Including filter system and high-performance Manganese Staining filter.
Manganese staining appears as dark brown or black marks on sinks, tubs and toilets, and can leave laundry looking dingy or spots on dishes. Even if the water coming from your Scanlon tap seems clear, manganese may oxidize after it meets air and cause stubborn discoloration. Some homeowners also notice a metallic taste or fine sediment that settles in a glass — signs that stains will keep returning despite regular cleaning.
Manganese is a natural mineral that can enter household water from certain groundwater sources and may change over time. When present it tends to cause staining on fixtures and inside plumbing rather than just an off taste, and hot water often makes the discoloration more visible in showers, tubs and laundry. If your Scanlon home sees recurring stains, that pattern usually points to the source water rather than your cleaning methods.
The single most effective whole-house solution for reducing manganese staining is an oxidation-and-filtration media tank installed at your point of entry. This system oxidizes dissolved manganese and traps the resulting particles in the media so they’re removed before reaching bathrooms, appliances and laundry in your Scanlon home. Treating the water at the main line stops the ongoing cycle of buildup and cleaning by addressing the contamination itself rather than merely hiding the stains.
Oxidation media filters are usually paired with an automatic control valve that backwashes the tank to flush trapped particles and maintain consistent performance as manganese levels and household water use vary. Because manganese’s behavior can depend on pH and whether other minerals like iron are present, proper sizing and media choice are important. Mr. Pure Water works with Scanlon homeowners to select the right whole-house configuration so staining is reduced at every tap.
