Well Water Problems: Complete Troubleshooting Guide
📋 In This Guide
Quick Answer: Most well problems fall into a few categories: no water, low pressure, dirty/smelly water, or pump issues. Start with the simple checks (breaker, pressure switch) before assuming major problems. This guide covers the most common issues and their solutions.
No Water at All
Check First
- Circuit breaker: Is it tripped? Reset it.
- Power outage: Check other appliances
- Pressure switch: Listen for click when pressure drops
Possible Causes
| Symptom | Likely Cause | Solution |
|---|---|---|
| Breaker trips repeatedly | Pump motor problem, short circuit | Call professional |
| No power to switch | Wiring issue, breaker | Check connections |
| Switch clicks but pump doesn't run | Bad capacitor, motor failure | Replace component |
| Pump runs but no water | Well dry, broken pipe, pump failure | See detailed guide |
Low Water Pressure
Quick Checks
- Check pressure gauge—what does it read?
- When were filters last changed?
- Is it low everywhere or just one fixture?
Common Causes & Fixes
| Symptom | Cause | Fix |
|---|---|---|
| Low everywhere | Pressure switch set low | Adjust switch settings |
| Pressure fluctuates wildly | Waterlogged tank | Recharge or replace tank |
| Gradual decline over time | Clogged filters, worn pump | Replace filters, service pump |
| Low only when multiple fixtures on | Undersized pump or low yield well | Upgrade pump or add storage |
Dirty or Cloudy Water
Identify the Type
- Muddy/brown after rain: Surface contamination
- Orange/red: Iron
- Black specs: Manganese or pipe corrosion
- Milky/white: Air bubbles (harmless) or bacteria
- Sandy/gritty: Sediment, possible pump or screen issue
Solutions
| Problem | Cause | Solution |
|---|---|---|
| Brown after rain | Damaged well cap or casing | Inspect and repair well |
| Orange/red staining | High iron | Iron filter system |
| Sand in water | Pump too low, failed screen | Adjust pump, inspect well |
| Cloudy always | Various—get tested | Water test, then treat |
Bad Smell or Taste
Identify the Smell
- Rotten eggs: Hydrogen sulfide (sulfur)
- Musty/earthy: Organic matter, bacteria
- Metallic: Iron, manganese, low pH
- Chlorine: Recent shock treatment (temporary)
- Petroleum/chemical: Contamination (serious)
Solutions
| Smell | Cause | Treatment |
|---|---|---|
| Sulfur (rotten eggs) | H2S gas, bacteria | Aeration, oxidation filter |
| Only in hot water | Water heater anode | Replace anode rod |
| Metallic taste | Iron, low pH | Iron filter, neutralizer |
| Chemical smell | Contamination | Stop using, test water, investigate |
Pump Problems
Pump Won't Start
- Check breaker and reset if tripped
- Check pressure switch contacts
- Listen for hum (may indicate bad capacitor or stuck pump)
- If breaker trips immediately = motor or wiring problem
Pump Won't Stop
- Leak in system (most common)
- Can't build pressure (worn pump)
- Stuck pressure switch
- Turn off immediately to prevent motor damage
Pump Cycles Rapidly
- Waterlogged pressure tank (most common)
- Small leak
- Failing check valve
Pressure Tank Problems
How to Check Tank
- Tap from top to bottom
- Top should sound hollow (air)
- Bottom should sound solid (water)
- If all solid = waterlogged
Waterlogged Tank
- Symptoms: Rapid cycling, pressure swings
- Cause: Lost air charge or failed bladder
- Fix: Recharge air or replace tank
Tank Not Holding Air
- Bladder has ruptured
- Air valve leaking
- Tank replacement usually needed
When to Call a Professional
- Electrical problems (sparking, burning smell)
- Pump needs to be pulled from well
- Repeated breaker trips
- Chemical contamination suspected
- You're not comfortable with the repair
- Problem persists after basic troubleshooting

Frequently Asked Questions
How do I know if my well pump needs repair?
Common signs include: no water or low pressure, pump cycling on and off rapidly (short cycling), unusual noises, dirty or sandy water, and higher-than-normal electric bills. Any of these warrant a professional inspection.
How much does well pump repair cost?

Surface-level issues like pressure switch adjustment or breaker resets are safe DIY tasks. However, anything involving pulling the pump from the well requires specialized equipment and should be handled by a licensed contractor to avoid damaging the well casing.
