Most well problems show up as one of a few symptoms: no water, low or changing pressure, a pump that won’t stop, a tripping breaker, or water that looks or smells wrong. Find your symptom below for likely causes, the few checks that are safe to make yourself, and when Wisconsin rules call for a licensed pro.

Safety first: well pumps run on 230/240-volt circuits. Don’t open the pressure switch, control box or well cap wiring.
Start with the safe checks
- Other faucets: is it every tap or just one? One tap points to house plumbing, not the well.
- Pressure gauge: read the gauge near the pressure tank and write the number down.
- Breaker: flip the pump breaker fully off, then on, once. If it trips again, leave it off.
- Recent events: a power outage, lightning, a hard freeze, or heavy rain before the water changed?
Quick symptom finder
| What you notice | Safe first check | Read this guide |
|---|---|---|
| Every tap is dry | Breaker and gauge | No water from your well |
| Pump runs, nothing comes out | Turn the breaker off to protect the pump | Pump running but no water |
| Pump clicks on and off fast | Watch the gauge while a tap runs | Short cycling |
| Water brown or cloudy after rain | Stop drinking it and test | Discolored well water |
| Spitting faucets | Does it happen after heavy use? | Air in the lines |
No water and pressure
- No water from your well: the first page to read when every tap goes dry.
- Well pump running but no water: why a running pump moves nothing, and why to shut it off.
- Low or fluctuating water pressure: weak showers and pressure that rises and falls.
- Short cycling or won’t shut off: a pump clicking on and off, or one that never rests.
- Pressure tank problems: waterlogged, empty or clicking tanks, and the power-off air check.
Electrical and weather
- Tripping the breaker or humming: what a trip or hum can mean, and the one reset to try.
- After a power outage or lightning: safe checks after a storm, plus general insurance notes.
- Frozen well or water line: where lines freeze first in a Wisconsin winter and safe ways to respond.
Water quality
- Brown, orange or cloudy water: when a color change after rain means stop drinking and test.
- Rotten egg, sewage or metal smells: what each smell usually points to.
- Sand or sediment: where grit comes from and why it wears out pumps.
Supply
- Air or sputtering in the lines: often a sign the water level or a pipe needs a look.
- Is your well running dry? Warning signs and the options a licensed pro may offer.
When you need a licensed professional
- The breaker trips again after one reset.
- The pump, pressure switch, control box or tank needs repair or replacement.
- Your water changed after rain or flooding, or a bacteria test came back positive.
Wisconsin rules require a DNR-licensed pump installer for pump and pressure-tank work on a drinking-water well; check with DNR if you’re unsure. Pump installers’ work ends at the pressure tank, so house plumbing and softeners need a licensed plumber.
