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

When a water test shows dissolved iron and hydrogen sulfide, you might wonder what those numbers mean day to day. Orange-brown stains on fixtures and laundry, along with a rotten-egg smell in hot water, are the clear signs you’re dealing with these common water issues.

Recognizing What Your Water Is Telling You

Rust-colored rings in your toilet tank, orange stains on sinks and tubs, or that sour sulfur smell when you run hot water are all signals of dissolved iron and sulfur compounds in your water. These aren’t just cosmetic annoyances. The metallic taste in coffee or water and laundry that looks dingy despite repeated washing can also be linked to these elements. You’re spending time scrubbing, and your appliances could be taking a beating, but the root cause isn’t always obvious until you test the water.

How the Control Head Keeps Your System Working Smoothly

On top of the tank is an automatic control valve that manages the system’s cleaning cycles. It uses an air-draw feature, pulling in a pocket of air without any added chemicals. This air reacts with the iron and sulfur in your water, turning them into particles that the media can catch. The control head’s 1.5-inch porting supports steady flow, making sure your water treatment keeps pace with your household needs. It backwashes the media on a schedule you can program, so it stays clean and effective without wasting water or salt.

What’s Inside the Tank Does the Heavy Lifting

The heart of this system is the catalytic manganese-dioxide media inside the pressure vessel. This media encourages oxidation—the process that transforms invisible dissolved iron and hydrogen sulfide into solid particles. Because it targets iron, manganese, and smelly sulfur compounds, it’s well-suited for homes struggling with staining and odors. The air pocket that the control head maintains enhances this process without chemicals or replacement cartridges.

The Tank and What Its Capacity Means for You

The exact size of the pressure vessel depends on your water needs and will be confirmed when your system is sized. It’s designed to handle flow rates up to 10 gallons per minute, which is typical for an average family home. That means it can keep up with everyday use without slowing down, treating water as it enters your home before it reaches your taps and appliances.

Is This System the Right Fit for Your Household?

This iron and sulfur filter suits a family of three to four people, with two or three bathrooms. It fits homes where staining and sulfur odors are recurring problems but flow demands are moderate. If you have a larger household, higher flow requirements, or more severe water issues, a larger or different system might be necessary. We’ll help you find the right size based on your water test results and household plumbing.

What Comes With the WSP Whole House Iron & Sulfur Filter

The system includes a lifetime warranty on the pressure vessel, so the tank itself is covered for as long as you own your home. The control valve and electronics come with the manufacturer’s standard warranty. A bypass valve is included at no extra cost, allowing you to isolate the system for maintenance without shutting off water to the house. We also provide 10 feet of discharge hose for the drain line, making installation straightforward for your licensed plumber.

Who this size is right for

This is rated for roughly 10 gallons per minute of service flow, which suits an average family home - around 3-4 people with 2-3 bathrooms.

Flow rate matters more than tank size here: add up the fixtures that could realistically run at the same time and make sure this covers them. If you land close to the limit, go up rather than down.
