Two eductor / four-way selector valve assembly

Abstract

A method of controlling the flow of different flow paths of fluid is provided. The method includes rotating a valve to a first position, receiving a first concentrate in the first position, discharging the first concentrate through one of two outlets, rotating the valve to a second position, receiving a second concentrate in the second position, and discharging the second concentrate through one of the two outlets.

1 . A method of controlling the flow of different flow paths of fluid through a selector valve assembly, the method comprising:
 rotating a control member to a first position;   receiving a first concentrate in the first position;   discharging the first concentrate toward one of two outlet passages;   rotating the control member to a second position;   receiving a second concentrate in the second position; and   discharging the second concentrate toward one of the two outlet passages without adjusting a position of the outlet passages.   
     
     
         2 . The method of  claim 1 , wherein the control member includes a valve, the method further comprising, after the step of receiving a first concentrate in the first position, directing the first concentrate through a passageway in the valve. 
     
     
         3 . The method of  claim 2 , further comprising rotating the valve via a knob. 
     
     
         4 . The method of  claim 2 , further comprising, after the step of receiving the second concentrate in the second position, directing the second concentrate through the passageway. 
     
     
         5 . The method of  claim 1 , wherein the step of receiving the first concentrate in the first position further includes receiving the first concentrate in the first position from a first port. 
     
     
         6 . The method of  claim 5 , wherein the step of receiving the second concentrate in the second position further includes receiving the second concentrate in the second position from a second port. 
     
     
         7 . The method of  claim 1 , wherein the step of discharging the first concentrate toward one of the two outlet passages further includes directing the first concentrate to a first eductor or a second eductor.
