Repair when the fault is above ground (pressure switch, capacitor, control box or wiring) or the pump is young. Those repairs typically cost $150–$600. Replace when the motor is shorted or burned out, the pump end is worn, or the pump is 10+ years old with repeated failures. Replacement typically costs $1,800–$4,500 at Parker County settings.
Water Well Drilling Weatherford is asked to repair or replace a well pump on most no-water calls. The answer depends on facts you can measure: where the fault is, how old the pump is, and what else is wearing it out.
Step 1: Where is the fault?
Before anything comes out of the well, a tech should test from the surface:
- Voltage and amp draw at the control box and switch
- Pressure switch contacts and settings
- Capacitor and relay in the control box (on three-wire pumps)
- Insulation (megohm) reading of the wire and motor
- Tank pre-charge
HomeGuide’s 2026 data puts electrical faults at about 30% of well pump service calls. Those are usually repairable above ground.
Step 2: Compare the costs
| Repair | Typical 2026 cost |
|---|---|
| Pressure switch | $150–$300 installed |
| Control box | $200–$400 installed |
| Start capacitor | $75–$200 |
| Service call | $150–$250 |
| Submersible pump replacement (Parker County settings) | $1,800–$4,500 |
Step 3: Weigh the pump’s age
| Situation | Usually the better call |
|---|---|
| Fault in switch, control box or wiring, any age | Repair |
| Motor shorted or open, pump under ~8 years | Replace the pump; find what killed it early |
| Motor or pump end failed, pump 10+ years old | Replace |
| Pump runs but can’t build pressure, 10+ years | Replace after checking pipe and water level |
| Repeated failures in the last few years | Replace, and fix the tank or water-level cause |
Step 4: Fix the cause, not just the pump
Pumps rarely just die. In Parker County the common culprits are:
- Short cycling from a waterlogged or undersized pressure tank.
- Running dry as summer water levels fall toward a shallow pump setting.
- Sand wearing the impellers when the pump sits too close to the bottom.
- Lightning and surges during spring storm season.
Replacing a pump without fixing the cause buys another short run. When the pump is out, we measure the water level, inspect the pipe and wire, and size the new pump and tank together. See well pump replacement cost and well pump repair.
Bottom line
Test before you pull. If the fault is in the switch, control box or wiring, repair it. If the motor or pump end has failed and the pump is 10 or more years old, replace it, and fix the tank or water-level problem that shortened its life while the well is open.
