⚠️ IMPORTANT: KIT LISTING
This listing is a kit, not a single component. Confirm all kit contents against your SunTouch system's parts diagram before installation.

Pro Tip

Pentair is often considered the "gold standard" for pool professionals, and for good reason. Founded in 1966 (originally by five inventors making high-altitude balloons!), the company has evolved into the global leader in smart, sustainable water solutions. For the DIY homeowner, Pentair represents the intersection of rugged durability and silicon valley-tier technology. They pioneered the Variable Speed Pump revolution with the IntelliFlo®, saving American pool owners millions in energy costs. Today, their ecosystem focuses heavily on automation, allowing you to control your pump, heater, lights, and chemistry from a single app. While they are a favorite among professional builders, their "EC" (E-Commerce) line of equipment allows homeowners to access pro-grade technology with valid warranties for DIY installation.
