WSP Whole House Tannin Filter

If your tap water runs yellow or looks like tea, that’s tannins in your source water staining everything it touches. The WSP Whole House Tannin Filter from Water Softener Plus is designed to help reduce that discoloration, making your water clearer throughout your home.

The Problem

Your water might come out of the faucet with a yellow or brown tint, like brewed tea. This discoloration stains toilets, sinks, and shower doors, and leaves a film that’s tough to wipe away. Laundry can look dull and towels may feel rough. Even your coffee might taste off. This is more than an eyesore — it’s a daily nuisance that affects everything water touches in your home.

Why It’s Happening

The color comes from tannins, natural organic compounds washed into your water from soil and decaying vegetation. Tannins don’t settle out and aren’t removed by regular water softeners. The simplest way to confirm their presence is a water test that shows organic color or tannin levels above zero. If your water’s yellow or tea-colored, tannins are the likely cause.

What It’s Costing You to Leave It

Leaving tannins untreated means you’re constantly battling stains and sticky films. Cleaning requires more time and stronger detergents, and your appliances have to work harder to get clothes and dishes truly clean. Over time, these deposits can build up, making stains harder to remove and potentially shortening the life of water-using equipment. It’s an ongoing hassle and expense that doesn’t go away on its own.

How This System Fixes It

This system uses a process called ion exchange, where special resin inside the tank attracts and holds the tannin molecules from your water. As water flows through, the resin captures the color-causing organics, and the system periodically cleans the resin by flushing it with salt brine. This keeps the filter ready to keep reducing tannins day after day.

What This System Can Handle

The WSP Whole House Tannin Filter tackles the full range of tannin problems, helping reduce yellow or tea-colored water throughout your home — at every tap and appliance. It’s sized to match homes with 1 to 6 bathrooms, handling typical household water volumes and tannin levels. The system’s control valve meters your actual water use and triggers regeneration only when needed, so it doesn’t waste salt or water between cycles. It stands up to steady daily use, and the media inside can be serviced or replaced as needed, rather than being a sealed, disposable cartridge.

What You Actually Get

You receive the complete working system ready to install by your plumber. This includes the specialty ion-exchange tank filled with Purolite tannin-selective resin, a Fleck 5810 SXT metered control valve to manage the process, and 10 feet of discharge hose for the drain line. A bypass valve is included so you can isolate the system during maintenance without interrupting your water supply. The tank itself carries a lifetime warranty, ensuring the pressure vessel is covered for life. The control valve and electronics have their own manufacturer warranties.

Is This the Right Size for You?

This system fits homes with between 1 and 6 bathrooms, covering small to larger households. If you have fewer than 1 bathroom or extremely low water usage, a smaller unit may be more efficient. For homes larger than 6 bathrooms or with unusually high tannin levels, sizing up or a custom solution might be necessary. We provide guidance to make sure the system matches your home’s water volume and tannin load correctly.

Living With It

Maintenance involves adding salt periodically for regeneration and occasional service to the control valve and resin media. The system’s metered control valve means it regenerates only when your water use calls for it, keeping salt and water usage to a minimum. Your plumber can handle any servicing or media replacement if needed. The included bypass valve makes servicing straightforward without shutting off your water.

What It Won’t Do

This filter is designed specifically for tannins and the color they cause. It does not reduce hardness minerals that cause scale, nor does it remove iron, sulfur, bacteria, or sediment. If you have those issues, they require separate treatment systems designed for hardness, iron, or other contaminants.
