Compare the approaches
A valve that closes itself, or a stopcock and a sprint.
A manual stopcock works perfectly, as long as someone is on site, knows where it is and reaches it in time. Automatic isolation removes all three conditions. The manual valve still has a role, but for stopping a leak fast the auto-isolation valve wins.

Manual isolation is too slow.Reaching a stopcock depends on someone being on site, knowing where the valve is and turning it in time, which rarely happens as a leak begins.
Leaks do not wait for working hours.A burst at 2am runs for hours before the first person arrives, and a closed valve is the only thing that actually stops the water.
A burst pipe is rarely cheap.The average burst-pipe claim was around 7,500 pounds in 2024, and most of that cost comes from the water that ran before isolation.
Whole-building isolation is disruptive.Turning off one stopcock can take water from floors that were never affected, so isolation needs to be local where it can be.
The AQUAIOT SolutionRequest a Consultation
How fast the water actually stops
Manual isolation depends on a person. Someone has to notice the leak, get to the building, find the stopcock and turn it, and every minute the water keeps running. That is far too slow when a pipe has already burst, and it simply does not happen overnight or at weekends. AQUAIOT replaces the wait with logic and motorised valves. The moment a moisture sensor or flow rule trips, the auto-isolation valve closes the supply and escalates to the duty holder, who can re-open or override it remotely once the cause is known. The manual valve stays in place as backup.
Manual depends on a person being there. A stopcock only helps if someone is on site, knows where it is and turns it in time, which rarely lines up with the moment a leak starts.
Auto-isolation acts in seconds. Motorised valves close the supply automatically on a moisture or abnormal-flow trigger, day or night, without waiting for anyone to arrive.
Control still sits with a person. The duty holder gets a role-based alert and can re-open or override the valve remotely once the cause is found, with the manual valve kept as backup.

How It Works
Three steps from first drop to evidence
Step 01
Detect
AQUAIOT moisture, flow and freeze sensors are deployed at the points water escapes. Every reading is timestamped and logged to the cloud over secure cellular or LoRaWAN telemetry.
Step 02
Alert and isolate
When moisture is sensed or flow goes abnormal, AQUAIOT raises an immediate alert by SMS, email and app, and closes the auto-isolation valve so water is stopped before damage spreads.
Step 03
Record
Every reading, alert and isolation event is captured in exportable, timestamped logs that integrate with CAFM and BMS, so evidence for insurers is ready on demand.
Capabilities
Everything a leak detection programme needs
Purpose-built for estates, facilities and risk teams protecting buildings against escape of water across single or multiple sites.
Moisture sensing at the risk points
Point, rope and tray sensors detect water at first contact under appliances, in plant rooms, risers and tank rooms, before it spreads.
Inline flow analytics
Continuous flow monitoring on the incoming main learns normal use and flags the slow weep or continuous draw a manual check never sees.
Freeze protection
Temperature monitoring on exposed and loft pipework warns before a freeze leads to a burst, so action can be taken in time.
Automatic shut-off
Auto-isolation valves close the supply the moment a moisture or abnormal-flow threshold is crossed, with manual remote override for the duty holder.
Multi-channel alerts with escalation
SMS, email and app alerts with role-based routing, so the right person responds day or night, on a single site or across a portfolio.
Open integration, no lock-in
Connects to BMS, CAFM and SCADA via RS485/Modbus or REST API, with audit-ready exportable records for insurers and owners.

Questions & Answers
Common questions
Is a manual stopcock still worth having?
Yes. The manual valve stays in place as a reliable backup, but on its own it only stops a leak when someone is present to find and turn it in time.
How fast does automatic isolation act?
In seconds. The motorised valve closes the supply the moment a moisture or abnormal-flow threshold is crossed, day or night, with no wait for someone to arrive.
Can a person still control the supply?
Yes. The duty holder receives a role-based alert and can re-open or override the valve remotely once the cause is found, so control always sits with a person.
Can isolation be limited to one zone?
Yes. Valves on branches feeding high-risk areas let you cut only the affected supply, so the rest of the building stays live while the team responds.
Will fitting valves disrupt the building?
No. Valves and clamp-on ultrasonic flow monitoring are retrofit-friendly and non-invasive, fitted without cutting into pipes or shutting the building down.
