The Definitive SWPA Water Treatment Resource

Water softeners can handle low levels of dissolved iron—typically under 1-2 mg/L depending on conditions. But most well water in Southwestern PA has iron levels above that threshold, often 3-10+ mg/L. At those concentrations, iron fouls the softener resin and reduces its effectiveness. A dedicated iron filtration system with Custom-Designed media is the proper solution for moderate to high iron.

You have “clear water iron” (ferrous iron)—it’s dissolved and invisible in the water. When it contacts air (like when water splashes on a surface), it oxidizes and turns orange. This is the most common form in our area and requires an oxidation step before filtration to convert the dissolved iron into particles that can be captured.

Iron in water is a dissolved mineral. Iron bacteria are living organisms that feed on iron and create slimy, reddish-brown biofilm inside pipes, toilet tanks, and fixtures. Iron bacteria also produce unpleasant odors. Treatment for iron bacteria is more involved—it typically requires aggressive oxidation (sometimes chlorination) combined with filtration, not just filtration alone.

The EPA secondary standard for iron is 0.3 mg/L—above that, staining becomes noticeable. Manganese staining starts even lower at 0.05 mg/L. These aren’t health-based standards (iron and manganese at typical well water levels aren’t dangerous), but they represent the point where cosmetic and practical problems begin. Most of our customers have iron between 1-10 mg/L.

A properly sized system should not noticeably reduce water pressure. We design systems around your well’s flow rate and your household demand. Undersized systems cause pressure drops; that’s why we test flow rate as part of our assessment. The system we install matches your actual capacity.

Iron filters periodically backwash—reversing water flow through the media to flush out captured iron and manganese particles. This happens automatically on a programmed schedule (usually overnight). The backwash water goes to drain. A properly programmed backwash cycle keeps the media clean and effective for years.

Custom-Designed filtration media typically lasts several years before needing replacement, depending on iron and manganese levels, water usage, and proper maintenance. We’ll give you a realistic timeline based on your specific water chemistry. Media replacement is a standard service call—not a full system replacement.

Yes. We service iron removal systems regardless of who installed them. Common issues include exhausted media, improper programming, insufficient backwash, or pH problems that prevent the media from working correctly. We’ll test your water, evaluate your equipment, and give you honest options—repair, reprogramming, media replacement, or system redesign if needed.

Often, yes. Iron filtration handles iron and manganese; a water softener handles hardness (calcium and magnesium). In our region, well water frequently has both problems. We design multi-stage systems where iron is treated first, then hardness—each stage optimized for its specific job.

Call us at 724-708-8816 or fill out the form below. We’ll schedule a water test to measure your iron, manganese, pH, and other relevant parameters. From there, we design a system matched to your actual water chemistry. No guessing, no pressure.
