Every year, water leaks in U.S. homes cause over $10 billion in property damage — and most are discovered too late. By the time you notice a wet floor, musty smell, or skyrocketing water bill, the damage may already require thousands in repairs.
The good news? Leak detection technology has advanced dramatically in recent years. Today’s systems can identify a leak before you see a single drop, automatically shutting off your water to prevent damage.
In this guide, we’ll compare three leading options—Flo by Moen, FloLogic, and Leak Defense—so you can decide which system offers the right mix of performance, convenience, and reliability for your home.

How Each Water Leak Detection System Works
Flo by Moen
Flo by Moen is a smart, app-connected leak detection system that continuously monitors water flow, pressure, and temperature. Its AI algorithms learn your home’s normal water use patterns and can detect even minor anomalies.
Wi-Fi Required
Without an internet connection, you won’t get alerts or usage tracking.
Automatic Shut-Off
Stops water flow instantly if a leak is detected.
Mobile Insights
View usage reports, set goals, and get maintenance alerts right from your phone.
Relying on Wi-Fi for Leak Protection?
If your router or power goes down, alerts may stop. Oasis Plumbing helps homeowners decide if Wi-Fi-based systems like Flo by Moen are a good fit—or if a hardwired system is safer. Call (305) 703-8220 to choose the right leak detection system for your home.
FloLogic
FloLogic is designed for maximum reliability, even without internet access.
Ultra-Sensitive Detection
Catches leaks as small as a half-ounce per minute—ideal for hidden pinhole leaks.
Battery Backup
Continues working during power outages.
Proven Track Record
Popular in high-end and custom homes where water damage risks are costly.
Leak Defense
Leak Defense offers flexibility for both residential and commercial setups.
Multiple Valve Sizes
Works for everything from condos to estates.
Sensor Integration
Add wired or wireless leak sensors in high-risk areas for extra coverage.
Professional Installation Preferred
Best performance when installed and calibrated by a plumber.
