Up Flow Regeneration—Slow Rinse
Raw water is directed from the inlet through the nozzle and into the throat. A vacuum is created but the brine valve has
seated, so no brine is educted. The raw water enters the mineral tank, passes through the resin, up the manifold and to
the drain. Hard water is allowed to service during regeneration.
