Hard water enters at valve inlet and flows down thru mineral to
the bottom distributor. Conditioned water flows up thru the dis-
tributor tube, around the piston and out the outlet.

Inlet
Hard water enters at valve inlet – flows thru service adapter piston
for by-pass, and up thru coupling to regeneration valve inlet. Flow
continues thru the regeneration valve piston – down the distribu-
tor tube – thru the bottom distributor and up thru the mineral –
around the piston and out the drain. If optional no hard water by-
pass piston is used, water flow to service outlet is prevented by
an extension on the service outlet until the end of the rapid rinse
cycle or brine tank refill cycle, depending on options chosen.
