Battery Backup Sump Pump in Columbus, Ohio

Transit & Flow Group installs battery backup sump pumps for Columbus-area homeowners whose primary pump is fine but whose power isn’t guaranteed to be. A battery backup is a second, independent pump added to your existing pit that runs on a charged battery when the outlet feeding your primary pump goes dead, which is exactly when storms most often knock out electricity in Central Ohio. Describe your current setup in the Estimate Builder for a preliminary online estimate.

Is this the right service for you?

A battery backup add-on fits a homeowner who already has a working primary pump and wants protection against power loss specifically, not a full system replacement. Common situations:

• You have a finished basement where even a short flood during a power outage means real damage to flooring, drywall, or stored belongings.
• Your basement has flooded before during a storm that also knocked out power, and you do not want a repeat.
• You have a high water table or heavy inflow during storms, where losing pumping capacity for even an hour matters.
• You travel or are away from home often and want protection running even when nobody is there to notice a problem.
• You already have a sound primary pump and specifically want the backup added, rather than a bundled combination system built around both from the start.

If you do not yet have a working primary pump at all, either because it has failed or because your basement has never had a sump system, start with Sump Pump Replacement or New Sump Pump Installation first; a battery backup is an addition to an existing, functioning primary pump, not a replacement for one. And if you want the primary pump and the battery backup selected, sized, and installed together as one coordinated system from the outset, rather than adding a backup to a pump you already have, our Combination Sump System service bundles both into a single job.

How pricing works

Battery backup installation is scope-based pricing, built around your existing pit and pump. The logic:

• The backup pump and battery unit is priced by capacity and battery type; deep-cycle batteries and higher-capacity backup pumps run higher than standard alternatives.
• Installation into your existing pit covers mounting the backup pump alongside your primary unit, tying into the discharge line, and wiring the battery charging system.
• What changes the price: pit size and whether it comfortably fits a second pump, battery size and expected run time, and whether a dedicated charging circuit is needed.
• Water-powered backups exist as an alternative to battery systems, running on household water pressure instead of a battery, with no battery to replace over time, though they require municipal water service and will not work on a well. We can discuss whether that alternative fits your situation, though the system detailed on this page is the battery-powered version.

As general market context, not a Transit & Flow quote, Angi’s 2026 data puts average battery backup sump pump installation between $600 and $1,200, averaging around $900, with a fuller range of roughly $300 to $1,800 depending on battery size and pump capacity.

Central Ohio context

Central Ohio’s hardest rain events tend to arrive with the storm systems most likely to knock out power in the first place, which is exactly the moment a primary pump’s protection stops mattering if the outlet feeding it has gone dead. Clay soil compounds the risk: heavy rain saturates the ground around a foundation and keeps feeding water toward the pit for days, meaning an outage during or right after a big storm can span the exact window when the most water is trying to get in.

Freeze-thaw winters are a secondary factor worth naming. Ice storms are a common cause of power loss in Central Ohio, and an ice storm arriving on top of already-saturated ground from a late-winter thaw is a realistic scenario for basements across the area, not a rare edge case.

Our process

1. Describe your current setup online. Primary pump condition, pit size, and basement finish level go into the Estimate Builder for a preliminary online estimate.
2. Book the visit. Same-day availability may be available depending on location and schedule.
3. Assess pit fit. We confirm your pit can accommodate a second pump and battery unit, and identify the best charging circuit setup.
4. Install and wire. Backup pump mounted, discharge tied in, battery installed and charging.
5. Simulated outage test. We power off the primary pump and run the backup through full cycles while you watch, then walk the discharge line to confirm it clears water on battery power alone.
