Battery backup for a sump pump

Backup Sump Pump Systems for Alabama Basements and Crawl Spaces

When the power goes out, your basement or crawl space shouldn’t flood.

Most sump pumps rely on electricity to operate. During major storms, the moment you need them most, they might fail. That’s why SouthernDry installs battery-powered backup sump pump systems that keep protecting your home, even when the lights go out.

Our StormCore Elite™ Fully Redundant Pumping Systems with Battery Backup gives your home a second line of defense, protecting your belongings, your structure, and your peace of mind.

Consider a Backup Sump Pump

When a Backup Sump Pump Makes the Most Sense

Not every home needs a backup system, but when the conditions are right, it can be the difference between peace of mind and disaster. Here are the most common situations where a backup sump pump is a smart addition:

Power Outages During Storms

If your home has lost power during a thunderstorm or hurricane season, your sump pump was offline when you needed it most. Backup systems keep working even when the lights go out.

Older or Overworked Sump Pumps

All pumps wear out eventually. If your primary sump pump has been running hard for years or cycling constantly during storms, a backup can be your safety net.

Flood History or High Water Table

If your home has experienced water intrusion in the past, or if you’re in a low-lying area prone to flooding, a backup pump adds another layer of security against future events.

Short Circuits or Mechanical Failures

Even a tripped breaker or faulty float switch can knock your sump pump offline. A battery backup doesn’t rely on the same electrical or mechanical systems and kicks in automatically.

Going on Vacation or Leaving for Extended Trips

When no one’s home to check on things, you want to know your basement or crawl space is protected. Backup pumps give you that assurance, even if the unexpected happens.

Finished Basements or Stored Valuables

If your basement has carpet, drywall, electronics, furniture, or anything valuable, flood prevention becomes non-negotiable. A backup system protects your investment.

Crawl Spaces with HVAC or Mechanical Equipment

In homes where HVAC systems, furnaces, or water heaters are located in the crawl space, keeping that space dry is critical. A backup pump helps avoid costly damage and dangerous conditions.

How It Works

How Our StormCore Elite™ Fully Redundant Pumping Systems with Battery Backup Work

SouthernDry installs powerful, fully integrated battery backup systems that activate automatically if your main sump pump loses power or fails.

Here’s what you can expect:

  1. Secondary pump unit: Installed alongside your primary sump pump, ready to activate when needed.
  2. Deep-cycle marine battery: Designed for long standby periods and immediate high-power performance during outages.
  3. Automatic switching: If the primary pump fails or the power goes out, the battery backup takes over instantly.
  4. Performance monitoring: Many systems include an easy-to-read screen or alert system to monitor battery charge, pump performance, and runtime status.
  5. High water handling capacity: Capable of pumping thousands of gallons per hour, enough to manage even major downpours.

Southern Dry was not the cheapest but no where near the most expensive.

My crawlspace was wet, moldy, and just nasty. The insulation was soaking wet and it smelled awful. I called five different companies to come out and give me quotes on what they thought needed to be done. I had quotes all over the board ranging from $7,000 all the way up to $48,000. Southern dry…
