WSP Whole House Iron & Sulfur Filter - Rust Stains

If your water leaves orange-brown stains on sinks and toilets or carries a rotten-egg smell when you turn on the tap, this system is designed to help reduce those iron and sulfur problems throughout your whole house. It’s built to handle rusty water and unpleasant odors that come from iron and sulfur in your water supply.

The problem you’re facing

Maybe you’ve noticed rusty orange rings inside your toilet tank or brown streaks on your bathroom fixtures that never quite come clean. Your shower doors have a filmy buildup, and laundry looks dingy or stiff no matter how much detergent you use. When you run hot water, there’s a lingering smell like rotten eggs. These are common signs of iron and hydrogen sulfide in your water.

Why it’s happening

Iron in water often comes from groundwater sources or old pipes. When iron is exposed to air, it turns rust-colored and leaves stains. Hydrogen sulfide gas creates that sulfur smell and can come from natural underground bacteria or decaying organic matter. The one simple way to check is a water test for iron and sulfur levels, which confirms if these are causing your stains and odors.

What it’s costing you to leave it

Iron stains build up over time, making cleaning a regular chore. They can damage plumbing fixtures and appliances by causing scale and corrosion underneath the visible rust. The sulfur smell makes hot showers unpleasant and can affect how your coffee or ice tastes. Laundry and dishes don’t come out as clean, so you use more soap and spend more time scrubbing.

How this system fixes it

This filter uses a process called oxidation inside a special tank. Air is mixed with the water to turn dissolved iron and sulfur into solid particles. Then the filter media traps those particles and flushes them out during a scheduled cleaning cycle, so the water coming into your home is clearer and fresher smelling.

What this system can handle

It’s designed to help reduce orange iron staining and the rotten-egg sulfur smell for whole-house use, whether your home has one bathroom or up to six. The system works automatically to backwash and clean itself, handling typical household water flow rates without needing constant attention. It’s suited to moderate iron and sulfur levels that cause visible stains and odors, making it a reliable choice if your water isn’t severely contaminated.

What you actually get

The system includes a durable air-injection oxidizing tank with a lifetime warranty on the pressure vessel itself, so that part is covered for the long haul. On top is the control valve that manages the air injection and backwash cycles, backed by its manufacturer’s warranty. A bypass valve comes standard, letting you isolate the system during maintenance without shutting off water to your whole house. For drain connection, 10 feet of discharge hose is included.

Is this the right size for you

This filter fits homes with between one and six bathrooms, grouped into three size options depending on your household’s water use. If your water test shows very high iron or sulfur levels, or if your home has more than six bathrooms, you may need a larger or more specialized system. For a smaller home or less severe staining, a smaller unit might be a better fit.

Living with it

The system runs mostly on its own. Every few days or weeks, it backwashes automatically to clear trapped particles to drain. You’ll want your plumber to check it annually or if you notice reduced water flow, to keep it working efficiently. The bypass valve makes service easier without shutting off water to your home. Aside from water and occasional inspections, it doesn’t add complicated upkeep.

What it won’t do

This filter helps reduce iron and sulfur but doesn’t soften your water or remove other contaminants like manganese, sediment, or chlorine. If your water contains these, you’ll need additional treatment tailored for those issues. It also won’t treat bacteria or viruses in water.
