How is the carbon changed out?
It is a simple process that takes no more than 30-60 minutes every 7-10 years! The system is put on bypass by turning off the water to the system. Relieve the pressure in the tank by cycling the valve into a backwash. Remaining water will expel, and then air as pressure is relieved. Disconnect the backwash/drain line and unplug the system. Disconnect the valve head from the bypass, allowing the tank to pull away from the pipes. Unscrew the valve head and lift off. The carbon and water in the tank can either be dumped out, hosed out with water, or a wet/dry vacuum can be used to suck out the water and wet carbon. Once the water, carbon and ICN riser manifold are removed, a complete kit that contains the new ICN riser manifold and the correct amount of GAC media is inserted making this an easy process. The carbon will fill 2/3 of the tank, which allows 1/3 of freeboard area, which is necessary for backwashing purposes. Once media is replaced, pre-fill the tank with water, then screw on t
