1. Pressure that fades or pulses
If the shower starts strong and then weakens, or pressure surges up and down, the pump may be wearing and unable to keep up. But this is also the classic sign of a waterlogged pressure tank, so check the tank first. It's cheaper.
2. The pump runs constantly
A pump that never shuts off may be worn and unable to reach the cut-off pressure. There may be a leak somewhere, like a running toilet, a broken yard line or a split pipe in the well, or the switch may be stuck. Listen for the pump with every tap closed. If it still runs, something is drawing water or the pump can't build pressure.
3. Rapid clicking on and off
Short-cycling (on for a few seconds, off for a few seconds) is hard on any motor. The usual cause is the tank, not the pump, but left alone it's a common reason pumps fail early.
4. Sputtering faucets or air in the lines
Air spitting from the taps can mean the water level in the well is dropping to the pump intake, a leak in the drop pipe, or a failing check valve. In a dry late summer, low-yield wells in parts of Orange County can show this during heavy use.
5. Sand, silt or sudden cloudiness
A pump that starts pulling sediment can be damaged by it. It can also be a sign the pump is set too low, or that something changed in the well. Get it looked at, and test the water if it stays cloudy.
6. Higher electric bills
A pump that runs longer to do the same work, or a motor drawing too much current, shows up on the electric bill. Unexplained jumps are worth a check, especially when combined with any sign above.
7. The breaker trips
A breaker that trips once after a storm may be a one-off. A breaker that trips again right after a reset points to a short, a seized pump, or a failing control box. Stop resetting it and call.
Not always the pump
Pressure switches, control boxes, tanks and check valves cause a big share of "pump" problems. A good technician measures before replacing. Ask what readings led to the recommendation.
What Replacement Typically Costs
Submersible pump replacement often runs about $1,000–$2,800, depending on well depth, pump size and whether wire or pipe is replaced. That's a typical range, not a quote. See well pump repair & replacement.
Questions
How long do well pumps last?
It depends heavily on water quality, sediment, tank condition and how often the pump cycles. Many run for a decade or more. Short-cycling and sediment are the usual reasons for early failure.
Can I replace a submersible pump myself?
It involves lifting a long, heavy assembly out of the well and working with 240-volt wiring. Most homeowners leave it to a well contractor with a pump hoist.
