WSP Whole House Iron & Sulfur Filter - All-In-One, Control Flow

If your water leaves orange-brown stains on sinks and toilets or your hot water smells like rotten eggs, this system helps reduce those iron and sulfur problems. It treats all the water entering your home to protect your fixtures and laundry.

The problem you’re dealing with

You see orange or brown rings around your toilet tank, rusty spots on your dishes, or discoloration on laundry that won’t wash out. Maybe your shower water smells like rotten eggs, especially when it’s hot. These are classic signs of iron and sulfur in your water. It’s not just unsightly — it’s a daily nuisance you clean around and live with.

Why it’s happening

This trouble comes from iron dissolved in your water and hydrogen sulfide gas, which smells like rotten eggs. Iron often makes water look rusty or leaves stains on plumbing fixtures. Sulfur can come from bacteria that feed on sulfur compounds underground, releasing that strong odor when water heats up. A simple iron test or a sulfur smell check—usually just smelling hot water—can confirm if these are your issues.

What it’s costing you to leave it

Leaving iron and sulfur untreated means more time scrubbing stains, more detergent to get clothes clean, and faster scale buildup in your water heater. Stains become harder to remove the longer they sit, and your appliances have to work harder, shortening their lifespan. Over time, these annoyances add up to more work and replacement costs you don’t need.

How this system fixes it

This filter works by drawing in air to oxidize iron and sulfur compounds—that’s a chemical reaction that changes dissolved iron and sulfur into particles you can filter out. It uses a meter to monitor your water use and backwashes to clean itself only when it needs to, so it runs efficiently. No salt or chlorine is added, which keeps running costs and maintenance low.

What this system can handle

This all-in-one filter is built to handle iron and sulfur problems throughout your whole house, treating all the water at a single point of entry. Its compact 10" x 44" tank fits in tight spaces but has the capacity to serve most family homes comfortably. Because it uses a metered control system, it adjusts to your water usage, making it water- and energy-efficient. The included bypass valve lets you isolate the system for service without shutting off water to your home.

What you actually get

The system includes a durable black polyglass tank covered by a lifetime warranty on the pressure vessel, so the main tank is protected for life. The control valve and electronics come with the manufacturer’s standard warranty. You also get a bypass valve included at no extra cost, which allows you or your plumber to isolate the system during maintenance. For drainage, the system comes with 10 feet of discharge hose ready to connect to your home’s drain.

Is this the right size for you?

This unit suits most homes with moderate iron and sulfur levels looking for a compact, efficient whole-house solution. Homes with very high iron or sulfur may need a larger or different system. If your water problems are mild or you only want treatment at a single faucet, a smaller unit might be better. Your plumber or the WSP team can help confirm the right fit based on your water test and household needs.

Living with it

Maintenance involves occasional backwashing, which the system manages automatically based on your water use. You’ll need periodic checks by your plumber to ensure everything runs smoothly. Because it doesn’t use salt, chlorine, or other chemicals, upkeep stays straightforward and costs are mainly for routine maintenance and occasional media replacement as recommended.

What it won’t do

This filter helps reduce iron and sulfur but does not soften hard water or remove other contaminants like sediment, bacteria, or heavy metals. If your water is hard, you’ll want a separate softener. For bacteria or other specific issues, different treatment systems are necessary.
