Product Details

Water damage is one of the most common — and costly — home emergencies, with average incidents running $10,000–$15,000 in repairs. This smart water leak detector and automatic shut-off valve installs directly on your main water line and monitors your entire home 24/7, so you don't have to.

How it works: The built-in ultrasonic sensor continuously monitors water flow with precision down to 0.01 GPM — sensitive enough to catch slow drips, running toilets, and pinhole leaks that ordinary systems miss. When abnormal flow is detected, the motorized valve shuts off your water supply in seconds and sends you an instant alert via the Smart Life app.

Full control from your phone: Using the free Smart Life app (iOS & Android, supports 2.4G & 5G Wi-Fi), you can monitor real-time water flow, temperature, and usage from anywhere. Open or close the valve remotely — whether you're at work, on vacation, or just upstairs. Receive push notifications, SMS alerts, and even phone calls when something needs your attention.

Smart AI learns your home: Intelligent algorithms adapt to your household's unique water usage patterns — accounting for family size, daily schedules, and seasonal habits. This reduces false alarms while ensuring fast, accurate responses to real threats like burst pipes and forgotten taps.

Key Features:

  • Ultrasonic micro-leak detection (0.01 GPM sensitivity)
  • Automatic motorized shut-off valve
  • Real-time monitoring: flow rate, temperature & usage history
  • App-controlled (Smart Life) with Wi-Fi remote access
  • 24/7 alerts via push notification, SMS & phone call
  • AI-powered adaptive leak protection
  • Rechargeable battery backup for power outages
  • Compatible with Alexa & Google Assistant
  • Fits standard 3/4" and 1" diameter pipes (adapters included)
  • Professional-grade build with durable ABS housing
  • All installation hardware included

The Threat You Never See Coming

Water damage is the home disaster nobody plans for - until it's too late.

A burst pipe can release up to 1,500 litres of water an hour. A slow leak behind a wall can quietly rot your home for months before you ever notice a stain. By the time you see the damage, the repair bill is already written.

And it almost never happens while you're watching. It happens at 3 a.m., or while you're away for the weekend, or on holiday - exactly when no one is home to turn off the tap.

While you're away, the clock is running.

Most catastrophic leaks happen when the house is empty. Without an automatic shut-off, one failed hose or cracked joint can flood every floor below it - unchecked, for hours or days.

1,500LWater a burst pipe can release every single hour

How Hydrion Protects You

Three steps. Zero effort. Total peace of mind.

Once it's on your line, Hydrion runs silently in the background and only speaks up when it actually matters.

1

It Monitors

A built-in ultrasonic sensor reads your water continuously - flow rate, temperature and pressure - with precision down to a single drip per minute.

2

It Detects

Smart algorithms learn your home's normal usage. The instant something abnormal appears - a leak, a burst, a tap left running - Hydrion flags it.

3

It Shuts Off

The motorised valve closes your water supply in seconds and sends an instant alert to your phone, stopping the damage before it spreads.

1 drip / minute
Upgraded ultrasonic detection senses flow from 0.001 up to 18 gpm - catching the slow, silent leaks ordinary systems miss entirely.

Everything you need to never fear a flood again.

Ultrasonic Micro-Leak Detection

Instant Multi-Channel Alerts

Get notified the second something's wrong - by app push notification, SMS, and even a phone call. You will never miss it.

It paid for itself in one weekend
We were away when a hose under the sink let go. I got a phone alert, opened the app, and the water was already shut off. No flood, no claim, no €10,000 repair. I cannot recommend this enough.

My insurer gave me a discount
Installed it, sent a photo to my home insurance, and they actually lowered my premium. The device is basically paying for itself every year now. Setup took one afternoon.

Caught a leak I never would have found
The app flagged a tiny overnight flow that turned out to be a running toilet valve. Nothing dramatic, but it had been quietly wasting water for who knows how long. Fixed it the same day.

We finally relax when we travel
We used to shut the water off at the main every time we left for holiday. Now I just tap 'close' in the app from the airport. Coming home to a dry house instead of worrying the whole trip is worth every cent.

The display tells me everything
I am not a tech person, but the screen and the app are dead simple. Flow, temperature, pressure - all right there. When everything reads normal it just says protected, and I forget about it.

Wish I'd had this years ago
We had a burst pipe in 2019 that cost us a fortune and months of renovation. This would have stopped it in seconds. We are installing one on every property we own now.

Your Next Trip Away

Two ways the same weekend can end.

The difference between a story you laugh about and a claim you'll never forget is about ten seconds of reaction time.

Without Hydrion

You come home to this

A joint fails on Saturday morning. Nobody is home to hear it.
Water runs for two days across every floor below.
Ruined floors, soaked drywall, warped furniture, mould.
Weeks of repairs, a five-figure bill, and an insurance fight.
VS
With Hydrion

You get a notification

Hydrion senses the abnormal flow within seconds.
It closes the valve automatically - the leak stops at a trickle.
Your phone buzzes: a leak was detected and handled.
You come home to a dry house and a story, not a disaster.

Common Questions

Everything else you might be wondering.

Will it fit my pipes?
Hydrion fits standard 3/4" and 1" diameter water lines, and both copper adapters are included in the box. It installs inline on your main supply line. If you're unsure about your setup, send us a photo at info@gethydrion.com before you buy.
Does it include the wireless spot sensors?
No. Hydrion protects your whole home from the main line using its built-in ultrasonic flow sensor - it does not need any add-on pucks to work. Optional wireless spot sensors for individual rooms are available separately.
What happens during a power cut?
A built-in rechargeable battery keeps Hydrion monitoring and able to shut off your valve even when the power is out - which is often exactly when problems happen.
Does it need Wi-Fi to work?
The automatic shut-off and on-device alarm work on their own, even offline. Wi-Fi (2.4G and 5G supported) unlocks the app: remote control, phone and SMS alerts, and live monitoring from anywhere.
Will it restrict my water pressure or flow?
No. Hydrion is engineered to monitor your full flow without restricting it, so your taps and showers feel exactly the same as before.
How does it avoid false alarms?
Its smart algorithms learn your household's normal water patterns over time - accounting for family size, routines and seasons - so it reacts fast to real leaks while ignoring everyday usage.
Can I install it myself?
Yes. Most people install it in 20-30 minutes using the included adapters and instructions - no special tools needed. For older or non-standard plumbing, we recommend a professional plumber.
