On average, a sump pump lasts for about 10 years. However, with proper maintenance and regular inspections, you may be able to get a few more years.
The unfortunate reality is that no matter how well you take care of your sump pump, eventually, it will need to be replaced.
To determine whether your sump pump needs to be replaced or repaired requires troubleshooting for all possible problems. This means ensuring that power is running to the sump pump, there are no clogs, the discharge pipe hasn’t frozen, the basin is installed correctly, and that the switches and valves are operating correctly.
While you can check for some of these problems pretty easily, others require a full inspection by a professional plumber. They will be able to tell you if your sump pump is repairable or if it needs to be replaced.
