Iron Filter Installation — Deale, MD
A Deale homeowner had orange staining on every fixture and a metallic taste in their water. We tested the water, confirmed 4.2 PPM iron, and installed a whole-house iron filter. Staining stopped within two weeks.
The Problem
A homeowner in Deale called us about orange staining on their toilets, sinks, and shower — and a metallic taste in their drinking water. They had tried a pitcher filter for drinking water but the staining on fixtures was getting worse. Their water came from a private well.
Our Diagnosis
We performed a comprehensive water test on-site. Results: iron at 4.2 PPM (EPA secondary standard is 0.3 PPM), manganese at 0.08 PPM, pH at 6.4 (slightly acidic), and hardness at 12 GPG. The high iron was the primary cause of the staining and metallic taste. The low pH was accelerating corrosion of the plumbing and water heater. We recommended a whole-house iron filter with an acid neutralizer to address both issues.
The Repair Process
- 1Performed full water analysis: iron, manganese, pH, hardness, sulfur, bacteria
- 2Reviewed results with homeowner — explained each parameter and its effects
- 3Recommended Pentair iron filter (air injection oxidation) + calcite acid neutralizer
- 4Installed the iron filter in the basement utility room — before the pressure tank
- 5Installed calcite acid neutralizer in series after the iron filter
- 6Set filter backwash cycle to 2 AM daily — minimal water waste, maximum effectiveness
- 7Ran water through all fixtures — confirmed clear water at all points
- 8Scheduled 30-day follow-up water test to confirm iron levels at zero
The Outcome
The homeowner reported clear water from all fixtures within 48 hours of installation. At the 30-day follow-up test, iron was undetectable (<0.05 PPM) and pH had risen to 7.2 — within the ideal range. The orange staining on fixtures faded over the following two weeks as the iron deposits dissolved. The homeowner's water heater will now last significantly longer without iron sediment accumulation.
Key Takeaway
Iron at 4+ PPM requires a whole-house treatment system — pitcher filters and under-sink units cannot handle the volume. An air injection iron filter is the most effective solution for high-iron well water in Southern Maryland.

"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."
