The add on brass bypass kit helps control the water flow through the deionizer. The ball valves allow you to bypass the deionizer when it is not needed, which helps to prolong the life of the resin. The kit connects by switching out the existing inlet and outlet with the new included brass adapters. The kit includes all the necessary equipment to bypass the deionizer when needed, and ultimately extend the life of your deionizer.
