Fast rinse cation cycle.
The rinse is complete when the pH of the water exiting to drain is between 2.5 and 3.0 and the Hardness is 0 grains.
Samples can be taken at the test cock just below the Rinse Outlet Valve. This test cock can also be used to tell when the
acid breaks through the bottom of the resin bed. When Rinse is complete, the Cation Column returns to the Service Cycle.
Water flows into the Cation Column and out the bottom over to the Anion Column. The Anion regeneration will start the
Backwash Cycle.
