MEET THE LEAKSENTINEL SHUTOFF
Water damage is most costly when you’re not there to stop it.
That’s why the insurance industry considers automatic water shutoff valves the gold standard for preventing catastrophic water damage claims.
Unfortunately, traditional shutoff systems are prohibitively expensive. High hardware costs, invasive installation, and the need for licensed plumbers—and in many western and southern states, licensed electricians—put these solutions out of reach for many homeowners.
Enter LeakSentinel
Developed by Silicon Valley entrepreneurs, LeakSentinel represents the first major breakthrough in domestic water-shutoff technology in over 20 years. Our patented, non-invasive whole-home water-flow sensing, combined with an innovative single-sided clamp design, delivers premium protection to every home—at a fraction of the cost of plumber-installed shutoff systems.

Why Choose LeakSentinel?
Affordable & DIY-Friendly
LeakSentinel is designed for low hardware cost and simple installation. The device mounts directly over your existing shutoff valve—without cutting pipes or touching the water supply—dramatically reducing installation complexity and cost.
By eliminating the need for a licensed plumber and, in many western and southern states, a licensed electrician (where power is not available at the water entry point), homeowners save hundreds of dollars. This cost efficiency allows insurers to offer whole-home protection to their customers for under $100.
AI-Powered Whole-Home Sensing
Forget placing dozens of puddle sensors in locations water may never reach. LeakSentinel uses advanced acoustic sensing—the same principle employed by municipal water utilities—to hear water escaping anywhere in your home.
Our on-board, AI-powered algorithms detect true water flow while filtering out background noise from appliances like clothes dryers or HVAC systems, dramatically reducing false alarms.
Built for Real-World Plumbing
Most clamp-on shutoff devices only work with ball valves, yet nearly 50% of U.S. homes use gate (wheel) valves. LeakSentinel’s patented single-sided clamp securely attaches to both.
Because there is no standard for how water lines and shutoff valves enter a home—with rarely three inches of clearance on both sides of a valve—traditional clamp designs often fail in real-world installations. We engineered LeakSentinel specifically for these constraints and it is compatible with metal, PEX, and PVC piping. See real-world LeakSentinel installations below.
Always-On Reliability
LeakSentinel is powered by a six-month rechargeable lithium-ion battery, eliminating the need for nearby hardwired power—and in many western and southern states, the need for a licensed electrician. The onboard battery even protects your home during extended power outages and enables reliable outdoor installations.
Most importantly, LeakSentinel operates autonomously. When it detects a leak, it shuts off your water immediately—even if your Wi-Fi or internet connection is down.
Quick, DIY Installation
LeakSentinel is designed for homeowner installation. Setup is comparable in simplicity to installing a Wi-Fi thermostat, with no plumbing modifications or professional installation required.
