POWERFUL FEATURES

Everything You Need. All in One Kit.

Active Defense: A Complete Safety Loop

Instant Sensor-to-Valve Response:

Unlike basic alarms that only notify you, our system takes action. Once a leak is detected, the main valve shuts off in just 12 seconds, stopping a "flood" before it starts.

 

Local Automation (Offline Protection):

Reliability is key. Even if your Wi-Fi goes down, the Zigbee-based connection between your sensors and the alarm remains active. This ensures your home stays protected 24/7, with the alarm ready to alert you instantly—whether you are online or offline.

 

90dB Piercing Siren:

The 90dB alarm (as loud as a power drill) works with instant App push notifications to ensure you're alerted immediately, whether you’re sound asleep or miles away from home.

Advanced Monitoring: Professional-Grade Water Intelligence

Real-Time PSI Tracking:

The valve features a built-in pressure sensor with a 0–200 PSI range. This helps homeowners monitor Pressure Reducing Valve (PRV) failures, preventing pipe bursts caused by high-pressure stress.

 

High-Precision Leak Detection (0.1 Gal):

With a flow accuracy of 0.1 gallons, our "One-Click Test" can identify microscopic "pin-hole leaks" hidden inside walls that standard sensors would miss.

 

Freeze & Scald Alerts:

Real-time temperature monitoring (accurate to ±0.9°F) provides critical warnings before pipes freeze in winter—a life-saving feature for homes in the Northern US.

 

Comprehensive Data Dashboard:

View your pressure, flow rate, and temperature in one live feed, turning your "invisible" plumbing into a transparent digital asset.

Industrial-Grade Reliability & Durability

Hardwired Ethernet Gateway:

Our gateway supports an RJ45 Ethernet connection. Unlike Wi-Fi-only hubs, it bypasses signal interference and thick walls, providing the most stable communication foundation possible.

 

IP67 Waterproof Sensors:

 Fully sealed and submersible. These sensors continue to function even when underwater, ensuring the signal is sent before the device is compromised.

 

Dual-Power Redundancy:

 The siren supports Type-C continuous power plus dual CR123A backup batteries. Your defense system stays live even if a hurricane or storm knocks out your power.

 

Ultra-Low Power Consumption:

 Using Zigbee 3.0, the sensors' CR2032 batteries last 1–2 years, providing long-term protection with zero maintenance hassle.

User-Centric Design: Flexible & Discreet

Seamless Bluetooth 5.0 Setup:

The valve features Bluetooth 5.0 for "Instant-Pairing." The App auto-discovers devices for a frustration-free, 5-minute DIY installation.

 

Discreet Deployment:

 At just 1.97" x 1.97" x 0.7", these sensors are incredibly compact. They hide easily under dishwashers, behind laundry machines, or inside tight water heater pans.

 

Universal Pipe Compatibility:

The valve comes in 3/4" and 1" (DN20/DN25) sizes, fitting the standard main water lines found in nearly all American residential homes.

 

All-Weather Performance:

 Engineered to operate from 14°F to 140°F, ensuring total reliability in sweltering attics, damp basements, or freezing garages.

ROI & Real Financial Value

Home Insurance Discounts:

This "Active Shut-off" system is highly recognized by major US insurers (like State Farm or Allstate). Installation can qualify you for 5%–15% premium discounts, effectively paying for itself.

 

Increased Home Value:

In the US real estate market, a pre-installed smart water defense system boosts your "Smart Home" rating and increases appeal to tech-savvy buyers.

 

Zero-Tolerance for Mold:

Avoid the nightmare of "Mold Remediation," which can cost $10,000+. By stopping leaks instantly, you protect your home's wooden structure and your family's respiratory health.

I received this detector on 1/4/2026. And today, it saved my house. This water leak detector is absolutely worth having if you have a sump pump. The app alerted me before 6 a.m. this morning, right when the leak was just starting. Without that early warning, I wouldn’t have noticed the issue until much later, and it could have turned into a much bigger problem. The alert was instant and clear, double alerts, from the smartphone app and wifi connected base. If you rely on a sump pump or have a basement where water issues are a concern, this is a must-have. 🙏 #CarroHome #LifeSaver #CarroHome

We had a repeat water leak during a storm tonight and thanks to having gotten these water detectors, we heard it alarm immediately and had much less water to have to clean up. Govee connected devices are really reliable and easy to use. #SmartHome #DIY #SmartLife

I have had wooden floors in my home for the last 12 years and I have had more than my share of damage to wooden flooring from water, leaks, accidental, overflows, sinks, etc. This was a great product for placing anywhere that you could have a potential leak or have had one in the past. I have mine one behind each toilet, one near the dishwasher, one near the washing machine, one under the sink. The funny part is, and I appreciated this they sent me twice as many as I ordered! Great product as soon as there’s darkness on the floor, it connects the circuitry which then sends off a pretty decent volume alarm. Not quite as loud as a fire detector, but definitely audible within a couple of rooms or within the household. 👏 #Automation

Frequently Asked Questions

Absolutely not. One of our core principles is "Zero Hidden Costs." Once you purchase the kit, you own the hardware and the protection for life. There are no monthly fees to access your device, receive alerts, or use the automation features.

Your home stays protected. Because our kit uses Zigbee 3.0 technology, the sensors, alarms, and smart plugs talk directly to the Gateway on a local mesh network. Even if your Wi-Fi is disconnected, the local automation (e.g., a leak triggering the alarm and cutting power via the Smart Plug) will still function.

The Smart Plugs act as your "Active Enforcers." You can plug high-risk appliances like washing machines or dehumidifiers into them. Through the App, you can set a rule: "If Water Sensor A detects a leak, turn off Smart Plug B immediately." This prevents electrical hazards and stops the appliance from potentially pumping more water into the flood.

Yes. We do the hard work for you at the factory. Every device in your 10-piece kit arrives pre-paired to your Gateway. You don't have to manually sync 10 different devices; just power them up, and they will automatically appear in your App, ready to work.

Our sensors are designed for extreme energy efficiency. Under normal conditions, the pre-installed batteries last up to 2 years. You will receive a low-battery notification on your phone well in advance, so you're never left unprotected.
