Water Leak Detection Systems for Multi-Apartment Blocks

Aqualeak – Protecting multi-apartment developments against the risk of costly and disruptive water damage.

Aqualeak offers a range of flow monitor devices and sensor-based alarm panels that are suitable for installation on an apartment-by-apartment basis in multi-resident blocks of all types.

Our systems quickly and effectively identify when a leak has occurred, either as a result of burst or faulty pipework, or due to blocked soil or drainage stacks, that can prove hugely problematic in high-rise multi-apartment buildings.

Systems operate 24 hours a day, 7 days a week, 365 days a year, giving complete peace of mind that properties are being protected at all times, regardless of whether it is occupied or unoccupied.

When leaks are detected, a number of actions can be triggered, including the closure of an automatic shut-off valve, a signal to a central Building Management System or alert notifications to multiple users, including residents, building managers and concierge.

Our water leak detection systems are approved and recommended by many of the world’s largest insurance companies and can help developers, asset owners and property managers meet escape of water requirements for insurance policies.

Our systems are also often used in the Shell & Core elements of new build projects, including to monitor and protect service risers, lift shafts, plant/boiler rooms and beyond. If you are seeking to achieve BREEAM points for a development, we can also supply systems that comply with WAT criteria.

We are highly experienced at working at all stages of a project; from early stage design and specification advice, through to large retrofit and refurbishment programs.

Our most suitable systems for this application are outlined below:

AquaGuard Dual

  • A cost-effective, hybrid water leak monitoring and protection device
  • Monitors the volume and time water passes through a pipe, comparing against adjustable thresholds to identify excessive and unexpected flow
  • Simultaneously monitors multiple sensing devices (cable and/or probes) to detect the unwanted presence of water in at-risk areas
  • When a leak is detected by either method, a valve automatically and immediately closes and shuts off the water supply, minimising damage
  • Audible and visual alarm
  • ‘Holiday’ mode where water is automatically shut off after a pre-set period of time if no flow is detected
  • Most suitable for monitoring in new build residential property, ranging from individual houses through to multi-apartment blocks (typically one device per apartment)
  • Can be connected to a central BMS or send notifications of a leak when paired with an SMS unit
  • Can be surface or flush-mounted
  • Suitable for multiple pipe sizes
  • WRAS-approved
wras approved product


WATER FLOW MONITORING domestic water leak detector
  • A market-leading inline residential water leak detection and prevention device

  • Specifically designed for installation in new build or retrofit residential applications

  • Monitors the volume and duration of water passing through a pipe, against pre-set thresholds to identify excessive and unexpected flow

  • If thresholds are exceeded, a solenoid valve will automatically close and shut off the water supply

  • Installed on the cold-water pipe, just after the stopcock

  • Operates using a roving handset, which can be battery or mains-powered

  • Allows for flexibility around different users’ varying water usage and can be manually over-ridden when necessary

  • Can also automatically shut off the water after a pre-set period of time if no flow is detected

EMS-5 & 10

MULTI ZONE SENSOR-BASED water leak detectors 
  • The EMS-5 and 10 water leak alarms are designed to detect water leaks in sensitive areas where high value equipment and/or data is present
  • Ideal for monitoring up to 10 individual zones
  • When the leak detector is triggered, an audio-visual alarm is initiated and the water leak alarm panel shows you where it is
  • Can connect to water leak sensor cables, probes and pads; users are alerted to any faults with sensor equipment, including cable damage and broken connections
  • A signal to a BMS can also be triggered via a relay
  • Can connect to a solenoid valve, enabling automatic water shut off in the event of a leak
  • Additional relays are also available, allowing for extra functionality tailored to specific zones


Single Zone SENSOR-BASED Water Leak Detection alarm System
  • Designed to continuously monitor for water leaks in single-zone, at-risk areas

  • When the sensor detects water, a localised audio alarm is activated and an LED is illuminated; other actions, such as sending a SMS notification, are also available

  • Can connect to a solenoid valve, enabling automatic water shut off in the event of a leak Monitors distances of up to 100m from the panel

  • A signal to a BMS can also be sent via a relay

  • This leak detection alarm can connect to a range of sensing technologies such as cables and probes; users are also alerted to any faults with water leak sensor equipment, including cable damage and broken connections
