There are two main types of sump pumps: pedestal and submersible. Pedestal sump pumps have the motor above the sump pit and are typically less expensive, but are also louder and less durable than submersible pumps. Submersible sump pumps are completely submerged in the sump pit, which makes them quieter and more durable.
The lifespan of a sump pump can vary, but on average, sump pumps last between 5-10 years. It's recommended to have a professional check your sump pump every year.
A sump pump is a device that pumps water that has accumulated in a sump basin, typically located in the basement of a home, to prevent flooding. The pump is activated by a float switch that senses when water levels in the basin have risen to a certain point, and turns on to pump the water out to a drain or discharge point.
