Main Piston Assembly ( P.N. 60090 ) used in Fleck 1500, 2500, 2510, 2700.
This assembly comes complete with seal o-ring end plug PN 40078, old part number 10234, and quad o-ring ( 10209 ).
Matching Seal Kit is 60121.



NOTE:If the Valve is Leaking from the Front of the Main Piston, you Must Replace the Main Piston Assembly to stop this type of EXTERNAL Leak.

The Seals and Spacers need replacing when you have "internal" leaking of the Valve.
This would be constant flow out the drain line, or failure to create suction ( after injector and brine valve check out okay ), or hard water getting into the house when everything else appears to be working fine.

NOTE: Does NOT fit General Ionics valves.
