Battery Backup Sump Pump in Northwest Indiana

The heaviest storms also cause the most power outages — exactly when you need your sump pump most. A battery backup system keeps your basement protected even when the power is out. Downing Plumbing installs backup sump pump systems throughout Northwest Indiana.

BATTERY BACKUP SUMP PUMP

The Storm Takes Your Power — Then What?

Heavy thunderstorms in Northwest Indiana frequently knock out power — and those same storms are driving the most water into your sump pit. Without a backup system, a power outage during a major rain event means your primary pump is dead while water rises in the pit. Basement flooding can begin in minutes in high water table areas like Merrillville, Crown Point, Portage, and Hobart.

A battery backup sump pump sits above your primary pump in the pit. When the primary pump fails — either from power loss, motor failure, or being overwhelmed by high water volume — the backup activates automatically and pumps water using a sealed lead-acid or AGM battery. Quality backup systems can pump 1,000–2,000+ gallons per hour on battery power, providing hours of protection during an extended outage.

Battery backup systems also protect against primary pump mechanical failure — if your primary motor burns out during a storm, the backup keeps the basement dry until you can get it repaired or replaced. Downing Plumbing installs combination primary/backup units or standalone backup systems that work alongside your existing pump — whichever configuration fits your pit and budget.

Installing a Battery Backup Sump Pump

We assess your existing system and add backup protection that works automatically — no action needed when the power goes out.

1

Evaluate Your Current System

We assess the pit size, primary pump position, and discharge configuration to determine the best backup pump type and placement.

2

Install the Backup Pump

We position the backup pump above the primary in the pit, set the float to activate at a higher water level than the primary, and connect it to the discharge line.

3

Wire the Charger and Controller

We wire the battery charger to a nearby outlet, connect it to the battery, and configure the controller that monitors both the primary pump and backup battery status.

4

Test Under Power-Out Conditions

We simulate a power outage by unplugging the primary and raising the float to verify the backup activates automatically and pumps at rated capacity.
