Yellow, tea-colored tannin water doesn't just stain your fixtures — it seeps into every faucet, turning your daily water use into a frustrating ritual. The telltale amber tint can leave laundry dingy, discolor your glassware, and stain sinks and tubs, silently eroding your home's value. Ignoring these symptoms means perpetuating the damage: brittle plumbing and compromised water quality that affects your family's comfort and health.

The system that fixes it

The C-Series Yellow, Tea-Colored Tannin Water System is engineered precisely to tackle the stubborn organic tannins responsible for that unwelcome amber hue. At the heart of this solution is the C-Series metered control valve, a genuine brand valve designed for precision and durability. This control valve intelligently tracks your water usage, initiating regeneration only when necessary to maximize efficiency and extend system life. The system is built on a specialty ion-exchange tank, filled with Purolite tannin-selective anion resin — a unique media engineered to adsorb the organic tannins that create that tea-colored tint. Periodic brine regeneration flushes the resin, keeping your system performing at peak capacity without wasting salt or water. This isn’t just a filter; it’s a comprehensive, serviceable system that protects your home and restores clean, clear water.

How the media works

The secret weapon in this system is the Purolite tannin-selective anion resin, a specially formulated media that targets the organic tannins responsible for the yellow discoloration. This resin operates through ion-exchange and adsorption: tannin molecules in the water are drawn out and held tightly within the resin beads, essentially trapping the tea-colored compounds before they reach your faucets. Over time, the resin saturates and needs renewal, which is accomplished through an automatic brine regeneration process. Saltwater flushes the system, releasing the trapped tannins and refreshing the resin so it can continue its work without interruption. This cycle ensures consistently clear water and a dependable shield against tannin staining.
