Well Pump Replacement in Huntingtown, MD

The Problem

A homeowner in Huntingtown, MD (20639) had been experiencing intermittent water pressure drops for several months — the pressure would be fine in the morning but drop significantly by afternoon, especially when multiple fixtures were in use.

The well pump was 14 years old. A neighbor had recently replaced their pump after similar symptoms, and the homeowner suspected the same issue.

The Diagnosis

We performed a full well system diagnostic. The pressure tank was functioning correctly — it had a proper air charge and was cycling normally. The pressure switch settings were correct.

We pulled the pump and inspected it. The impeller showed significant wear — the pump was producing only about 60% of its rated flow. At 14 years old with the well water quality in this area (moderate iron and hardness), this level of wear was expected.

We also performed a water quality test as part of the diagnostic. The results showed elevated iron (2.8 ppm), moderate hardness (12 gpg), and a pH of 6.4 — slightly acidic. These water quality issues had accelerated the pump wear and would affect the lifespan of a new pump if not addressed.

The Solution

We replaced the submersible pump with a new 1/2 HP unit rated for the well depth (180 feet). We also replaced the drop pipe, safety rope, and electrical connections — standard practice when pulling a pump at this depth.

We recommended a whole-home water filtration system to address the iron, hardness, and pH issues. The homeowner chose to install an acid neutralizer and iron filter at the same time as the pump replacement.

The filtration system was installed at the pressure tank, treating all water entering the home. This protects the new pump from the water quality issues that shortened the previous pump's life.

The Outcome

Full water pressure restored immediately. The homeowner now has consistent pressure throughout the home. The water quality improvements — no more orange staining, no more metallic taste — were an unexpected benefit they had not anticipated.

Key Takeaways

• Well pump lifespan is significantly affected by water quality
• Iron and acidic water accelerate pump wear and reduce lifespan
• Addressing water quality at the time of pump replacement protects the new pump
• A full diagnostic identifies all contributing factors, not just the failed component
• Replacing drop pipe and connections during pump replacement is standard best practice
