IRON FILTER Rebuild Kit Fleck 5600 green sand application,
Our 56PSKITIRONFILTER includes
Main Piston Assembly 60102-10 ( for units that draw potassium permanganate or chlorine ),
Seals and Spacers 60125,
Brine Valve Piston 60032
Over time the wear and tear on the Pistons and Seals can cause the Valve to become STUCK in the regeneration cycle.
Replacing these 3 assemblies will usually restore the control valve to like new condition.
The Fleck Manual also recommends replacing the Injector Drain Module Orings listed below ( 3456IDMO ).
It is not normally necessary to replace the o-ring ( 13302 ) in the Brine Valve "hole".
Note there are 2 of these orings ( 13302 ), and one comes on the new Brine Valve Piston Assembly ( 60032 ).
If you want or feel you need this extra o-ring, please order it separately.
And other less common reasons that it might be "binding", or still getting stuck after replacing the Piston and Seals.
