How submersible, pedestal, battery backup and water-powered pumps differ in noise, life, cost to run and what happens in an outage.
A sump pump lifts water out of a pit and sends it outside. The common types are submersible pumps, which sit in the water, and pedestal pumps, which sit above the pit on a stem. Battery backup pumps take over when the power fails, and some homes use a water-powered backup that runs on pressure from the water line. Each has strengths and trade-offs, and the best choice depends on the pit, the inflow and how much you worry about outages.
Submersible pumps run quietly and handle heavy use, while pedestal pumps are easier to service but louder and take up more room. Battery backups are valuable around Nashville, where storms can knock out power just as the pit fills. Water-powered pumps need no battery but use municipal water and depend on adequate pressure. We explain the options with your pit and your discharge in mind.
Sits in the pit, runs quietly and is cooled by the water around it.
Motor sits above the pit, which is easier to reach but louder.
Runs from a battery when power fails or the main pump cannot keep up.
Uses water pressure to run and needs no electricity.
Pit size, lift height and inflow decide the pump you need.
Alarms and switches warn you when something goes wrong.
