Well Pump Keeps Running and Won't Shut Off
A pump that runs constantly is burning out fast. Here are the four causes, ranked from cheapest to most expensive, with what each one feels like.
A well pump that keeps running and never shuts off is a pump whose pressure switch is never seeing the cut-out pressure that tells it to stop. The cause is almost always one of four things: a waterlogged pressure tank, a leak somewhere in the system, a stuck or miscalibrated pressure switch, or a failing pump that can no longer build pressure. Every minute it runs without cycling shortens its life — diagnose it today.

How a service call works
- 1Free phone diagnosis
We walk through symptoms, water pressure, sounds, and system age to narrow the problem before we roll a truck.
- 2On-site test
We check voltage at the pressure switch, draw amps on the pump, and verify pressure tank pre-charge before opening anything.
- 3Written estimate
You see the recommended scope, repair vs replacement, parts, and labor in writing before any work begins.
- 4Repair or replacement
We carry common pumps, tanks, switches, and check valves on the truck so most no-water calls finish the same day they started.
- 5System test and follow-up
We cycle the system, confirm pressure holds, shock-chlorinate when needed, and stand behind the work with a labor warranty.
What does it cost?
Cheapest fix is a tank re-charge or pressure switch swap at $150 to $450. A failed pressure tank runs $400 to $1,200 installed. A pump that has lost head and needs replacement runs $1,500 to $3,500.
- •Free phone diagnosis

Frequently asked
Is it bad to let the pump run constantly?
Yes. Continuous run burns out the motor windings, overheats the pump, and can damage the pressure switch and starting capacitor. A pump that should last 12 years can die in months running constantly.
How do I know if it's the tank or the pump?
Tap the side of the pressure tank top to bottom. A waterlogged tank sounds solid the whole way — that's almost always the cause. If the tank sounds normal (hollow top, solid bottom), the cause is more likely a leak or a failing pump.
Could it be a leak in the house?
Yes. A running toilet flapper, a hidden slab leak, or a leaking irrigation valve will keep the pump cycling. Shut off the main into the house — if the pump still runs, the leak is between the well and the house.
How much does well pump repair cost?
Most residential well pump repairs in central NC fall between $400 and $1,800 depending on the failed part, well depth, and whether the pump has to come out of the well. A full submersible pump replacement (pump, wire, drop pipe, and labor) typically runs $1,500 to $3,500. Every job gets a written on-site estimate before any work begins.
