7 Signs of a Failing Well Pump (and What to Do)

Why recognizing a failing pump early matters

A well pump that fails completely can leave your household without water unexpectedly. Catching the warning signs early gives you time to get quotes, compare contractors, and schedule the replacement on your schedule rather than under emergency conditions. Emergency well pump calls typically cost 20 to 50 percent more than scheduled jobs. Use our well pump replacement cost calculator to estimate what the repair or replacement will run before you call.

7 warning signs your well pump is failing

1. Low or dropping water pressure

If your faucets, showers, or irrigation suddenly deliver noticeably less pressure than they used to, the pump may be losing capacity. Gradual pressure loss over weeks or months often points to a pump that is wearing out rather than a sudden pipe break. Confirm that the pressure tank is not waterlogged first (a waterlogged tank mimics pump failure), but if pressure remains low after checking the tank, the pump is the likely culprit.

2. Air spitting from faucets

Sputtering water that alternates between a strong stream and bursts of air suggests the pump is losing prime or drawing air along with water. In a submersible setup, this can mean the pump is running dry because the water table has dropped, or the pump intake screen is clogged or damaged.

3. Pump runs constantly or cycles rapidly

A properly functioning pump cycles on, fills the pressure tank, shuts off, and stays off until pressure drops again. If your pump runs without stopping, short-cycles on and off every few seconds, or you hear it running when no water is being used, something is wrong. Rapid cycling often points to a failed pressure tank bladder, but a worn pump that cannot build adequate pressure will also short-cycle.

4. Cloudy or sandy water

Sudden cloudiness, sediment, or sandy grit in the water supply can indicate that the pump intake screen has failed or the pump is drawing in material from the bottom of the well. This can damage the pump further if left unaddressed.

5. Higher electric bills without explanation

A well pump that is struggling to do its job draws more electrical current. If your utility bills spike with no other explanation, a failing pump motor running inefficiently may be the cause. A contractor can check amp draw against the motor's rated specs to confirm.

6. No water at all

Complete loss of water can mean the pump has seized, the electrical supply to the pump has failed, or a fuse or breaker has tripped. Check the breaker panel first. A tripped breaker that keeps tripping after reset is a red flag for a failing motor. A licensed well pump contractor can test for motor continuity and confirm whether the pump needs to be pulled and inspected.

7. Pump is over 10 years old and showing any of the above

Well pumps typically last 10 to 15 years. An older pump exhibiting any of the symptoms above is a strong candidate for replacement rather than repair. Repair parts for aging pumps can be difficult to source, and the labor to pull and re-seat a pump for a repair costs nearly as much as pulling it for a full replacement.

What to do when you suspect pump failure

• Check the breaker panel and reset any tripped breakers once.
• Check the pressure switch (a small box near the pressure tank) for obvious damage or burned contacts.
• Do not repeatedly try to run a pump that keeps tripping the breaker, as this can burn out the motor.
• Call a licensed well pump contractor for a diagnostic visit. Most charge $75 to $150 for a service call and assessment.

Get quotes from a licensed well pump contractor before authorizing major repair or replacement work. An assessment visit is money well spent if it clarifies whether you need a full swap or a simpler fix.

Frequently asked questions

How long does a well pump last before it shows these signs? Most residential well pumps last 10 to 15 years. Hard water with high mineral content can shorten lifespan to 8 to 10 years. Very deep wells also tend to wear pumps faster due to higher operating pressures.

Can a pressure tank mimic pump failure symptoms? Yes. A waterlogged pressure tank (failed bladder) causes rapid cycling that looks and sounds like a failing pump. A contractor can test tank precharge pressure in minutes to rule it out before pulling the pump.

Is it worth repairing a well pump or just replacing it? If the pump is under 7 years old, certain repairs (pressure switch, check valve, capacitor) can make sense. Pumps over 10 years old are generally better candidates for full replacement, especially when the labor cost to pull the pump is nearly the same regardless of whether you repair or replace the unit itself.

Bottom line

Low pressure, air in the lines, constant running, and sandy water are the most common early warnings. Catching a failing pump early saves money versus an emergency replacement. If your pump is over a decade old and showing any of these signs, get quotes now rather than waiting for a full failure. Use our well pump cost calculator to budget for the replacement, and have a licensed well pump contractor confirm the diagnosis before spending on parts.
