Push-pull backwash valves rely on the piston assembly to shift water flow between filtration and backwash paths. This replacement piston assembly is designed for compatible PacFab 2-inch slide and 1-1/2-inch backwash valve applications, helping restore movement when the original part is worn or leaking.
- Replacement piston assembly for select PacFab backwash valves
- Supports filter and backwash flow control
- Useful when the slide action becomes stiff, damaged, or unreliable
- Helps renew internal valve function without full valve replacement
- Verify valve size and configuration before ordering
