Stop a leak
the moment it starts.
Most water damage starts as a leak no one sees. CubicSecure watches your water around the clock and shuts the main off automatically — usually before a single drop reaches the floor.
Small enough to fit any service hatch. Smart enough to act on its own.
Detect, decide, shut off.
All before the floor is wet.
Detect
CubicSecure measures flow continuously and runs a daily pressure test. Either signal flags a possible leak.
Decide
The algorithm runs on the device itself, fully offline. Brief events like a flush or quick wash are filtered out before action.
Shut off
The motorised valve closes in ~10 seconds. Water stops here, before the leak hits the floor.
Time-of-flight, nanosecond precision.
The inline unit fires ultrasonic pulses down into the flow. Two internal mirrors reflect the signal to travel strictly parallel to the water — one pulse riding with the flow, the other fighting against it.
Sound travels at roughly 1,480 m/s through water. When water flows, it carries the downstream pulse a hair faster and slows the upstream pulse by an equal amount. The sensors resolve time differences down to a few nanoseconds — sensitive enough to detect incredibly low flow rates.
See it stop a leak — automatically.
Pick a leak type and press Simulate leak. CubicSecure watches the flow continuously, classifies what it sees, and closes the valve automatically when a leak is confirmed. You don't have to be home. You don't have to do anything.
The valve closes automatically. CubicSecure shuts the water off when sustained flow crosses either threshold: 1,500 L/h for 90 seconds (burst), or 6 L/h for 45 minutes (medium leak). Both thresholds can be adjusted in the Quandify app to match your home's normal flow patterns. Detection and shut-off behaviour are validated by RISE Research Institutes of Sweden.
Prevent water damage
Smart and automatic water shut-off
The leak you'd never see, caught while you sleep.
Once a day, when no one's using water, CubicSecure briefly closes its valve and listens to the pressure. If pressure stays steady, your plumbing is tight. If it drops — even a fraction of a bar — there's a hidden leak.
Plumbing is tight
Pressure held steady. The valve reopens quietly. Test runs again tomorrow.
Hidden leak detected
Yellow LED and push notification — most often a slow-running toilet. Left unaddressed, the device can escalate and shut the water off.
Test interrupted, retry
Someone used water mid-test or another condition interfered. No alarm — the device retries on the next cycle.
