"Fantastic service. This is the second time we've hired R & G Water Systems. Both times we had an issue in the middle of the night and they were able to send someone out first thing in the morning. They replaced our well pump the same day (within a few hours of calling actually). This went as smoothly as the first time we hired them and would definitely continue to use them."

"Always communicated when to expect technician/crew including names and photos. Wayne and crew provided excellent service. We had a trench installed to move the sump pump discharge away from the house."

"Our water heater died, and was leaking. We called after hours, and owner answered the phone. Technician came out next day, and he showed up on time and replaced the heater. Plumber was very courteous, professional, and helpful with advice. No complaints - work is guaranteed. Only downside: price for the water heater itself was high - could have bought comparable unit much cheaper at HD or Sears, but would then have needed to have it delivered and installed by the plumber anyway. Their work is was very good, which was most important and we would definitely use them again."

FAQs for well pump repair or service projects in Gaithersburg, MD

A standard well inspection begins with a visual inspection of the pump, casing, storage tank, and wiring, followed by flow rate tests and laboratory-based water sampling. The goal is to confirm that every part meets safety standards and to identify any necessary repairs before they become expensive. An inspector will also test your water quality for substances such as volatile organic compounds and any local containment concerns.

Book a licensed, insured well specialist for your inspection. Many well‑pump contractors also hold inspection credentials. They’ll bring the right tools to assess the pump, wiring, and water quality, and provide you with a clear report on any necessary fixes. Before you hire, confirm their license, insurance, and recent customer reviews.

Plan on a full well inspection every year. You’ll also want one any time the cap comes off, after septic repairs, or if flooding occurs. Annual tests look for total and fecal coliform; every two years, the lab should screen for metals and nitrates, and every five years for VOCs and pesticides. If you’re buying a home with a private well, it’s essential to schedule a pre-purchase inspection.

With routine care, most wells supply clean water for up to 40 years. Lifespan depends on the type and how well you protect it. To help it reach the maximum lifespan, keep hazardous products far from the casing, ensure the cap stays sealed, schedule yearly inspections, and address problems as soon as they appear. Good habits keep the system healthy and the water safe.

The average cost of well repairs ranges from $100 to $2,800. Your final bill depends on which part—pump, pressure tank, casing, or piping—needs attention and the level of complexity involved in the repair. A thorough inspection identifies the problem, allowing you to budget accurately and avoid paying for unnecessary parts or services.
