The WSP Whole House Iron \u0026amp; Sulfur Filter reduces these issues for cleaner water throughout your home.\u003c\/p\u003e\n\n\u003ch3\u003eThe Problem\u003c\/h3\u003e\n\u003cp\u003eOrange-brown rings on your toilet tank, rusty stains on sinks and tubs, and a persistent rotten-egg smell when you run hot water are clear signs of iron and sulfur problems in your water. These issues don’t just look or smell bad—they can affect how your water feels and the way your clothes and dishes come out.\u003c\/p\u003e\n\n\u003ch3\u003eWhy It’s Happening\u003c\/h3\u003e\n\u003cp\u003eIron and sulfur naturally occur in many water sources, especially well water. Iron shows up as dissolved particles that turn rusty when exposed to air, causing that orange staining. Sulfur, often in the form of hydrogen sulfide gas, creates the rotten-egg odor when it escapes from your water, especially when heated.\u003c\/p\u003e\n\u003cp\u003eA simple water test looking for iron and hydrogen sulfide concentrations can confirm if these are your problems. Many local labs or your plumber can perform such a test.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Costing You to Leave It\u003c\/h3\u003e\n\u003cp\u003eLeaving iron and sulfur untreated means you’ll keep scrubbing orange stains, wasting time and cleaners. The smell can linger in your water heater and pipes, affecting how your water tastes and smells when you shower or make coffee. Over time, iron deposits can build up in your water heater and plumbing, making them less efficient and possibly shortening their life. Appliances like dishwashers and washing machines may work harder, using more detergent and energy.\u003c\/p\u003e\n\n\u003ch3\u003eHow This System Fixes It\u003c\/h3\u003e\n\u003cp\u003eThis filter uses a process called air injection oxidation combined with a special filtering media named Katalox-Light®. The system injects air into your water to turn dissolved iron and sulfur into solid particles that the filter media then traps and removes. This method doesn’t rely on adding harsh chemicals like chlorine or potassium permanganate, making it simpler to operate and maintain.\u003c\/p\u003e\n\n\u003ch3\u003eWhat This System Can Handle\u003c\/h3\u003e\n\u003cp\u003eThe WSP Whole House Iron \u0026amp; Sulfur Filter tackles iron and sulfur together, plus manganese and some other metals often found alongside them. Its 10-inch by 54-inch tank holds 1½ cubic feet of Katalox-Light® media, offering a strong capacity that suits most homes. It works efficiently for flow rates common in residential use, with demand-based regeneration that backwashes (cleans) the media only when needed. This helps keep water pressure steady and reduces the time and water used for maintenance. It can handle well water with moderate to high iron and sulfur levels, making it a good choice if you’ve struggled with simpler filters or separate systems.\u003c\/p\u003e\n\n\u003ch3\u003eWhat You Actually Get\u003c\/h3\u003e\n\u003cp\u003eWith this system, you receive a black polyglass mineral tank covered by a lifetime warranty on the tank itself. The included control valve manages the filtration cycles using advanced Control Flow Technology but carries its own manufacturer warranty. A bypass valve comes standard, letting you isolate the filter for service while keeping water running to your home—a convenience often sold separately by others. You’ll also get 10 feet of discharge hose for the drain line, ready for your plumber’s installation.\u003c\/p\u003e\n\n\u003ch3\u003eIs This the Right Size for You?\u003c\/h3\u003e\n\u003cp\u003eThis filter fits most single-family homes with typical water usage and moderate to high iron and sulfur levels. If your household is very large, or your water has extremely high contaminant levels, you might require a larger or custom-sized system. Conversely, for low iron or sulfur levels, a smaller, simpler filter might suffice. Our team will help confirm the right size once they understand your water conditions and usage.\u003c\/p\u003e\n\n\u003ch3\u003eLiving With It\u003c\/h3\u003e\n\u003cp\u003eMaintenance mainly involves periodic backwashing triggered automatically by the system’s control valve. This process flushes out trapped particles to keep the media clean. You’ll need to ensure the drain line is clear and occasionally check the bypass valve for proper operation. While the system avoids recurring chemical additions, the control valve and electronics require normal care as detailed by the manufacturer. Your local plumber can handle any routine service or repairs using available parts.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Won’t Do\u003c\/h3\u003e\n\u003cp\u003eThis filter reduces iron, sulfur, manganese, and some other metals, but it doesn’t soften water or remove hardness minerals like calcium and magnesium. If hard water scale is also a concern, you would need a separate water softener. It also doesn’t filter out bacteria, viruses, or sediment, so additional treatment may be necessary if those are issues.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Buy It From Us\u003c\/h3\u003e\n\u003cp\u003eWater Softener Plus offers this house-brand system with genuine, serviceable components backed by a lifetime warranty on the tank.
