Smart Home Water Protection System

The Complete Guide for 2025


Water damage is one of the most expensive and stressful problems homeowners face.

A small leak under a kitchen sink, a failed dishwasher hose, or a frozen pipe can cause thousands of dollars in damage—often before anyone notices.

That’s why more homeowners are switching from basic leak alarms tosmart water protection systemsthat candetect leaks, alert you instantly, and automatically shut off water before damage spreads.

This page helps you decide whether a smart water protection system is right for your home—and how to choose the right setup in 2025.

Why Water Protection Matters for Every Home

Even a small leak can cause big problems. Most water incidents fall into three categories:

Slow leaks

Hidden drips under the sink, behind appliances, or along plumbing joints. These often go unnoticed for weeks.

Overflow or appliance failure

Dishwashers, washing machines, or refrigerators with water lines can fail suddenly.

Burst pipes

Common in winter—especially in basements, exterior walls, or vacation homes.

Average repair cost in North America:

  • Minor cabinet repairs:$500–$1,500
  • Flooring replacement:$2,000–$8,000
  • Full kitchen rebuild after long-term leak:$10,000+


Most homeowners don’t realize:

Insurance claims for water damage now exceed fire and theft combined.

Common Household Leak Scenarios

To truly protect your home, you need to address the areas where leaks most commonly occur.

{{brizy_dc_image_alt imageSrc=
Kitchen Sink & Dishwasher Leaks
  • Loose drain fittings
  • Failed dishwasher hose
  • Leaks only when the dishwasher runs
  • Cabinet swelling without visible water
{{brizy_dc_image_alt imageSrc=
Bathroom Leaks
  • Toilet base seepage
  • Shower supply line leaks
  • Loose angle stop valves
  • Hidden moisture beneath tile
Outdoor & Irrigation Leaks
  • Water heater tank leaks
  • Main line corrosion
  • Burst pipes during freeze events

Basement leaks spread quietly and are costly because water pools unnoticed.

{{brizy_dc_image_alt imageSrc=
Basement & Utility Leaks
  • Water heater tank leaks
  • Main line corrosion
  • Burst pipes during freeze events

Basement leaks spread quietly and are costly because water pools unnoticed.

{{brizy_dc_image_alt imageSrc=
Laundry Room Leaks
  • Washing machine hose rupture
  • Drain overflow
  • Old rubber hoses cracking under pressure

A burst washing machine hose can release500+ gallonsper hour.

How a Smart Water Protection System Works

A modern system combinesthree layers of protection:

{{brizy_dc_image_alt imageSrc=
{{brizy_dc_image_alt imageSrc=

Leak detection sensors


Sensors placed under sinks, behind appliances, and near water heaters detect moisture the moment it appears and send instant alerts.

{{brizy_dc_image_alt imageSrc=

Flow-based monitoring


Flow monitoring identifies abnormal water usage, continuous flow, and hidden leaks behind walls that sensors alone can’t detect.

{{brizy_dc_image_alt imageSrc=

Automatic water shut-off valve


When a leak is detected, the system can automatically shut off your main water supply—even if you’re away from home.

Together, these layers protect against bothsmall leaksandcatastrophic pipe failures.

Which Water Protection System Is Right for You?

Use this quick guide to choose the right setup:

Most homeowners choosewhole-home systems, because water damage rarely follows a single-room pattern.

{{brizy_dc_image_alt imageSrc=

Concerned about small leaks (kitchen, bathroom)

→ Leak sensors with mobile alerts

Want leaks to stop automatically

→ Leak sensors + automatic shut-off valve

Whole-home protection

→ Sensors + rope sensors + automatic shut-off valve

Vacation home or winter freeze risk

→ Full system with automation and remote control

Insurance-focused protection

→ Automatic shut-off valve with documented leak detection

Recommended Whole-Home Setup (Most Popular Choice)

{{brizy_dc_image_alt imageSrc=

One automatic water shut-off valve installed on the main supply line

{{brizy_dc_image_alt imageSrc=

Three to five leak sensors for kitchens, bathrooms, and laundry rooms

{{brizy_dc_image_alt imageSrc=

One rope-style sensor for water heaters or basement areas

This configuration covers over 90% of common household leak scenarios.

Smart Water Protection vs Traditional Leak Alarms

Traditional leak alarms only make noise.

If no one is home, damage still happens.

A smart water protection system can:

Send alerts directly to your phone

Shut off water automatically

Allow remote manual control

Protect your home while you’re away

Integrate multiple sensors into one system

It’s the difference between being warned about a leak andpreventing damage entirely.

Winter Freeze Protection

Frozen pipes are one of the leading causes of major water damage.

Smart systems help by:

Detecting abnormal flow caused by burst pipes

Sending alerts when temperatures drop dangerously low

Automatically shutting off water to prevent flooding

This is especially valuable for homes in colder climates, rental properties, and vacation homes.

Insurance Discounts & Smart Water Valves

Many insurance providers now recognizeautomatic water shut-off valvesas a risk-reduction measure.

2. Qual é a diferença entre AquaNet-BD e AquaNet-VM?

Ambas são válvulas de corte de água inteligentes com todos os recursos, mas a AquaNet-VM vai um passo além.


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 é para monitoramento de alta sensibilidade;AquaNet-BD é para proteção acessível e confiável.

3. Posso conectar detectores de vazamento para desligar a água automaticamente?

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. Continuará a funcionar se acabar a energia?

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. Preciso de um hub ou assinatura para usá-lo?

Sem hub. Sem mensalidades.

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. Quanto custa instalar um sistema de vazamento de água?

Depende de quantas áreas você deseja proteger.

Uma configuração básica com uma válvula de corte automática de água e um detector de vazamento iniciamenos de US$ 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. Vale a pena ter uma válvula de corte de água para Airbnb ou aluguéis?

Absolutely. An automatic water shut off valve paired with leak detectors can prevent major flood damage when no one’s home.

É a melhor proteção para propriedades remotas, aluguéis ou listagens de curto prazo.
