Well Pump Problems and Troubleshooting
Well Pump Runs but No Water Reaches the House
It's a confusing situation: you can hear the pump running, so it has power — but no water comes out of the taps. This usually means the pump is operating without actually moving water to the house, and there are a handful of common reasons. Because a pump running dry or against a blockage can damage itself, this one deserves prompt attention.
The good news is that a running pump tells you the electrical supply and controls are largely doing their job — the breaker is holding and the pressure switch is calling for the pump. That narrows the search to the mechanical side and the water source, which is a different (and often more revealing) set of causes than a pump that stays silent.
The Pump Has Power but Isn't Delivering
When the pump runs but no water arrives, the electrical side is working — the problem is between the pump and your faucets. The pump may be spinning without picking up water, or water may be moving but not making it up and into the house. Either way, a running pump that delivers nothing is doing no useful work and, in some cases, risks overheating or wear, so it shouldn't be left running.
The distinction between a submersible pump and a surface (jet) pump matters here. A submersible sits down in the well and pushes water up; if it keeps running dry it can overheat quickly. A jet pump sits above ground and relies on being primed — full of water — to create the suction that pulls water up. Knowing which type you have shapes both the likely cause and the urgency.
Common Causes
- The well has dropped below the pump — low water level means the pump has nothing to draw.
- A jet pump that has lost its prime — a surface pump can lose the water it needs to create suction.
- A failed check valve or foot valve — water drains back down instead of staying in the line.
- A break or leak in the drop pipe — water escapes before reaching the surface.
- A worn pump — the pump spins but its components no longer move water effectively.
Why It Needs Prompt Diagnosis
A pump running without moving water can wear or overheat, and if the well has dropped low, continued running can worsen things. It's generally best not to leave the pump running in this state. Since the causes range from a simple lost prime on a jet pump to a failed component down the well, a provider identifies which applies. Our guide on how to prime relates to the jet-pump case, but diagnosis should confirm the cause rather than guessing.
Part of what a provider does is separate causes that live at the surface from those that require pulling the pump. A lost prime, a suction-side leak, or a faulty check valve near the surface can sometimes be addressed without disturbing the well, while a worn pump, a broken drop pipe, or a well that has dropped below the pump involves the equipment down the borehole. That distinction has real bearing on the scope of the work, so a careful diagnosis is worth the wait.
What to Do
Note whether the pump is a visible surface unit (jet) or down the well (submersible), when the problem started, and any recent changes like heavy water use or a dry spell. Avoid leaving the pump running if it's delivering nothing. Then request service so a licensed provider can diagnose and fix it. If the household is without water, treat it as urgent. Never open the well or electrical components in the process.

Well Pump Problems and Troubleshooting — Questions
Why does my well pump run but no water comes out?
The electrical side is working but water isn't reaching the house — commonly because the well has dropped below the pump, a jet pump has lost its prime, a check or foot valve has failed, there's a break in the drop pipe, or the pump is worn and spinning without moving water. A diagnosis identifies which.
Should I leave the pump running to try to get water?
No — a pump running without moving water can wear or overheat, and if the well is low, running it can make things worse. It's best not to leave it running in this state. Note the symptoms and request service for a proper diagnosis.
Could the well be running out of water?
It's one possibility — if the water level in the well drops below the pump (from a dry spell or heavy use), the pump has nothing to draw and runs without delivering. A provider can determine whether it's the well level or a component like a check valve or the pump itself.
Is this an emergency?
If the household has no water, treat it as urgent and request emergency service. Beyond the inconvenience, a pump running without delivering water can damage itself, so it shouldn't be left running while you wait. A licensed provider diagnoses and resolves the cause.
