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 clothes and dishes looking dingy. Even if your tap water looks clear, manganese may oxidize when exposed to air and form stubborn discoloration or fine sediment that settles in a glass. You might also detect a faint metallic taste. In Benbow’s humid subtropical climate and with our region’s hard water tendencies, those stains can be especially noticeable on fixtures and surfaces.
Manganese is a natural mineral that can come from groundwater sources and change over time, often showing up as more of a staining problem than just a flavor issue. It tends to accumulate on plumbing and fixture surfaces, and hot water can make the discoloration more apparent in showers, tubs and laundry. If you keep scrubbing but the marks return, that’s usually a sign the mineral is in your water supply rather than a cleaning issue inside the home.
The most effective single-filter solution for reducing manganese staining in a Benbow home is an oxidation-and-filtration media tank installed as a whole-house system. This filter oxidizes dissolved manganese so the media can trap it, stopping the mineral before it reaches bathrooms, appliances and laundry. Installed at the point of entry, it prevents the repeated cycle of staining and cleaning by addressing the source rather than simply hiding the problem.
An oxidation media tank normally works with an automatic control valve that backwashes to remove captured particles and keep performance consistent as water use and manganese levels change. Because manganese can act differently depending on pH and whether iron or other minerals are present — and given Benbow’s limestone-aquifer–influenced hard water — correct sizing and media choice are important. Mr. Pure Water will evaluate your house water and recommend the right whole-house configuration so staining is reduced at every tap.
