WSP Whole House Iron & Sulfur Filter - Sentry Methane

Notice the orange-brown stains fading from your sinks and tubs within days, while that rotten-egg smell in your hot water starts to lessen. This is the result of consistently cleaner water, free from the iron and sulfur compounds that cause stains and odors.

What You’ve Been Putting Up With Every Day

Orange-brown rings in your toilet tank, rust-colored stains on your shower doors, and that unmistakable rotten-egg odor when you run hot water make daily chores less pleasant. Your laundry may look dull or grayish, and your coffee might taste off, almost like you’re using pool water. Scrubbing these stains feels like a never-ending task, and the smell can linger in your kitchen or bathroom, making your home less comfortable.

How the Control Head Keeps Things Running Smoothly

This system’s automatic control head manages cleaning cycles all on its own. It runs service, backwash, and rinse cycles as needed, so you don’t have to think about it. Designed to work with typical household water pressure, it keeps the filter bed fresh by flushing out trapped iron and sulfur regularly. You set it up once, and it handles the rest, saving you time and hassle.

The Media That Tackles Iron, Manganese, and Sulfur

Inside the tank, there’s a special oxidizing filter bed that works by turning iron, manganese, and hydrogen sulfide from dissolved forms in your water into particles. This process makes these troublesome minerals easier to remove during backwash cycles. The system also uses air in the process, which helps to safely vent methane and similar gases found in some well water sources. This combination is effective at reducing the staining and smell that come with these elements.

A Tank Made to Handle Your Whole House Supply

The tank holds 22 gallons and includes a bladder to keep water pressure stable between pump cycles. This size is built to serve a typical single-family home’s entire water supply, so you don’t see pressure drops when multiple taps run at once. The 2-inch porting supports steady flow and efficient venting for gases removed from the water, ensuring consistent performance.

Is This Filter the Right Choice for Your Home?

This system suits most single-family homes on a whole-house water supply, especially those with well water affected by iron, manganese, sulfur compounds, or methane gas. It works well if your home runs on a typical 40/60 pressure system and you want reliable, automatic treatment. If you have a larger household or unusually high water demands, you may want to consider a larger-capacity system to keep up with peak flows. Conversely, smaller homes or lower flow needs might benefit from a simpler, smaller unit.

What You’re Getting and What Happens Next

The system ships with a lifetime warranty on the tank, covering the pressure vessel itself for life. The control valve and electronics come with the manufacturer’s standard warranty terms. Included in your purchase is a bypass valve, which lets you isolate the system while keeping water flowing to your home during maintenance, something many competitors charge extra for. You’ll also get 10 feet of discharge hose for the drain line, all shipped from Tampa with free U.S. delivery. Once you order, our team will confirm the best configuration for your water, and you can arrange installation with your local licensed plumber.

Who this size is right for

What you are buying here is a whole-house system, plumbed into the main line so every tap in the house is treated. On a typical 1-inch service line that means a single-family home.

There is no published capacity figure for this item, so we size it from your water rather than from a table. Send your peak flow rate and a water test and we will confirm what you need - it costs nothing and it avoids buying twice.
