The fast rinse is basically an extension of the slow rinse in the previous page. The control valve has moved sufficiently far to allow the small brine valve piston to spring back into place. This ensures that the brine system has been totally isolated from the fast rinse operation, and no water can find it's way under pressure into the salt tank. The main operating piston has moved in an upward direction to allow a greater volume of water to enter the resin vessel thereby purgeing the resin of any remaining salt water. This sequence lasts approximately six minutes and leaves the resin clean, fresh and ready to soften more water.
There is only one more operation left to complete the REGENERATION, and that's to fill the salt tank with sufficient water, to dissolve the correct amount of salt, to produce the correct amount of brine, for the next regeneration.
This operation , strangely as it may seem is called BRINE TANK REFILL, and is the last part of the cycle to be explained.
