When your water pours out with an unmistakable yellow or tea-colored tint, it’s not just an eyesore—it’s a hidden hazard silently staining your fixtures, dulling your laundry, and leaving behind unpleasant tastes and odors. This organic tannin discoloration can turn your taps into a source of frustration, causing premature wear on appliances and making even simple tasks like washing dishes or bathing feel unclean and uncomfortable. Without the right solution, yellow tannin water undermines your home's value and your family’s comfort every day.

The system that fixes it

Say goodbye to unsightly yellow, tea-colored water with the Pentair Yellow, Tea-Colored Tannin Water System—engineered specifically to tackle organic tannins that stain and discolor your water supply. At the heart of this system lies the Pentair-series metered control valve, a precision-engineered head valve that measures your water usage to optimize regeneration cycles. This intelligent valve ensures the system performs efficiently, extending media life and conserving salt and water—key to long-lasting performance and lower operating costs. The system’s backbone is a specialty ion-exchange tank custom-built to house the Purolite tannin-selective anion resin media, which aggressively adsorbs and removes tannins before they reach your taps. Regenerating with brine, the media is refreshed to maintain peak tannin removal over time, protecting your home from the unique challenges of tea-colored water.

How the media works

The secret weapon in the Pentair system is the Purolite tannin-selective anion resin. This advanced resin functions by seeking out and binding to the organic tannins dissolved in your water—the molecules responsible for that stubborn yellow tea color. Through ion-exchange, the resin captures these tannins, effectively removing them before the water flows to your faucets. Over time, as the media collects tannins, it regenerates by flushing with a brine solution, which cleanses the resin beads and restores their tannin-adsorbing capacity. This cycle ensures continuous performance, so your water stays clear and free of discoloration without frequent media replacement.
