Why Is My Sump Pump Running Continuously? Causes, Fixes & When to Call a Pro
A sump pump running constantly — or a sump pump that won't turn off — is your system waving a red flag. Left alone, a non-stop pump burns out its motor and can still let your basement flood. Here's why it happens, how to troubleshoot it yourself, and when to call for sump pump repair in Cathedral City, CA.
Is It Normal for a Sump Pump to Run All the Time?
Short answer: no. A healthy pump cycles on when water rises and shuts off when the pit is clear. If yours runs non-stop — or kicks on every few seconds — something is wrong. Even during wet weather, constant operation means the system can't keep up or can't shut itself down properly.
5 Reasons Your Sump Pump Keeps Running
- Stuck float switch. The float tells the pump when to run. If it's tangled, jammed, or waterlogged, the pump never gets the "off" signal — the most common cause we see.
- Clogged or blocked discharge line. If water can't exit the pipe, the pump runs forever trying to empty a pit that never drains.
- Failed check valve. This one-way valve stops discharged water from flowing back into the pit. When it fails, the same water loops endlessly and the pump never rests.
- Undersized pump. A pump too small for your water inflow runs continuously and still falls behind — a common issue in homes with a high water table.
- Excessive groundwater or heavy rain. Sometimes the pump is fine and there's simply more water than usual. But if it never catches up, you likely need a larger pump or a second unit.
How to Troubleshoot a Sump Pump That Won't Stop Running
- Check the float switch: lift it by hand — if the pump stops, the switch was stuck. Clear any debris so it moves freely.
- Inspect the discharge line: look for kinks, clogs, or blockages at the exit point outside your home.
- Listen to the check valve: a solid clunk when the pump stops is normal. Silence, plus water flowing back, means the valve has failed.
- Watch one full cycle: if the pit refills within seconds of pumping out, suspect a failed check valve or rising groundwater.
Warning Signs You Shouldn't Ignore
- Grinding or rattling noises from the pump
- A burning smell near the unit
- Water stains or dampness on basement walls
- The pump runs but the water level never drops
