1. It runs all the time
A pump that runs constantly, even when it has not rained, may be undersized, have a stuck float switch, or a failed check valve that lets water flow back into the pit.
2. It never seems to run
If the pit fills but the pump does not turn on, the float switch may be stuck or the motor may have failed. Test it by slowly pouring a bucket of water into the pit; the pump should start on its own and empty it.
3. Strange noises
Grinding, rattling or loud humming can mean a worn motor, damaged impeller, or debris in the pump.
4. It cycles on and off quickly
Short cycling wears out the motor. It is often caused by a float switch set wrong or a pit that is too small for the pump.
5. Visible rust or corrosion
Rust on the pump or discharge pipe and corrosion around connections are signs of wear.
6. Its age
Many sump pumps last somewhere around seven to ten years, depending on how hard they work. If yours is older than that, or you do not know its age, it is worth having it checked.
7. No backup
Even a healthy pump stops when the power goes out, and storms often cause outages. A battery backup pump keeps water moving when the main pump cannot.
