Well problems a plumber sees
| Symptom | Common cause |
|---|---|
| Pressure surges and pump short-cycling | Waterlogged pressure tank or failed switch |
| No water at all | Pump, power or pressure switch failure |
| Rusty or metallic water | Iron or manganese in the groundwater, or corroded pipes |
| Rotten-egg smell | Hydrogen sulfide in the well or a water heater anode reaction |
When to retest
Test after any repair that opens the well, after flooding near the wellhead, or if taste, color or smell changes. Treatment equipment like softeners and filters should be chosen from test results, not guesses; see water filtration systems and well pump repair.
