Battery Backup Sump Pump Systems

No More Flooding Anxiety During Storms

You know that sinking feeling when the power goes out during a heavy storm. Your sump pump stops working right when you need it most. Water starts creeping into your basement, threatening your finished space, your belongings, everything you’ve invested in down there.

A properly installed battery backup sump pump eliminates that worry completely. When your main pump loses power, the backup system kicks in automatically. No scrambling for generators, no panic calls to emergency services, no watching water slowly destroy your basement.

Your finished basement stays dry. Your stored belongings stay safe. You sleep through storms knowing your backup system is handling whatever nature throws at it. That peace of mind is worth every penny, especially when you consider that basement flood damage typically costs $10,000 or more to repair.

Des Plaines Sump Pump Specialists

We Know Chicago-Area Basements Inside Out

We’ve been protecting Des Plaines basements for years. We understand how quickly our area’s heavy rains can overwhelm drainage systems, especially when they coincide with power outages.

We’ve seen too many homeowners learn the hard way that their sump pump only works when the power’s on. That’s why we focus specifically on battery backup systems that actually work when you need them most.

Our team knows which backup systems hold up to Chicago’s weather patterns and which ones fail when it matters. We install systems that last, not the cheapest options that leave you vulnerable.

Sump Pump Backup Installation Process

Simple Installation, Reliable Protection

We start by evaluating your current sump pump setup and basement layout. Every installation is different, and we need to understand your specific drainage patterns and power requirements before recommending a system.

Next, we install the battery backup pump alongside your existing primary pump. The backup system connects to a deep-cycle marine battery that’s specifically designed for this type of emergency use. We position everything for optimal performance and easy maintenance access.

The system includes an automatic float switch that activates the backup pump when water levels rise and your primary pump isn’t running. We test everything thoroughly before we leave, including simulating power outage conditions. You’ll see exactly how the system responds when your main pump stops working.

We also show you the simple maintenance routine and explain how to monitor battery health. The whole installation typically takes a few hours, and you’re protected immediately.

Best Battery Backup Sump Pumps

Quality Components That Actually Work

We only install battery backup systems that we’d put in our own basements. That means marine-grade deep-cycle batteries that can handle repeated charging cycles, not car batteries that fail after a few uses.

The backup pumps we install are specifically designed for emergency use. They’re built to handle continuous operation during extended power outages, not just brief backup periods. We’re talking about pumps that can run for hours if needed, moving thousands of gallons of water on battery power alone.

Every system includes a control panel that monitors both your primary pump and backup system. You’ll know immediately if there’s a problem with either pump, the battery charge level, or any other component. No surprises during the next big storm.

We also include a high-water alarm that alerts you if water levels get too high for any reason. It’s an extra layer of protection that gives you time to respond if something unexpected happens.

The kit includes a green sump pump, a black battery box, a battery backup system, and various fittings, cables, clamps, and connectors. The components are organized neatly to showcase all parts included for installation or replacement, highlighting the comprehensive nature of the kit for flood prevention and basement water management.
A properly sized battery backup system typically runs 5-7 hours of continuous pumping, or up to 24 hours with intermittent use. The actual runtime depends on how much water the pump needs to move and the battery’s condition. We size the battery based on your specific basement’s water flow patterns and your primary pump’s typical workload. Most power outages don’t require continuous pumping, so you’re usually looking at much longer protection periods than the continuous runtime numbers suggest.
While some homeowners attempt DIY installation, we strongly recommend professional installation for reliability reasons. The backup system needs to be properly integrated with your existing pump, and the float switches must be positioned precisely to avoid conflicts. Electrical connections need to meet local codes, and the system requires testing under simulated failure conditions. A mistake in installation often isn’t discovered until you actually need the backup system, which is exactly when you can’t afford for it not to work.
Deep-cycle marine batteries are the gold standard for sump pump backup systems. These batteries are designed for repeated deep discharge and recharge cycles, unlike car batteries that fail quickly in this application. We typically recommend AGM (Absorbed Glass Mat) batteries because they’re maintenance-free, won’t leak acid, and perform better in basement temperature variations. A quality marine battery will last 3-5 years with proper maintenance, while a car battery might fail after just a few discharge cycles.
Modern backup systems include control panels with indicator lights showing battery charge level, pump status, and system health. We recommend testing your system monthly by unplugging your primary pump and ensuring the backup activates automatically. You should also check the battery voltage quarterly and inspect the system for any obvious issues. The high-water alarm should also be tested periodically. We provide a simple maintenance checklist with every installation that takes just a few minutes each month.
Yes, because generators don’t start instantly and may not start at all during critical moments. Sump pumps need immediate power when water levels rise, and even a few minutes without pumping can lead to basement flooding. Generators also require fuel, maintenance, and manual startup in many cases. A battery backup system provides instant, automatic protection that doesn’t depend on fuel availability or mechanical starting systems. Think of it as your first line of defense, with the generator as additional backup for extended outages.
This is why we install high-water alarms with every backup system. If both pumps fail, the alarm alerts you immediately so you can take emergency action. We also recommend annual maintenance to prevent dual failures, which are usually caused by clogged discharge lines, failed check valves, or other preventable issues. Some homeowners in high-risk areas choose to install dual battery backup systems or add a water-powered backup pump as a third layer of protection. We can assess your specific risk level and recommend the appropriate level of redundancy for your situation.
