Basement Defender is Always
Monitoring

A homeowner can’t hire a personal sump pump technician to monitor their system daily and warn of issues. The Basement Defender sump pump monitor replaces this need, protecting your home 24/7.

This Wi-Fi-enabled system is a complete sump pump monitoring and alarm solution. Once daily, Basement Defender activates your primary sump pump and battery backup to ensure they’re working properly.

During testing, it checks the entire system—including float switches, battery chargers, and environmental factors like temperature and humidity. Test results are sent directly to your phone or email, immediately alerting you to any issues.

With proactive daily testing, Basement Defender helps prevent water damage and flooding, giving homeowners peace of mind.

Why Do I Need Sump Pump Monitoring?

A sump pump prevents water damage by managing water levels around your home. If it fails, your home becomes vulnerable to flooding. Many homeowners assume insurance will cover the damage, but most standard policies exclude flood damage, leaving homeowners to cover costly repairs. Even with flood insurance, coverage often falls short of full repair expenses.

Basement Defender proactively detects and reports battery and sump pump issues before they lead to failure. Investing in this system can save you thousands by continuously monitoring your sump pump, protecting your home, and providing early warnings of potential emergencies.

 Trustindex verifies that the original source of the review is Google. Saturday the wifi on my basement defender went offline.  I followed all the steps to reconnect to no avail.  I called Josh on Monday, and he walked me through reconnecting,  including unstalling the app & reinstall.  He was very patient. Josh was awesome! The Wifi is reconnected.  I'm very grateful to Josh. Thank you.
