WSP Whole House Tannin Filter

WSP Whole House Tannin Filter tackles yellow, tea-colored water caused by tannins that stain your laundry and dull your clothes. It helps reduce these stains and discolorations throughout your entire home supply, restoring the look and feel of your fabrics.

Why Your Laundry Loses Its Color and Feels Rough

Have you noticed your clothes coming out of the wash with a yellowish tint or looking faded faster than usual? That dullness and discoloration often come from tannins in your water, natural organic compounds that give water a tea-like color. Over time, these tannins leave yellow stains on your whites and light-colored fabrics. Towels might feel less soft and vibrant, and your favorite shirts start to lose their brightness. It's not just about looks; it’s about your clothes aging prematurely in every load you wash.

How the Control Head Manages Water Treatment Efficiently

The system features a metered control head that tracks your actual water use. This means it only regenerates—the process that refreshes the filtering media—when necessary. You set a few basic preferences, and the control valve handles the rest automatically. This approach avoids wasting salt and water on unnecessary cycles, saving you money and minimizing maintenance. The control valve is built to be serviceable, not a sealed unit, so parts remain available if needed down the road.

The Media Inside: Why It Works on Yellow Tannin Water

Inside the tank, a blend of specially selected resin handles your water’s challenges. The high-capacity cation exchange resin targets hardness, while the anion exchange resin focuses on tannins and dissolved organic compounds—the substances responsible for the yellow tint. The tannin-selective anion resin’s job is to help capture those tea-colored materials effectively. Together, this combination reduces the yellow staining and improves the clarity of water flowing through your home.

The Tank’s Role and What It Means for Your Home

The tannin filter comes with a sturdy pressure vessel designed to hold the ion exchange media. While the exact tank size is determined based on your home’s water use and tannin levels, it is built to handle whole-house treatment needs. This means all the water coming into your home is treated before it reaches your faucets and appliances, offering consistent quality throughout.

Which Homes Are Best Suited to This Filter

This system is designed for a typical single-family home’s entire water supply. It suits homes with tannin-stained water that affects laundry and general water appearance. If you have multiple bathrooms or a higher water demand, we recommend confirming your flow rate and water test results to ensure the sizing fits your needs. Conversely, smaller homes or those with minimal tannin presence might consider a smaller unit or alternative treatment.

What You Get When You Order This System

You receive the complete tannin filter system ready to install by your licensed plumber. The package includes the metered control valve, the pressure tank filled with the right media, a bypass valve so you can isolate the system during service without cutting off your home's water, and 10 feet of discharge hose for the drain line. The tank comes with a lifetime warranty, while the control valve and electronics carry the manufacturer's standard warranties. U.S. shipping is free and included in the price.
