Note: Quantity required varies by pump series — 1 washer (XF/EQ models), 4 washers (SuperFlo/SuperMax series), or 6 washers (IntelliFlo/WhisperFlo series). Always verify your pump model and parts diagram before ordering. Compatibility data sourced from Pentair official parts documentation.

Pro Tip

Verify the part number stamped or printed on your existing washer before ordering. The product record contains a minor dimension discrepancy (7/8" vs. 13/16" outer diameter) that could not be resolved against a primary Pentair source. If your equipment manual or the original washer specifies a different outer diameter, verify with Pentair documentation before ordering.

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.
