Signs a Well Pump Is Failing
The warning signs that a well pump is near the end: sputtering taps, rising electric bills, noise and sand, and what each one usually means.
Warning signs
- Air spitting from taps or sputtering water.
- The pump runs constantly or far longer than it used to.
- A jump in the electric bill with no other change in the house.
- Sand, sediment or muddy water that was not there before.
- Breaker trips when the pump starts.
- Pressure that fades during long showers or irrigation.
What each one usually means
Constant running with weak flow points to a worn pump or a leak. Sand points to a pump set too close to the bottom or a failing screen. Breaker trips point to the motor, wiring or capacitor. Rising bills come from a pump working harder for the same water. Angi says submersible pumps last 8 to 15 years and jet pumps 8 to 10, so age matters as much as symptoms.
Before you replace it
Rule out cheap parts first: a control box ($200 to $500), a capacitor ($100 to $150) and a pressure switch ($120 to $175), all Angi installed prices. Then compare repair and replacement and check the replacement cost guide.
After any repair
Opening the well can let bacteria in. EPA recommends testing private well water regularly, and many contractors disinfect the well after a pump is pulled (EPA, Private Drinking Water Wells). Your county health department, listed on our county pages, can test the water.
