WSP Whole House 1,4-Dioxane Reduction System

If your water contains 1,4-dioxane, a stubborn industrial solvent stabilizer that regular filters don’t catch, this system from Water Softener Plus (WSP) is designed to help reduce it. It’s built for the tough job of treating water with this trace contaminant.

The problem

You may not notice 1,4-dioxane in your water because it has no smell or taste, but it’s there if testing shows it. Ordinary filters and softeners don’t reduce it, so your water could still carry this chemical even if you have treatment equipment. It’s a problem because 1,4-dioxane resists the usual filtration methods and stays in your water unnoticed.

Why it’s happening

1,4-dioxane is a synthetic chemical used in industry as a stabilizer in solvents. It can seep into groundwater and then into your water supply. Because it doesn’t bind well to typical filter media like carbon, it passes through most standard filtering setups. The only way to be sure it’s affecting your water is through specialized lab testing designed to detect this chemical specifically, since it’s not found on standard water tests.

What it’s costing you to leave it

Leaving 1,4-dioxane in your water means your treatment system isn’t fully addressing all contaminants. While it doesn’t cause visible stains or smells, it limits the effectiveness of your water treatment and leaves you with water quality that isn’t as clean as it could be. Over time, this means you’re still living with an industrial chemical in your water supply, even if other issues like scale or sediment are under control.

How this system fixes it

This system uses specialized media designed to capture or break down 1,4-dioxane where ordinary filters fail. It relies on a process called adsorption, where contaminants stick to a specially formulated material, and in some cases uses advanced oxidation to break down the stubborn molecules. Because 1,4-dioxane is present at very low levels and is hard to catch, the system is sized precisely to your water’s test results to ensure enough contact time for reduction.

What this system can handle

The WSP Whole House 1,4-Dioxane Reduction System is built specifically for the challenge of reducing 1,4-dioxane and other hard-to-treat trace contaminants. It can treat the full volume of water entering your home, so all your taps benefit from this treatment. The system is designed to work continuously until it needs regeneration or maintenance, handling typical household water volumes without losing effectiveness. It’s a step up from standard carbon filters because it targets compounds that don’t respond to those alone.

What you actually get

The system comes with a pressure vessel that carries a lifetime warranty from Water Softener Plus. It includes a bypass valve at no extra cost, so your plumber can isolate the system for service without shutting off your water supply. You also receive 10 feet of discharge hose to connect the system to your drain line. The control valve and electronics are covered by the manufacturer’s own warranty terms, which are detailed in the manual you’ll receive.

Is this the right size for you

This system suits households with confirmed 1,4-dioxane contamination where lab results guide the sizing to your water usage and contaminant levels. If your water tests show very low or no 1,4-dioxane, a simpler system may be enough. Conversely, if your water has higher flow demands or other challenging contaminants, you might need to discuss a larger or additional treatment. We help you find the right fit based on your specific water test.

Living with it

Maintenance involves periodic regeneration or replacement of the specialized media, depending on your water use and contaminant levels. The bypass valve makes servicing easy without interrupting your water supply. The system’s running cost includes only routine upkeep and occasional media replacement as advised after sizing. There’s no need for complicated upkeep beyond what your plumber will manage during regular service visits.

What it won’t do

This system is focused on reducing 1,4-dioxane and similar trace organic compounds. It does not soften water or remove minerals that cause scale, nor does it address bacteria, viruses, or heavy metals. For those issues, you would need separate or additional treatment systems tailored to those specific problems.
