setups. My method is simple and safe: 50–60 PSI with high CFM, short passes per zone, and I leave the drain plug off or partially threaded so any weeping main shut-off drains out instead of back into the system.

How I Winterize
- Shut off & inspect — supply/backflow, drains/low points, zone order.
- Hook up safely — connect downstream of the backflow and run 50–60 PSI with high CFM.
- Zone passes — farthest first, 60–120 seconds until fine mist; pause between zones.
- Backflow & drains — purge test cocks; open manual drains; leave the drain plug off or partially threaded.
- Controller — City-water can stay ON. Pump/lake/well: pump-start disabled.
- Winterizing Report — paper report + text notes; check the drain area in 24–72 hours.
