Control Head - 5 year Tank - 10 year DIY Installation Instructions Eliminate the hard water that causes scale build up and iron that causes red staining with a single system! Eliminates Scale Buildup - Hard water causes a white flaky build up (called scale) to form on appliances, faucets, and just about anything that it comes in regular contact with. By removing the hard water, this scale build up is stopped in its tracks, so you don't have to worry about scrubbing it off any more. In addition, without the added wear and tear of scale buildup, your appliances and fixtures will last longer! Removes Ferrous Iron - this system is able to remove ferrous (clear water) iron, if you have ferric (red water) iron a dedicated iron filter is recommended. Removes Manganese - Manganese is commonly seen as a black "slimy" stain or build up. Meter Based Regeneration - This system uses a meter based regeneration process. This means that the water you use is measured and the system only regenerates when needed. If water needs increase the system regenerates more often to keep up. If less water is being used, the system regenerates less often to conserve water. Fleck 5600SXT Digital Control - The SXT controller is the newest controller from Fleck and is built on the tried and true 5600 valve.
