61630-00 – Fleck 2850s Piston Assembly – HWBP

Fleck 61630-00 Piston Assembly

Fits only the 2850s model valve (note the “s” in the model number)

Does NOT fit the standard, older 2850 valve.

HWBP = HARD WATER BYPASS – During the regeneration cycle the system the unit will bypass itself and service water will be hard.
