Most likely causes
Float switch failure
Floats can stick against the pit wall or fail internally.
Failed check valve
Water flows back into the pit after each cycle, causing short cycling.
Clogged intake
Debris, gravel or silt block the pump screen.
Discharge problems
Frozen, crushed or disconnected discharge lines stop water leaving the house.
Power outages
Storms that drive water in often knock out power at the same time.
Undersized or worn pump
Pumps wear out, and some are undersized for the water volume.
How the problem is diagnosed
- Pour water into the pit to trigger the float
- Check the outlet and breaker
- Listen for the check valve closing
- Inspect discharge outdoors

Specific sump pump repair services
Sump Pump Repair: common questions
How do I test my sump pump?
Slowly pour a bucket of water into the pit until the float rises. The pump should start, empty the pit and shut off. If it does not, check power and the float switch.
Why does my sump pump run constantly?
A stuck float, a failed check valve, an undersized pump, or a high water table can keep it running. Constant running wears the motor quickly.
How long do sump pumps last?
Many last roughly 7 to 10 years, depending on how often they run and the pump quality.
Do I need a battery backup sump pump?
If your basement relies on the pump during storms, a backup is worth considering because storms often cause power outages.
Where should a sump pump discharge?
Away from the foundation, to a location where water will not flow back toward the house. Many municipalities prohibit discharging into the sanitary sewer.
