How do I know if I need a well pump repair or replacement?

Common signs include no water, very low water pressure at your faucets, the pump cycling on and off frequently, unusual noises (clicking or grinding), visible leaks near the pump or pressure tank, or an older system that hasn’t been serviced in years. If you notice any of these in your Maryland home, it’s time to schedule an inspection.

We work on a full range of systems, including jet (conventional) well pumps, submersible deep-well pumps, booster pumps/constant pressure systems, pressure tanks and controls, and related well enclosures or improvements.

Yes. If you’ve lost water or have a major pressure drop, our fully-equipped trucks are ready for emergency well pump service in Maryland. Call 301-854-1333 and we’ll work to get to you as quickly as possible.

It’s a good idea to have your well system — including the pump, pressure tank, controls, and wiring — inspected at least once a year. Regular maintenance helps prevent sudden failures, reduces downtime, and extends the life of your equipment.

Yes. For low-yield wells, we design solutions such as properly sized pumps, storage tanks, and control systems that help ensure you still have a dependable water supply for everyday use.

Maintenance frequency depends on the type of system and your water quality. Sediment and carbon filters typically need replacement every 6–12 months; UV lamps are usually changed annually; and reverse osmosis membranes last 2–3 years. We offer maintenance plans to ensure your system runs efficiently and to remind you when it’s time to service or replace filters.

Simply call us at 301-854-1333 or fill out the contact form on this page. We’ll schedule a convenient time to inspect your system, explain your options, and provide a clear estimate for repair or installation.
