Sterling Water Treatment Fleck 2510 Repair Bundle is an all-in-one rebuild solution designed to restore internal pressure seals and stop active water waste. This maintenance kit includes the Main Piston Assembly (STW60090) and the Main Piston Seal & Spacer Kit (STW360060121) to completely overhaul your Fleck valve’s internals.

-
Hard Water Leakage: Prevents untreated, hard water from slipping past worn seals and entering your home’s clean water supply.
-
Poor Regeneration: Restores the vital internal suction required for a proper brine draw and efficient system cycling.
