Fleck 2510 Combo Kit

The Fleck 2510 Combo Kit is a curated repair bundle from Water Softener Plus that packages the three most replaced wear items on a Fleck 2510 control valve into a single, money-saving set. Rather than tracking down individual parts and risking ordering the wrong one, you get the core drive and sealing components needed to refresh a tired 2510 in one go, matched and ready to install.

What's in the kit

• FL18743-1 — Timer/drive motor, 120V/60 Hz with brass gear
• FL60090 — Piston for 1500, 2500, 2510 and 2750 valves
• FL60121 — Seal kit for 1500, 2500, 2510 and 2750 valves
• Genuine Fleck components packaged for the 2510 platform
• Combines drive, piston, and seals for a complete hydraulic refresh
• Saves money versus buying each part separately

The 2510 is one of Fleck's most enduring control valves, common on residential and light-commercial softeners and backwashing filters and respected for its long service life. Over time, though, the piston and seals wear, allowing internal leakage and weak regeneration, while the drive motor's brass gear can strain or stall under the load of advancing the cam. Replacing all three together restores the valve's hydraulics and timing in a single service visit and avoids the frustration of repeat teardowns when a second part fails shortly after the first.

This combo is ideal for a homeowner or installer performing preventive maintenance or chasing symptoms like poor softening, salty water after a cycle, or a valve that won't advance. Tackling the work in order keeps it manageable: replace the piston and seals first, then fit the drive motor, and apply a light film of silicone lubricant to the new seals during reassembly so they slide in cleanly and seat well.

Before you begin, place the valve in bypass, relieve system pressure, and disconnect power. With these three high-wear parts renewed at once, your Fleck 2510 should return to smooth, dependable cycling, and you will have refreshed the components most likely to fail next, extending the valve's already impressive longevity. Keeping the valve high-wear parts fresh in this way is the single most effective maintenance step you can take to preserve the long, dependable service life the 2510 has earned over decades of use.
