Why a Leak Can Cost You Thousands
A leaking pipe might seem like a small problem—until it’s not.
One broken hose can flood your basement. One slow drip behind a wall can grow mold in weeks.
Automatic water shut off valves don’t just sound alarms. They take action—automatically, even when you're asleep or on vacation.
With Grus, you can go beyond detection. Our smart water protection system is designed to sense, alert, and shut down leaks before they become disasters.
> Because water waits for no one—and insurance won’t always cover the loss.
Effortless control for a sustainable, cost-effective home
One System. Total Protection.
From your hose to your water main, Grus has it covered.
The Grus AquaNet Smart Water Protection System combines five powerful devices—including smart valves, leak sensors, and hose timers—that form a flexible and automated defense.
- Main Function:
Monitor valve status and flow on existing manual shutoff valves

Ideal for older homes or condos where the main valve can’t be replaced
- Unique Feature:
Works with legacy plumbing—get smart alerts without replacing your valve
- Main Function:
Automatically cuts off water supply when triggered
- Scenario:
Main water line shutoff for whole-house protection
- Unique Feature:
Motorized actuator + real-time water flow and pressure tracking
- Main Function:
Continuous cable sensing for full-area water leak detection
- Scenario:
Water heaters, toilets, behind fridges
- Unique Feature:
Compact, battery-powered, app alerts when leak is detected
- Main Function:
Senses pooling water through dual electrodes with high precision
- Scenario:
Basement, laundry room, under sinks—anywhere water might collect
- Unique Feature:
Sends instant alerts and can trigger shutoff when paired with BD or VM
- Main Function:
Controls outdoor faucets with app-based or timed watering
- Scenario:
Gardens, lawns, patio faucets
- Unique Feature:
Solar-powered with rain delay + soil sensor compatibility

Real-World Scenarios: Leak Detection in Action
Every drop matters. Every corner protected.
Scenario 1
You're away on a business trip—and a pipe bursts.
The AquaNet-M immersion sensor detects pooling water on the floor. It sends a signal to AquaNet-BD, which closes your existing shutoff valve automatically.
Scenario 2
You forgot to turn off the backyard faucet—again.
With the AquaNet-HT smart hose timer, you can schedule irrigation remotely and avoid overwatering. Even better? Its rain delay and soil sensor options mean no wasted water during wet weather.
Scenario 3
Basement water heater leaks overnight.
AquaNet-LD sensor catches the leak and sends a command to the AquaNet-VM shutoff valve. The motorized valve cuts water supply instantly—even while you’re asleep.

Why Our Smart Water Shutoff Valve Stands Out
A complete smart valve—built for modern homes.
AquaNet-BD isn’t just a valve.
It’s a full-featured automatic water shut off valve designed for smart homes.
It replaces your manual main valve with a motorized shutoff that connects directly to WiFi.
You’ll get instant alerts, flow rate data, remote control, and more—right from your phone.
Key Features:
- Real-time flow monitoring (0.1 gal/min accuracy)
- Settable high/low flow alarms
- WiFi + Tuya Smart Life compatibility
- Optional backup battery
- Install with standard DN20 (¾") fittings
Ideal for:
- Homes upgrading to smart protection
- DIY installs (no hub, no subscription)
- Whole-home leak response when combined with sensors
Questions About Smart Water Valves and Leak Detection?
1. Do smart water shutoff valves really work?
Yes—when properly installed, a smart water shutoff valve like the AquaNet-BD can monitor flow and instantly shut off your main water supply. It can also pair with leak detectors for automatic response, giving you real-time alerts and full control via your phone.
Curious how it installs?
2. What's the difference between AquaNet-BD and AquaNet-VM?
Both are full-featured smart water shutoff valves, but AquaNet-VM goes one step further.
AquaNet-VM includes built-in temperature, pressure, and flow sensors, making it ideal for users who want detailed system diagnostics and environmental protection alerts.
AquaNet-BD focuses on core shutoff functionality and flow monitoring, with simpler installation and backup battery support.
> AquaNet-VM is for high-sensitivity monitoring; AquaNet-BD is for affordable, reliable protection.
3. Can I link leak detectors to shut off the water automatically?
Yes. Devices like AquaNet-M (immersion) and AquaNet-LD (cable sensing) can be linked with AquaNet-BD or VM. When a leak is detected, the valve can close automatically—creating a full leak detection system for home use.
4. Will it still work if the power goes out?
Yes. AquaNet-BD supports a backup battery (Ni-MH), which ensures the valve can still respond during power outages. During blackout mode, remote app control is paused, but local valve operation still works.
5. Do I need a hub or subscription to use it?
No hub. No monthly fees.
All Grus AquaNet devices work on your 2.4GHz WiFi and are controlled via the Tuya Smart Life app—the same app used by millions of smart home users worldwide.
6. How much does it cost to install a water leak system?
It depends on how many areas you want to protect.
A basic setup with one automatic water shut off valve and a leak detector starts under $200.
Expanding to cover multiple rooms with cable sensors or hose valves can cost $300–$500—still far less than a single flood repair.
7. Is a water shut off valve worth it for Airbnb or rentals?
Absolutely. An automatic water shut off valve paired with leak detectors can prevent major flood damage when no one’s home.
It’s the best protection for remote properties, rentals, or short-term listings.
