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. Common Issues This Kit Fixes: Continuous Water Waste: Stops water from constantly trickling down the drain line 24/7 during the standard service cycle. 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. System Compatibility: STW360060121 Seal & Spacer Kit: Fits the main piston on Fleck 1500, 2500, 2510, 2700, and 2750 valves, as well as the upper piston on Fleck 2900 valves. STW60090 Main Piston Assembly: Fits Fleck 1500, 2500, 2510, and 2700 control valves. By refreshing the critical wear components inside the valve body, this heavy-duty bundle allows homeowners and technicians to easily avoid the high cost of a brand-new control head replacement.
