During the vent step, the drain valve opens up and check stem unchecks
11. Brine
In the brine draw step, the check stem is opens, and brine is drawn by the
venturi into the resin bed. Brine flows down through the resin from the top
of the tank to the lower distributor and up the central distributor tube.
Then, the brine flows out the drain valve to the drain line.
12. Slow Rinse
During slow rinse, there is no change in the position of the internal valves in
the Solitaire valve. If the saturated brine in the cabinet or brine drum is
drawn down far enough, then the air check on the brine valve checks, and a
slow rinse of water begins. The slow rinse flows down through the resin and
lasts until backwash begins.
13. Backwash
The backwash step begins when the outlet valve opens up. Backwash is
downflow through the resin and rinses the excess brine out of the resin bed.
14. Stop Backwash
After backwash, the drain valve closes.
