COMPATIBILITY & APPLICATIONS
System Fitment
This piston is engineered specifically for Fleck 5600 control valves used in water softener and filter systems. It replaces worn or damaged pistons in existing valve bodies and is compatible with all 5600 valve configurations including mechanical and electronic timer models. Common applications include residential water softeners, iron filter systems, and commercial water conditioning equipment using Fleck 5600 valve platforms.
💧 Keep a spare 13852 piston on hand if you service multiple Fleck 5600 systems. Piston wear is one of the most common causes of valve cycling issues and reduced regeneration performance.
