Lower Piston Assembly, 2900 (FL61550) new number
Product Description
Lower Piston Assembly used on the Fleck 2900 and 2930 valves. This is the HWBP version, which permits Hard Water to Bypass the valve, during a regeneration cycle. Some applications require the NHWBP (No Hard Water Bypass Piston), that will stop all water flow from getting past the control vavle, during the regeneration cycle. This Part can be located on page 16, of the Fleck 2900 Service Manual. Free Fleck Service Manuals, can be located on the Index, on the Left Side of our website. (Old part # FL60103)
