Pentair Water Treatment: The Parent Behind Fleck, Pelican, and EcoWater
Pentair plc (UK registered, US operations headquartered in Aurora, Illinois) is the largest water treatment company in the US, operating through subsidiary brands rather than under the Pentair consumer name. Pentair owns Fleck (control valves), Pelican Water (residential filtration/softening), EcoWater Systems (OEM manufacturer for Whirlpool and WaterBoss), and Codeline (commercial pressure vessels). When you buy a Fleck, Pelican, Whirlpool, or WaterBoss water softener, you are buying a Pentair product.
Pentair Commercial Water Softeners
The Pentair brand is used directly for commercial and industrial water treatment equipment — Pentair Fleck 2510SXT commercial valves, Pentair Twin-Alternating systems (100,000+ grain commercial softeners), and Pentair whole-building systems for food service, hospitality, and light industrial. These are dealer-installed commercial systems not available through consumer retail channels.
