Including filter system and high-performance Tannins filter.
Tannins are natural organic compounds that can give water a yellow, amber or tea-like tint. In areas like Frink they often appear when groundwater flows through decaying plant material or certain soils, and while they may not always be obvious from taste alone, they can produce an earthy or musty flavor. Over time tannins can leave stubborn stains on plumbing fixtures, appliances and laundry, and make drinking water look less appealing.
Because tannins dissolve in water, they won’t settle out like sand and can pass through basic cartridge filters. Frink homeowners often spot the issue when clear glasses take on a tint, white clothing develops a yellow cast, or soap doesn’t rinse away well. Tannins can also interact with iron to make discoloration more obvious and trickier to identify. The best way to know if tannins are present is a water test, then select treatment that matches the results.
For whole-house tannin control, the most effective single-filter choice is an anion exchange system made for tannins. That system uses a specialized resin that attracts negatively charged organic molecules and removes the dissolved, tea-colored compounds before water reaches your taps. Compared with standard carbon filters, anion exchange is generally better at eliminating the color and tint tannins cause; installed at the main water line, it protects plumbing, fixtures and everyday water use in Frink homes.
An anion exchange tannin filter performs best when paired with appropriate prefiltration and correctly sized for your household so it won’t clog or channel. Like a water softener, the resin requires periodic regeneration to flush captured organics and restore capacity. If your water has iron, sulfur odors or sediment in addition to tannins, treating those issues together will help stop staining from returning and improve clarity.
