Start with the symptom. Avoid the guesswork.
A pump that runs without delivering water and a pump that cycles too often can have completely different causes. Use observable symptoms to narrow the next step safely.
Which symptom fits?
No water at any faucet
Check whether the entire home is affected; note the gauge reading and whether a breaker has tripped. Do not repeatedly reset a tripped breaker or dry-run a pump.
Next step: A licensed well or pump professional can safely check controls, motor and well yield.
Low pressure or weak flow
Check whether the problem affects hot and cold water, one fixture or the entire home. Note how pressure behaves while water is being used, and inspect accessible filters for clogging.
Next step: Compare filter condition, pressure readings, system demand and pump capacity.
Frequent on/off cycling
Short cycling may be caused by tank precharge problems, a damaged bladder, leaks, or pressure-control faults. Avoid adjusting controls before understanding the system and isolating power.
Next step: Review pressure tank basics.
Pump won’t stop running
Possible causes include a leak, inadequate water supply, an underperforming pump or a pressure switch that never reaches its cut-out setting. A continuously running pump can overheat.
Next step: Arrange prompt troubleshooting instead of letting a dry pump run.
Record these details before calling for service
- Pump type (submersible or jet) and approximate age.
- Pressure switch range, such as 30/50 or 40/60 psi, if labeled.
- Gauge reading with faucets closed and while water flows.
- Whether the problem started suddenly or developed gradually.
- Filter changes, recent plumbing work or unusual electrical symptoms.
