You turn on the faucet and nothing happens. Or it sputters, runs for 30 seconds, and stops. Or the pressure tank cycles every two seconds and the pump won't shut off. If you are on a private well in Utah, sooner or later this is going to happen — and how you respond in the first hour matters.
This guide is a calm, step-by-step troubleshooting playbook. It will help you figure out what kind of failure you are dealing with, what is safe to check yourself, and when to stop and call a licensed Utah driller. The same procedure works for homes in Iron, Washington, and Sevier counties.
Safety First
A well-pump system runs on 230-volt power and sits inside a sealed pressure system. Two firm rules: never open an electrical panel or junction box you are not qualified to work in, and never remove a pressure tank or pull a pump without depressurizing and disconnecting power. Everything in this guide is observation and reset only — anything beyond that calls for a pro.
Step 1: Confirm the Failure Mode
Different symptoms point to different problems. Identify which scenario fits:
- No water at any faucet, no pump sound. Likely electrical, pressure switch, or motor.
- Pump runs constantly, low or no pressure. Likely pressure tank, leak in drop pipe, or worn pump.
- Pump cycles rapidly on and off (every few seconds). Almost always a waterlogged pressure tank.
- Water sputters with air, or runs sandy. Likely low water level, well drawdown, or screen issue.
- Breaker keeps tripping. Short in pump motor or wiring; do not keep resetting.
Step 2: Check the Easy Stuff
Power
Walk to the breaker panel. The pump is typically on a dedicated 230V double-pole breaker labeled "well pump" or "pump." If it is tripped (handle in the middle position), reset it once. If it trips immediately or within a few minutes, stop. Do not keep resetting — you can burn out the motor or melt the wire. Call a pro.
Pressure Switch
The pressure switch is the small gray box on top of the pressure tank. Look for visible burned contacts, ant or insect intrusion, or corrosion. If you see an obvious problem, the switch is probably the culprit (a $40 part, but installation involves live 230V — call a pump tech).
Pressure Tank
With the pump off, knock gently on the side of the pressure tank. The bottom should sound dull (water filled), the top should sound hollow (air filled). If the whole tank sounds full of water, the air bladder has failed and the tank is "waterlogged" — the most common cause of rapid cycling. This is a $400-$900 replacement.
Wellhead
Walk out to the well. Make sure the cap is secure and there are no obvious signs of intrusion (rodents, water pooling, etc.). If you smell anything bad or see staining, stop drinking the water until a pro inspects.
Step 3: Diagnose Likely Cause by Symptom
Sputtering Air, Then Slowing to a Trickle
Strong indicator the well has drawn down below the pump. Especially likely in a hot, dry summer or after heavy irrigation use. Stop pumping for 4-8 hours and let the well recover. If recovery only buys you 10-30 minutes of normal use, you have a low-water emergency. See our drought-year well planning guide.
No Sound from Pump, Power Confirmed
Either the pressure switch is bad, the control box (above-ground for 3-wire pumps) has failed, or the pump motor itself is gone. A pump tech can usually diagnose by amp-clamp test in 15 minutes.
Pump Runs but No Water Builds Pressure
Either the pump is worn out (impellers gone), there is a hole in the drop pipe down the well, or a check valve has failed. Diagnosis requires pulling the pump.
Breaker Trips Immediately on Reset
Direct short — usually a failed pump motor, damaged wire down the well, or burned wire splice. Stop. Call a pro. Repeated reset attempts will damage your panel.
Step 4: What to Do While You Wait
- Turn off the breaker to prevent further damage if the pump is suspect.
- Use stored water sparingly. Toilet tanks, hot water heater (~40-50 gal), and any backup containers.
- Drain hot water heater into containers if you anticipate a multi-day outage.
- Buy bottled drinking water. Plan on 1 gallon per person per day for emergencies.
- Pull together your well log and pump info. Original drilling depth, casing diameter, pump make/model, install date. This saves the pro 30+ minutes when they arrive.
What an Emergency Well Repair Costs in Utah
- After-hours service call$150 - $350
- Pressure switch replacement$200 - $400
- Pressure tank replacement$600 - $1,400
- Submersible pump replacement (300-500 ft)$2,500 - $6,500
- Pump pull + drop pipe repair$1,800 - $4,500
- Wire & control box rework$400 - $1,200
Preventing the Next Emergency
Most emergency well failures in Utah are predictable from prior warning signs. The owners who never have a 2 a.m. failure are the ones who:
- Replace pumps and pressure tanks before they fail (typically every 12-18 years).
- Have a pump-saver device installed.
- Track static water level annually.
- Get an annual well checkup, especially before summer demand peaks.
