Early water leak detection isn’t just an advantage for organisations today, it’s an imperative when looking to curb costs, minimise environmental impact, and safeguard reputation. To help customers navigate the complexities of water leaks and understand how to prevent them effectively, we’re shining a light on the transformative potential of Waterguard’s BREEAM and CIREG compliant solutions. Here’s more…

From pools of water gathering near a wall to excess resources gushing out of pipes, some leaks can be glaringly obvious. Others, such as those situated underground or occurring more gradually, are not.

When undetected for a prolonged period of time, it goes without saying that the effects can be detrimental. As well as disrupted operations, structural decay, and spiralling repair costs, organisations can face the brunt of dissatisfied customers and stakeholders. Worse still, legal entanglements can quickly add to the headache of a severe water leak too. 

So, what’s the solution? Investing in an effective leak detector is key. After all, prevention is always better than the cure.

The role of water leak detection technology in effective monitoring

Water leak detection equipment assumes a pivotal role in the vigilant monitoring of water resources. Whether its tracking flow levels within plumbing systems or analysing the time recorded between different points of entry, intuitive sensors empower users to detect leaks and jump into action swiftly.

With this crucial window of opportunity, building owners and site managers can then locate and rectify suspected issues before surplus water escapes. As well as averting substantial damage, this proactive approach bolsters the overall efficiency of water management systems — regardless of the size, nature, or usage of the property.

Working with architects, insurers, consultancy experts and building services engineers, our portfolio of products not only satisfies key BREEAM and CIREG industry standards, but can be tailored to suit a varying degree of requirements throughout the building lifecycle too.

Our Series 7 product simplifies facility management and ensures compliance with insurance requirements. The Waterguard Home and Solo models, on the other hand, provide constant assistance and surveillance to homeowners. They protect their physical assets and give them peace of mind.

How does a water leak sensor work?

Recognising the absence of a ‘one-size-fits-all’ remedy, we’re proud to employ a versatile array of sensors within our leak detection systems. Working alongside key stakeholders including developers and insurers, we design, manufacture, and supply a range of water leak detectors to mitigate the risks associated with both minor and major leaks.

Flow 7

Designed specifically for large complex residential applications, the Flow 7 boasts numerous settings and parameters that help measure water volume in litres or timed usage.

The self-learning audit function keeps track of water usage and detects various flow rates. It uses a pulse sensor to send a signal to the control panel every one or 10 litres of water flow. It will also identify leakage rates — such as continuous and high or low level — over predetermined time periods, to help diagnose and resolve the issue. When user specified criteria is exceeded, the supply is automatically shut off to prevent further damage.


The Home system monitors water flow time in pipes, with a set maximum duration for both occupied and unoccupied properties. The former, known as Low Guard, ranges from 1-30 minutes and the latter, termed High Guard, ranges from 0-2 minutes. The smart valve automatically engages to isolate the water supply if it surpasses the maximum time on either Guard level.

Users can utilise wireless reset fobs to restore supply from anywhere on-site, thereby preventing unnecessary disruption caused by false alarms. Including only WRAS (Water Regulations Approval Scheme) approved plumbing components, the Waterguard Home is a simple and compliant way to prevent water leaks in individual dwellings, as well as high rise and multi-occupancy properties and small offices.

Passive Infrared (PIR)

This BREEAM WAT04 compliant system consists of a PIR controller, remote sensor, and up to three solenoid valves for pipe sizes 15mm-35mm. These systems cut off the supply of both hot and cold water temperatures as well as grey water serving any WC, locker room or other wet room, and are activated when someone enters the space.

The system waits before turning off the supply in highly frequented areas to ensure there is enough supply. It does this after everyone leaves the room, and the delay starts again if someone activates the sensor.

The Waterguard PIR saves water in wet areas, toilets, kitchens, laundry rooms, and water fountains when used with Series 7 systems. 


Covering up to five zones with multiple sensors — including water sensing cable or tape, water sensing feet and/or float switches — the Waterguard Puddle is a leading charge in multi-zone leak detection technology. Sequential audio and visual alerts indicate which channel has been alarmed, if surplus water escape is detected. Intelligent sensing also ensures the Puddle does not re-alarm if the amount of water contacting the devices remains constant.

The systems can be installed in different places, like under floors and above ceilings, in any type of building. Using only WRAS approved plumbing components, the technology complies with key industry requirements too.

Series 7

Suitable for any commercial, public and industrial building, as well as high net worth residential properties, the Series 7 can be installed internally as a single channel system for WAT02 BREEAM compliance or with an additional boundary water metres for BREEAM WAT03. Adhering to CIREG best practice, multiple isolation valves can also be added to mitigate damage and disruption caused during the construction phase of a project. 

As with the Flow 7, the system uses a pulse sensor to monitor typical water consumption and identify leakage rates, and can be used to analyse water usage by volume per half hour, hour, Guard period, or 24-hour timeframe. 


With contractors leaving the site vacant overnight, the risks of water damage wreaking havoc unnoticed overnight can be significant. As well as stalling the progress of the project, this in turn can lead to major reputational and cost implications for parties involved — with lack of or inadequate protection causing premiums to rocket or resulting in loss of cover.

Designed with Contractors All Risk (CAR) in mind, as a proud specialist partner of Aviva, the Waterguard SiteGuard is a programmable solution that isolates sites’ temporary water supply outside of operational hours, and reinstates it upon opening. Although designed primarily for automatic out-of-hours shut off, the solution can also be used in any building needed to isolate the water supply at present times determined by the user. 


An adaptation of our original Series 7 system, the SitGuard+ can be installed on construction sites almost irrespective of their size or phase of development. Following intense trials of the product, exclusive features were added to accommodate complex water usage requirements and prevent unnecessary downtime caused by false alarms. 


With one Guard level set by the installer, landlord or concierge, the Waterguard Solo uses a flow sensor to analyse water usage from the incoming water mains — automatically isolating the supply with a solenoid valve, if the controller suspects a leak. 

Suitable for high rise and multi-occupancy properties, the Solo includes only WRAS approved plumbing components, and also includes a holiday mode whereby the valve is closed and water supply isolated if the utility hasn’t been used for 24 hours.

Are water leak sensors worth it?

You can significantly reduce the headache of leaks and their repercussions by investing in the industry’s best water leak detectors and water sensors. However, they require professional installation, monitoring, and maintenance to ensure you receive maximum bang for your buck, and truly protect your property from surplus water escape. 

In hard water areas, we recommend dismantling the valve assembly of our systems every twelve months and removing limescale build up, for example. We also suggest seeking the expertise of a qualified engineer to replace the battery backup after continued power loss, to safeguard efficiency.

Our leak detection systems can help you save money and reduce the risk of damage from leaking and broken water pipes. Still unsure which product is right for you?
