Our dual-tank filter addresses problems associated with acidic water (blue-green stains on copper fixtures or pipes, or in tubs and sinks) by using calcite to raise the pH of your water to a neutral level of 7.
Calcite Backwashing Filter Highlights
Fresh, Clean Water
Twin tanks accommodate higher flow rates needed in multi-person and larger homes, while the Kinetico non-electric control valve provides on-demand backwashing.
Moving water is the power source, not electricity, so operation is simple and reliable. There are no timers or computers to set, adjust, repair or replace.
Systems meter water use and backwash based on actual usage. You won't waste water on unnecessary backwashing.
