The Anatomy of a Backup Sump Pump System

What Is a Backup Sump Pump System?

A backup sump pump system is a secondary device designed to kick in when your primary pump fails or can’t handle the volume of water present. Depending on the unit, these systems can operate on battery power or water pressure. They continue to function during power outages, which are common during heavy storms. Sump pumps act as a safety net, ensuring your basement remains dry even when your main sump pump does not work.

The Parts of a Backup Sump Pump System

Backup sump pump systems are made up of several parts and systems for efficient operation:

Float Switch

The float is a device that detects water levels in the sump pit. When the water level rises above the inactive primary pump’s float, it will activate the backup sump pump. The float switch ensures the pump only works when necessary to help preserve power.

Check Valves

Check valves are essential parts of the backup sump pump system. They prevent the backflow of water after it has been pumped out. These valves open and allow water to flow out of the basement. When the pump turns off, the check valves close to keep the water from returning.

Electric Motor and Impeller

The electric motor and impeller are only found in battery-powered backup pumps. The motor provides the power that drives the impeller, a rotating part that forces water out of the pump.

Specialized Nozzle

Water-powered backup sump pump systems feature a specialized nozzle that creates suction to pull water out of the sump pit and push it out through the pump. As the water flows through the narrow nozzle, it speeds up and creates a pressure drop that pulls out the water.

Discharge Pipe

The discharge pipe is piping used to expel water from the sump pit. When the backup pump is activated after the main one fails, water is forced through the discharge pipe and directed away from your property. This pipe is essential in maintaining a clear path for water to exit.
