Performance: 5/5 
DROP offers every method of leak detection. The valve's built-in flow meter monitors for continuous flow and leaky toilets, while the proactive Slow Leak Test pressure-checks the system for pinhole leaks overnight. The included Leak Detectors provide instant, spot-on detection at high-risk areas (like water heaters), triggering an immediate water shutoff. Crucially, this shutoff function works using the proprietary DROPLink network, meaning it operates even if your home internet is down.
User Experience: 4/5 
Installation, like all whole-house shutoff valves, requires a professional, which is an added cost. The valve can be oriented in a few directions allowing for ease of installation. The Hub and Leak Detectors are easy to set up and place. The included battery backup ensures the system stays online during power outages. The mobile app provides necessary monitoring and remote control, I personally think the app needs some polishing, but once you learn it and know where to looks it is solid overall. You can also add a ton of Leak Detectors, up to 32, to get under every sink and area of your house you are concerned about.
Quality: 5/5
The quality is awesome, earning a perfect score. The 5-Year Limited Warranty on the Valve and Hub is included, not an extra cost, demonstrating a commitment to long-term reliability that is unmatched in this category. The components are built with durable materials, and the fact that the crucial leak-detection-to-shutoff sequence works via its dedicated DROPLink signal provides superior functional quality over Wi-Fi-dependent systems.
Value: 4.5/5 
While the upfront cost for the kit plus professional installation is high, the D-HPS-K1 kit offers the best out-of-the-box value. It includes the Valve, the Hub, two leak detectors, and 9V battery backup, accessories often sold separately by competitors. The included 5-year warranty eliminates the need for expensive subscriptions, resulting in a significantly lower Total Cost of Ownership (TCO) compared to alternative premium systems. You pay for peace of mind, and DROP delivers the most comprehensive package for that price.
Final Verdict
The DROP Leak Detector System (D-HPS-K1) is the ultimate choice for homeowners seeking resilient, no-compromise water damage prevention. Its offline functionality, dual-detection methods, and industry-leading warranty make it the best long-term security blanket for your home's plumbing. While the initial investment requires a qualified plumber, the long-term savings in insurance discounts, avoided water bills, and—most importantly—prevented water damage, make this system highly recommended.
Pro Tip: Place one of the included Leak Detectors with the optional sensing cable next to your water heater or washing machine first. These are two of the highest-risk appliances for catastrophic failures.

DROP Leak Detector System FAQ
What does the DROP Hub do?
The DROP Leak Detector Hub is the central controller for the DROP water system. It manages system connectivity and coordination so all connected components can function within a single, unified network.
What happens if the power goes out?
A built-in backup power source keeps the Hub running during short outages so core communication between devices can continue without interruption.
Can the system still work during an internet outage?
Even without internet, the Hub can still manage local communication between connected DROP devices, which allows basic system functions and automated responses to keep operating.
What do DROP Leak Detectors do?
Continuously monitor areas where water leaks are most likely to occur, such as under sinks, near water heaters, washing machines, and appliances. When water or abnormal temperature conditions are detected, the system sends real-time alerts to help homeowners respond quickly and prevent water damage.
How do DROP Leak Detectors detect leaks?
Each unit uses highly sensitive moisture sensors to identify the presence of water at the exact installation point. This allows the system to detect everything from small drips and appliance failures to larger flooding events as soon as they occur.
What does the DROP Home Protection Valve do?
The DROP Valve continuously monitors water flow and pressure throughout your home. If it detects unusual water usage, a leak, or continuous flow, it can automatically shut off the water supply to help prevent costly water damage.
How does the DROP Valve detect leaks?
Built-in flow meters and pressure sensors analyze water usage patterns in real time. The system can identify issues such as running toilets, dripping faucets, burst pipes, and other abnormal water flow conditions before they become major problems.
