Well Pump Repair — No Water — Prince Frederick, MD
A Prince Frederick homeowner lost water completely on a weekday morning. Electrical diagnosis pointed to a failed pressure switch — not the pump. We replaced the pressure switch and restored water in under two hours, saving the homeowner a costly pump pull.
The Problem
A Prince Frederick homeowner called us with no water. The pump breaker was not tripped. They assumed the pump had failed and were bracing for a major repair bill.
Our Diagnosis
We performed a systematic electrical diagnosis. Voltage was present at the pressure tank disconnect. We checked the pressure switch contacts — they were not closing. The pressure gauge read zero, confirming the switch was not sensing pressure and not sending power to the pump. The pressure switch had failed in the open position. This is a common failure mode and costs a fraction of a pump replacement.
The Repair Process
- 1Confirmed breaker not tripped — power present at disconnect
- 2Checked pressure switch contacts — not closing at zero pressure
- 3Confirmed pressure gauge at zero — switch failure, not pump failure
- 4Replaced Square D 40/60 pressure switch with new unit
- 5Verified wiring connections and tightened terminals
- 6Restored power — pump started immediately
- 7Confirmed pressure rose to 60 PSI cut-out and pump stopped
- 8Checked for leaks at switch fitting — none found
The Outcome
Water restored in under two hours. Pressure switch replacement cost the cost of the repair in parts and labor — compared to the cost of the repair for a pump pull and replacement. Homeowner relieved to avoid the larger repair.
Key Takeaway
No water does not always mean a failed pump. A systematic electrical diagnosis — starting at the pressure switch — can identify a the cost of the repair part failure before you spend the cost of the repair on a pump pull. Always diagnose before you pull.

"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."
