Smart water. Done properly.
Sonic checks every drop eight times a second. If somethingโs wrong, it tells you โ and can shut the water off, even when youโre miles away.
Open Integration System
4.6/5 Star Rated
Award-winning Technology
A circuit breaker for your water supply.
One device on the main pipe can protect every tap, toilet, boiler and appliance in the house.
Custom safety limits
You set the rules. Sonic only steps in if water runs longer than your longest shower โ or goes past a volume you choose.
Autopilot
Pipe bursts while youโre at work?
Sonic can shut off the water at the main. No need to rush home.
Micro-leak radar
Spots a drip as small as one drop every two minutes โ so you hear about a slow leak months before it becomes a soaked ceiling.
Problems found while you sleep.
Sonic checks your water eight times a second, day and night. Quiet hours make even a drip every two minutes easy to spot โ and temperature tracking warns you about Legionella risk or freezing pipes early.
A phone call, not just a notification.
When itโs serious, the Watergate Assistant rings you โ so a burst pipe at 3am doesnโt sit unread on your lock screen. Canโt pick up? Autopilot shuts the water off for you.
See where every litre goes.
Watch water flow through your home in real time and track it by day, week, month or year. Spot the waste, then cut the bill.
Know which appliance drinks the most.
Sonic learns the signature of your shower, bath, washing machine and taps, then shows you exactly how much each one uses. Your water stops being one big number on a bill.

โSuper sensitive and connects straight to your phone. We got a notification and a phone call when we forgot to turn the garden hose off! Brilliant product.โ

โMy kids are at an age where they leave the taps running. I love that Sonic warns me about it. And it warned me when I left the sprinklers running and almost flooded the garden! Weโre using about 20% less water than we did six months ago.โ
