The average life expectancy is 5 to 7 years for a residential sewage pump and 5 to 15 years for a commercial sewage pump. Life expectancy of the pump depends on many different factors, some of which are the quality of the pump, how often the pump has to run, and the electrical supply to the pump.
The table below lists common troubleshooting symptoms, probable causes, and corrective actions.

Pump won't start or run | Blown fuse | Replace with proper size fuse |
Defective float switch | Replace the float switch. |
