Up Flow Regeneration—Brine Draw
Raw water is directed from the inlet through the nozzle and into the throat. A vacuum is created and concentrated brine
is educted (drawn). The raw water and concentrated brine combine, enter the mineral tank, and pass through the resin,
up the manifold and to the drain. Once all of the brine has been educted and the brine valve seats, the unit goes into slow
rinse. Hard water is allowed to service during regeneration.
