WSP Whole House Iron & Sulfur Filter - Well Water, Rust Hardness

If your well water leaves orange-brown stains on fixtures or toilets, or the hot water smells like rotten eggs, this system helps reduce iron and sulfur issues throughout your home. It’s designed for whole-house use and handles both staining and odor problems together.

The problem

Orange or rusty stains on sinks, tubs, and toilets can be stubborn and frustrating. You might notice a slimy film or scale building up on shower doors and faucets. At the same time, there may be a distinct rotten-egg smell in your hot water that won’t go away, especially when you run the shower or fill a pot. Towels and clothes washed in this water might come out dingy or stiff. This combination of staining and odor usually comes from iron and sulfur compounds dissolved in your well water.

Why it’s happening

Iron in water shows up as orange-brown rust stains after it reacts with oxygen and settles out. Sulfur, often from hydrogen sulfide gas, causes that rotten-egg smell when it’s released from the water, especially with heat or aeration. A simple iron and sulfur water test can confirm if your water has these elements in high amounts. This test measures dissolved iron and the presence of sulfur compounds causing the smell.

What it’s costing you to leave it

Iron deposits can build up inside your water heater, plumbing, and appliances, reducing their efficiency and shortening their life. The staining on fixtures takes regular scrubbing and strong cleaners to remove, often leaving behind stubborn rings and marks. The sulfur smell makes simple tasks like showering or cooking less pleasant. Laundry may look dingy or get stiff, requiring more detergent and repeated washing to feel clean. Over time, these issues mean more work, expense, and wear on your home’s water-using systems.

How this system fixes it

This is a two-stage system designed to work together. First, it uses air injection to add oxygen to the water, which changes dissolved iron and sulfur compounds into solid particles. These particles are then filtered out in the same stage. After that, the water moves through a second stage that softens it by exchanging hardness minerals—calcium and magnesium—for sodium. This combination helps reduce staining, odor, and scaling problems in your whole house.

What this system can handle

This system treats both iron and sulfur problems effectively, as well as water hardness that causes scale. It’s built for well water with moderate to higher levels of these issues. The two-stage setup means the iron and sulfur filter protects the softener from fouling, keeping maintenance lower. You can choose from sizes fit for homes with 1 to over 6 bathrooms, ensuring enough capacity for your household’s daily water use. The system automatically backwashes and regenerates, handling water use efficiently and reliably before it needs servicing again.

What you actually get

The system includes a pressure vessel (the tank) covered by a lifetime warranty, giving long-term protection for this key part. You also get a bypass valve included, so your plumber can isolate the system during any maintenance without stopping water flow to your home—something many competitors charge extra for. To connect to your drain for backwashing, 10 feet of discharge hose is supplied. The control valves and electronics come with the manufacturer’s standard warranty. Exact system details are confirmed when sized to your water test.

Is this the right size for you?

This setup suits homes with well water that has noticeable iron staining and sulfur odors, and typical water hardness. If your household has fewer than three bathrooms or very low iron and sulfur, a smaller system might be more appropriate. For larger homes or higher water usage, sized options are available to match your needs without overspending or underserving. Getting a water test before ordering helps confirm the best fit.

Living with it

Maintenance involves periodic backwashing and regeneration cycles that the system manages automatically. Depending on your water use and iron content, you’ll need to refill softener salt and check the system occasionally, but these tasks are straightforward. The bypass valve makes it easy for a plumber to service the system without interrupting your water. While the iron filter media has a long life, some parts like control valves might need replacement down the line, but all parts are serviceable and available.

What it won’t do

This system helps reduce iron, sulfur odors, and hardness but does not remove other contaminants like bacteria, nitrates, or pesticides. If your water test shows those issues, you would need additional or different treatment tailored to those specific problems. This product is not designed for municipal water treatment or removing chlorination byproducts.
