What is the full winterization procedure for a splash pad?
Quick answer
Drain all lines using compressed air at 30-50 PSI, blow out each zone individually, drain pumps and filters, remove and store sensors, wrap exposed valves, lock the control panel, and post a winter signage closure. Skipping any step risks $5K-$50K in freeze damage. Document with photos.
Winterization is the most important annual task in cold climates. The procedure: shut off the city water supply at the curb stop or main valve. Open every drain valve and zone valve, then connect a 30-50 PSI compressor to the highest point and blow out each zone in sequence until only mist exits. Drain pumps, strainers, and filters completely; remove drain plugs and store them in a labeled bag. Remove and bring indoors any flow sensors, pH probes, ORP probes, and chlorinator parts since they crack when frozen. Wrap exposed above-grade valves with insulated covers. Drain the surge tank and recirc loop. Lock the control panel and post winter-closure signage. Photograph everything for next-spring reference and insurance. Skipping a single zone can cause cracked manifolds and $5K-$50K in repairs. Most operators schedule winterization right after first sustained sub-40°F nights.
