Iron Filter Installation — Chesapeake Beach, MD
A Chesapeake Beach homeowner had orange staining on every fixture, orange-tinted laundry, and a metallic taste in the water. Water test showed iron at 4.2 ppm — well above the 0.3 ppm aesthetic standard. We installed a Pentair iron filter and the staining stopped within one week.
The Problem
A Chesapeake Beach homeowner contacted us about orange staining on their toilets, sinks, tubs, and shower walls. Their laundry was coming out with orange tints. The water had a metallic taste. A water test confirmed iron at 4.2 ppm — more than 14 times the 0.3 ppm EPA aesthetic standard.
Our Diagnosis
Iron at 4.2 ppm was causing all reported symptoms. The iron was primarily ferrous (dissolved) iron — the type that causes staining when it oxidizes on contact with air and surfaces. pH was 7.0 and manganese was 0.08 ppm (below the 0.05 ppm standard but present). An oxidizing iron filter (air injection or greensand) was the appropriate solution.
The Repair Process
- 1Comprehensive water quality test — iron 4.2 ppm, manganese 0.08 ppm, pH 7.0, hardness 12 gpg
- 2Selected Pentair air injection iron filter for ferrous iron at this concentration
- 3Installed iron filter at point of entry
- 4Set backwash cycle for every 3 days based on iron load
- 5Post-installation test confirmed iron below 0.05 ppm from all fixtures
- 6Recommended water softener for 12 gpg hardness — homeowner deferred
The Outcome
Iron reduced from 4.2 ppm to below 0.05 ppm. Orange staining stopped within one week. Laundry returned to normal color. Metallic taste eliminated. Homeowner reported the improvement was immediately noticeable.
Key Takeaway
Iron staining is one of the most visible signs of water quality problems in Southern Maryland. At 4.2 ppm, the staining is aggressive and will damage fixtures over time. An iron filter at the point of entry protects the entire home — fixtures, appliances, water heater, and laundry.

"We recently had Deep Dive Plumbing Maryland out to our home in Annapolis after we suddenly started noticing sewer flies throughout the house. They truly lived up to their name and performed a full "deep dive" diagnostic inspection instead of just treating the symptom. During their inspection they discovered our sewer pipe connected to the toilet had been leaking into the basement for quite some time. The team explained everything clearly, provided upfront pricing before starting any work, and even gave us a military discount which was greatly appreciated. They were professional, respectful, extremely knowledgeable, and took the time to make sure the repair was done correctly."

"Great service with knowledgeable and neat professionals. Highly recommend! Deep Dive Plumbing helped with my bathroom project, including reinstalling a pedestal sink after new flooring was installed and addressing a toilet issue that had been causing constant clogs. The team was professional, courteous, and took the time to make sure everything was completed correctly. Their attention to detail and cleanliness really stood out. I am very happy with the results and would not hesitate to call them again."
