Well Pump Repair and Replacement

No water, a pump that won't shut off, or a breaker that keeps tripping? Oasis Well Service handles well pump repair and replacement across Prince William, Fauquier and nearby counties, with a free diagnosis and a 5-year warranty on pump installs.

When to call for well pump repair

Most folks never think about their pump until the faucet coughs and goes quiet. A submersible pump sits down in the well where you never see it, so the first clues show up in the house. These are the calls we get most.

  • No water at all. The taps are dry and the pressure gauge sits near zero.
  • The pump runs constantly. It never seems to shut off, even when nobody is using water.
  • A tripping breaker. The well breaker keeps kicking off, sometimes right after a reset.
  • Air spitting from faucets. Sputtering taps can point to the pump, a leak in the line, or a low water level.
  • Pressure swings. The shower goes strong, then weak, then strong again.

None of these always means a dead pump. A pump that never shuts off can even be a running toilet. Pressure swings are often a tired pressure tank. That is why we diagnose before we replace anything. We would rather tell you the pump is fine than sell you one you did not need. For the full rundown, read our post on the 7 signs your well pump is failing.

What to do before you call

Keep it simple and safe. Check the well breaker in your panel. If it tripped, reset it once. If it trips again, turn it off and leave it off. Please do not open the pressure switch cover, touch any wiring, or try to pull the pump yourself. If you have no water, call our emergency line at 703-776-0996. If the power just went out, our guide on losing water after a power outage explains a common switch issue.

How we handle well pump repair and replacement

When a pump has failed, we pull it, confirm the cause, and set a new submersible pump sized for your well and your household. The pumps we put in are Gould, Myers and Grundfos. Every pump install carries a 5-year warranty, and our work meets county code.

Constant pressure systems

A constant pressure system uses a variable speed drive to hold pressure steady, so a second shower does not make the kitchen tap sag. We install them from Gould, Myers and Grundfos. They suit bigger households and anyone tired of pressure swings. If a standard pump and tank will serve you just as well, we will say so.

How long does a well pump last?

On average, 10 to 15 years. The real number depends on static water level, well depth, water quality and usage. There is no true routine maintenance for a submersible pump, but a well set tank helps. More in how long a well pump lasts.

Where we work

We cover Prince William County, Fauquier County and the surrounding counties, including Bristow, Haymarket, Warrenton and Catlett. No-water calls take priority.

Call for a free diagnosis

Diagnosis is free, within reason. We often sort out the cause on the phone before we come out. Call 703-791-3981 any time, day or night.

If the pump turns out to be fine, we say so. Plenty of calls end with a new switch, a tank recharge or a reset breaker, and we would rather earn the next call than sell a pump nobody needed.

Questions we hear a lot

How do I know if my well pump is bad or if it is something else?

No water, a pump that runs nonstop, a tripping breaker, air spitting from faucets and pressure swings can all point to the pump, but they can also be a tank, switch or line problem. The only way to be sure is a proper diagnosis. Oasis Well Service offers a free diagnosis, within reason, so call 703-791-3981.

How long does a submersible well pump last?

A well pump lasts 10 to 15 years on average. Static water level, well depth, water quality and how much water you use all play a part. Some go longer and some fail early.

Is there routine maintenance I should do on my well pump?

There is no true routine maintenance for a submersible pump. The best thing you can do is keep your pressure tank balanced to the switch setting, which protects the pump from short cycling. We can check that for you on any visit.

What warranty comes with a new well pump?

Every pump install from Oasis Well Service comes with a 5-year warranty. We install Gould, Myers and Grundfos pumps, and our work meets county code.

What is a constant pressure system and do I need one?

A constant pressure system uses a variable speed drive to hold steady pressure no matter how many taps are open. It is a good choice for larger homes or anyone bothered by pressure that rises and falls. We can tell you honestly whether it makes sense for your well.

My well pump keeps tripping the breaker. Should I keep resetting it?

Reset it once. If it trips again, turn the breaker off and leave it off, because repeated resets can damage the pump or wiring. Then call 703-791-3981, or 703-776-0996 if you are out of water.

How fast can you get here if I have no water?

No-water calls take priority. Call 703-776-0996 any hour of the day.
