Meet the requirements for BREEAM WAT02 (Consumption) and WAT03 (Major water leak detection) with the LeakSaver alarm. Connect to 1 or 2 water meters installed on the incoming mains water service. We also have PIR flow control for WC areas (WAT03) including valve sizes between 15mm and 80mm.
We also have the unique Ydrostop water fuse, which requires no external power at all, it is a completely mechanically operated device. The Ydrostop will automatically switch off the water supply should a pipe burst or there is continuous flow above a pre-set length of time.
BREEAM and flow based leak detectors
The LeakSaver has been specifically designed to achieve the requirements for BREEAM WAT02 (consumption) and WAT03 (major leak detection). It monitors the flow of water using water meters positioned at the boundary and where the MCWS enters the building. Let us help you specify the BREEAM WAT 02/03 on your project.
BREEAM WAT03 automatic flow control for WC areas using PIR sensors connected to WRAS approved solenoid valves. This effective proven solution offers reliability and easy installation at a reasonable cost, helping to make this BREEAM credit one of the easiest to obtain.
The Ydrostop automatic water shut off valve offers a unique mechanical solution for monitoring the flow of water running through a pipe. Requiring no electrical power, it continuously checks the water flow against a user defined set period of time, if exceeded it will immediately shut off the water.
Combine the unique features of a flow and sensor based water leak detection alarm with the new Imrita smart complete leak detector. Ideal for houses, flats and apartments, this is the easy solution for contractors and individuals looking for a proven method for water leak detection.

- Able to identify different flow and therefore leakage rates.
- Programmable to suit the owner/occupiers’ water consumption criteria.
- Where applicable, designed to avoid false alarms caused by normal operation of large water consuming plant.
BREEAM (Building Research Establishment Environmental Assessment Method) is well recognised as the construction industry standard for assessing the sustainability credentials of a building. It covers a broad range of environmental and sustainable issues and can be used by designers, developers, architects and managers to demonstrate measures have been taken that ensures their building meets a certain standard. There are essentially 3 ratings, very good, excellent and outstanding with this method of assessment. It is used in the construction of Courts, Schools, Healthcare establishments, Industrial buildings, Multi residential blocks, Offices, Prisons, Retail, Hotels and Leisure complexes.
BREEAM water leak detection products WAT02 WAT03
The LeakSaver product monitors the flow of water through a pipe. This system is used to meet the requirements of BREEAM WAT02 (monitor of consumption) and WAT03 (leak Detection). The alarm panel is connected to water meters that send pulses relating to water usage, e.g. one pulse for every 10 litres of water. The panel is programmed with the expected amount of water usage, based on the type of building, the occupancy and the amount of facilities using water, if the flow of water exceeds this setting an alarm will be triggered.
The Leaksaver is a water leak detection system capable of detecting a major water leak on the mains water supply within the building and between the building and the utilities water meter. It monitors the amount of water passing into the building over a set period of time. Should this amount be exceeded it will create an alarm. It can be used when there is external pipe work between the boundary and the building. This enables the distinction between a leak outside (usually underground) and one inside the building.
The LeakSaver can also be used for “Water Monitoring”. The aim of WAT02 is to manage water and encourage reductions in consumption. A pulsed water meter is required on all mains supplies and on the supply to any building using more than 10% of the total water consumption. The LeakSaver connects to the water meter/s and to the Building Management System to monitor the amount of water used.
The system has been designed to meet all of the WAT03 requirements for BREEAM water leak detection and prevention, the key points being:
An alarm is raised when the flow of water exceeds a pre-set maximum for a pre-set period of time. It is able to identify different flow rates by programming high and/or low levels over different time periods. It is fully programmable to suit the users water consuming requirements and has the ability to avoid false alarms when larger volumes of water are called for.
Wat 02 Water monitoring: Number of credits available (1)
Aim: to ensure water consumption can be monitored and managed and therefore encourage reductions in water consumption.
Assessment Criteria
The following is required to demonstrate compliance:
The specification of a water meter on the mains water supply to each building; this includes instances where water is supplied via a borehole or other private source. Water-consuming plant or building areas, consuming 10% or more of the building’s total water demand, are either fitted with sub meters or have water monitoring equipment integral to the plant or area. Each meter (main and sub) has a pulsed output to enable connection to a Building Management System (BMS) for the monitoring of water consumption. If the site on which the building is located has an existing BMS, managed by the same occupier/owner (as the new building), the pulsed water meter(s) for the new building must be connected to the existing BMS.
Wat 03 Major water leak detection: Number of credits available (1)
Aim: To reduce the impact of water leaks that may otherwise go undetected.
Assessment Criteria
The following is required to demonstrate compliance for one credit.
A leak detection system which is capable of detecting a major water leak on the mains water supply within the building and between the building and the utilities water meter. The leak detection system is:
Audible when activated
Activated when the flow of water passing through the water meter/data logger is at a flow rate above a pre-set maximum for a pre-set period of time
Able to identify different flow and therefore leakage rates, e.g. continuous, high and/or low level, over set time periods
Programmable to suit the owner/occupiers’ water consumption criteria
Where applicable, designed to avoid false alarms caused by normal operation of large water-consuming plant such as chillers.
Wat 03 Water leak prevention: Number of credits available (1)
Aim: To reduce the impact of water leaks that may otherwise go undetected.
Assessment Criteria:
A flow control device is fitted to each WC area/facility to ensure water is supplied only when needed (and therefore prevent minor water leaks):
Uses PIR (passive infrared) sensors connected to valves fitted on the main water supplies to the area. When someone enters the toilet, the PIR activates and the valves open allowing water to flow in. After the area’s been vacated the valve automatically closes, switching the water off again.
BREEAM offer 1 credit (under WAT03) for fitting a flow control system to all WC areas in a building to minimise the impact of minor water leaks. Toilet areas that have a common water feed can be served by several PIR sensors connected to a single valve. Fitting a PIR flow control system to all your WC areas will:
1.Reduce loss of water through undetected leaks.
2.Help to prevent large scale flooding due to burst pipes or vandalism.
3.Minimise water being wasted when taps are left running.

Valves for (BREEAM WAT03) water leak detection
Valves for (BREEAM WAT03) water leak detectionMajor leak detection: Connect a 24VDC normally closed or normally open solenoid valve directly to the LeakSaver alarm panel and switch off the mains water supply as soon as a leak has been detected. Although not a requirement for achieving BREEAM, fitting shut off valves will save the loss of large volumes of water should a leak occur and the building is unoccupied.
Valves for automatic flow control in WCs (BREEAM WAT03)
Connecting a brass solenoid valve to a PIR (Passive Infrared Sensor) that activates only when the facility is occupied. Can save water should there be a leak or malfunction of the plumbing equipment. The PIR acts like a switch holding the valve open for a pre-set length of time after somebody enters the room. The valve then remains open for a set length of time allowing the water to flow to the cisterns and taps. Once the room has been vacated, following a short delay, the valve will close and the water supply shut-off.
Valve Features
- Normally open or normally closed solenoid valves for use with the Leaksaver (24VDC).
- Normally closed solenoid valves for use with PIRs from 1/2″ to 3″ (230VAC).
- Normally closed are WRAS approved.
- More than one valve can be connected in parallel.
Description
- YdroStop flow based leak detectors work like a fuse in your plumbing system
to reduce the risk of serious flooding in the event that a pipe bursts or a tap is left on. - YdroStop shuts off the water supply if it detects persistent continuous water flow, a leak, or a burst pipe.
- Ideal for houses, flats, holiday homes, small commercial buildings and farms.
- When it detects a sudden pipe burst, it shuts off the water supply immediately.
- In response to continuous water flow (leaks, taps running, etc.), YdroStop shuts off the water after a pre-set amount of time.
- Prevents unnecessary water consumption due to leaks or open taps, saving money and helping to protect the environment.
- Does not require electricity to operate. No need to monitor battery life or worry about power outages.
