Iron Filter Installation in Maryland

Iron in well water is nearly universal throughout Calvert County, Anne Arundel County, and Charles County. The local geology produces groundwater with elevated iron and manganese that causes orange staining on everything it touches — sinks, toilets, tubs, laundry, and even concrete driveways where hose water runs.

There are several types of iron in well water, and they require different treatment approaches. Dissolved (ferrous) iron is clear when it comes out of the tap but turns orange when exposed to air. Particulate (ferric) iron is already orange when it comes out of the tap. Iron bacteria is a different problem entirely — it creates a slimy orange-brown buildup and requires shock chlorination in addition to filtration.

Iron filter sizing matters enormously. An undersized iron filter will be overwhelmed by high iron levels and pass iron through to your softener and appliances. We size iron filters based on your actual iron concentration, water flow rate, and household demand — not a one-size-fits-all approach.

Installation order is equally critical. The iron filter must be installed before the water softener. Iron will foul softener resin, destroying it prematurely and requiring expensive replacement. We see this mistake regularly in homes where equipment was installed by someone without proper water treatment expertise.
