The Swimables Replacement for Pentair Backwash Valve Piston Assembly SW-26-130 with O-Ring is a compatible replacement for Pentair 51013811, designed for select Pentair push-pull and slide backwash valves. This complete piston assembly restores proper valve operation by controlling internal water routing during both filtration and backwash cycles.

The assembly includes the piston stem and handle-style operating shaft configuration for straightforward installation.
