Our Verdict
Wayne Battery Backup Sump Pump 2700 GPH — 8.8/10. A strong dedicated backup sump pump for homeowners who want automatic protection during power outages, primary pump failures, or heavy-rain events.
A battery backup sump pump is the kind of home protection you hope you never need—but when a storm knocks out power or your main sump pump fails, it can be the difference between a dry basement and a costly cleanup. The Wayne Battery Backup Sump Pump 2700 GPH is designed as a secondary pump that automatically takes over when your primary system can’t keep up.
This buying guide focuses on the Wayne Battery Backup Sump Pump 2700 GPH and whether it is the right battery backup sump pump for your basement, crawlspace, or flood-prone utility area. You’ll find the model number, ESP25, in the specs and compatibility details below.
Quick fit check
- Buy it if you already have a primary sump pump and want automatic battery backup during outages.
- Skip it as a standalone fix if your main sump pump is failing; replace or upgrade the primary pump first.
- Measure first to confirm your sump basin has room for the backup pump, float, discharge connection, and battery placement.

Wayne Battery Backup Sump Pump 2700 GPH
The Wayne Battery Backup Sump Pump 2700 GPH is built to work alongside an existing primary sump pump, adding a second layer of protection when the main pump stops operating. Its key job is simple: if the power goes out, the primary pump fails, or water rises above the backup float level, the battery-powered pump activates automatically to help move water out of the sump basin.
Although this product line is commonly described as a 2700 GPH backup sump pump, Wayne rates this backup system at up to 2,580 gallons per hour, making it well-suited for many residential basements and crawlspaces where occasional storm-driven water intrusion is a concern. It is not meant to replace a full-time primary sump pump, but it can provide important emergency pumping capacity when your main system is unavailable.
The ESP25 is especially useful for homeowners in areas with frequent thunderstorms, aging utility infrastructure, or basements that depend heavily on a sump system. The built-in alarm system is another practical feature, alerting you when the backup pump is running so you know the primary system may need attention or the home is experiencing a high-water event.
Installation is designed to be straightforward for a backup sump setup, but buyers should still verify that their sump basin has enough space for a secondary pump, float, discharge connection, and battery placement. For the best results, the Wayne ESP25 should be paired with a compatible deep-cycle battery and installed so it complements—not obstructs—the primary pump. If you are also reassessing pump sizing, our guide to choosing a sump pump by HP, material, and flow rate can help.
If your main pump is aging or undersized, compare dedicated primary options such as the Wayne 3/4 HP Submersible Cast Iron and Steel Sump Pump, the Zoeller Mighty-Mate Submersible Sump Pump 1/3 HP Cast Iron, or the Ridgid Cast Iron Submersible Sump Pump Half Horsepower before relying on a backup pump alone.

How we chose
For this buying guide, we evaluated the Wayne Battery Backup Sump Pump 2700 GPH based on the factors that matter most in a residential backup sump system: emergency pumping performance, automatic operation, installation practicality, alert features, and suitability for homes that already rely on a primary sump pump.
Because this is a dedicated guide to a single catalog product, we did not create a ranked list of unrelated models. Instead, we focused on whether the ESP25 fulfills its intended role: providing backup pumping capacity when the primary sump system is disabled by a power outage, mechanical failure, or excess water level.
We also considered the realities of ownership. A battery backup sump pump is only as reliable as its installation and battery maintenance, so we weighed features like alarm notification, compatibility with existing sump arrangements, and the importance of routine battery checks.
Final verdict: Wayne Battery Backup Sump Pump 2700 GPH
The Wayne Battery Backup Sump Pump 2700 GPH is a smart backup choice for homeowners who already have a primary sump pump and want automatic emergency protection. Its combination of battery-powered operation, up to 2,580 GPH pumping capacity, and alarm notification makes it a practical safeguard for basements in storm-prone or outage-prone areas.
Is the Wayne ESP25 a primary sump pump?
No. The Wayne ESP25 is a battery backup sump pump designed to support an existing primary sump pump. It activates when water reaches the backup float level, typically during a power outage, primary pump failure, or high-water event.
How much water can the Wayne Battery Backup Sump Pump 2700 GPH move?
The catalog rating lists up to 2,580 gallons per hour. Actual pumping performance can vary based on lift height, discharge pipe configuration, battery condition, and installation setup.
Who should buy the Wayne ESP25?
The Wayne Battery Backup Sump Pump 2700 GPH is best for homeowners with an existing sump pump who want protection during power outages or primary pump failures. It is especially useful in flood-prone areas, finished basements, and homes where water intrusion could cause expensive damage. If you are unsure whether your primary pump is properly sized, start with our sump pump sizing and flow-rate guide.
Does a battery backup sump pump need maintenance?
Yes. You should periodically test the pump, inspect the float operation, confirm the alarm works, and maintain or replace the battery according to the battery manufacturer’s guidance. A neglected battery can reduce runtime or prevent the pump from working during an outage.
Can I install the Wayne Battery Backup Sump Pump 2700 GPH myself?
Many homeowners with plumbing experience may be able to install a backup sump pump, but the setup must be done correctly to avoid float interference, discharge problems, or reduced performance.
