Leak detection guide
How to prevent burst pipes, before the cold hits.
Burst pipes are among the most preventable causes of escape of water, yet they spike every winter. This guide sets out practical prevention steps for UK buildings, then explains where monitoring adds the early warning manual steps cannot.

Empty buildings are the real risk.A common mistake is letting a building go fully cold over a weekend or holiday, which is exactly when pipes freeze with no one on site to notice.
Insulation reduces risk but gives no warning.Lagging and trace heating lower the odds of freezing, but they cannot tell you when a run is approaching freezing, which is where monitoring fills the gap.
Small drips freeze fastest.A slow weep at a worn joint freezes more readily than a full flow, so unfixed minor faults often become the first runs to split in a cold snap.
The split often leaks on the thaw.Many burst pipes only release water as they warm, so prevention has to include catching the leak during the thaw, not just stopping the freeze.

Practical steps, plus the warning layer
Preventing burst pipes is mostly about keeping water above freezing and getting early warning when it is not. The practical steps are well established. Lag exposed pipes in roof voids, plant rooms, car parks and outbuildings with proper insulation, and add trace heating to the runs most at risk. Keep buildings gently heated through cold spells rather than letting them go fully cold when empty over weekends or holidays. Fix dripping taps and known weak joints before winter, since a slow weep freezes faster. Know where the stopcock is and that it turns freely. Drain down systems in buildings left unoccupied for the season. These steps cut the odds, but none of them tells you the moment a run is approaching freezing or has already started to leak. That is the layer monitoring adds. AQUAIOT watches temperature on at-risk runs and alerts before freezing, senses moisture where water would pool, and can close an auto-isolation valve the instant a split starts to leak on the thaw.
Insulate and heat the weak runs. Lag exposed pipes in roof voids, plant rooms and outbuildings, add trace heating where needed, and keep buildings gently heated through cold spells rather than fully cold.
Fix small faults before winter. Repair dripping taps and known weak joints early, since a slow weep freezes faster, and confirm the stopcock turns freely before you ever need it.
Add the warning manual steps cannot. Temperature monitoring on at-risk runs alerts before freezing, and moisture sensing with an auto-isolation valve catches and stops a split that leaks on the thaw.

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
How do I prevent burst pipes in winter?
Insulate exposed runs, add trace heating where needed, keep buildings gently heated through cold spells, fix dripping taps early, and know that the stopcock turns freely.
Why are empty buildings most at risk?
A building left fully cold over a weekend or holiday lets pipes drop toward freezing with no one on site, which is when most preventable burst pipes happen.
Is insulation enough to prevent burst pipes?
It helps but gives no warning. Lagging and trace heating lower the odds, while temperature monitoring tells you when a run is approaching freezing in time to act.
Why fix small drips before winter?
A slow weep at a worn joint freezes faster than a full flow, so an unfixed minor leak often becomes one of the first runs to split when a cold snap arrives.
How does monitoring help prevent burst-pipe damage?
Temperature sensors warn before a run freezes, moisture sensors catch water if a pipe splits, and an auto-isolation valve can stop the supply the moment a thaw leak starts.
