WG1 Single Zone Major Water Leak Detector

WG1 BREEAM Water Leak Detector

WG1 Major Leak Detection

The WG1 specifically designed to help meet the requirements of BREEAM WAT02 and WAT3 major water leak detection criteria where the mains cold water enters a building at more than one point or where the outside wall of the building forms the property boundary. Designed as a single zone unit it can be used together with the WG2 leak detection system to cover any additional points where the mains cold water enters a building, after the initial point of entry.

  • Designed to help meet all BREEAM requirements for WAT3 where the outside wall of the building forms the property boundary.
  • Designed to help meet all BREEAM requirements for WAT3 when the mains cold water enters the building at more than one point.
  • Designed to help meet all BREEAM requirements for BREEAM WAT02 for monitoring of water consumption in the building.
  • Optional latching valves are available to switch off the water supply should a leak be detected.

The WG1 uses a single turbine water meter positioned on the main cold water pipe just after it enters a building. A pulse unit attached to the water meter signals the amount of water passing through and sends this information to the WG1. The WG1 is fully programmable and can be set to monitor a specific amount of water at a specific time of day. Should this set amount be exceeded at any time, the system will go into alarm.

Typical applications include schools, hospitals, prisons, commercial units, public buildings, office buildings and leisure centres.

It activates when the flow exceeds the pre-set maximum for the pre-set period of time. It can identify different flow and therefore leakage rates and is programmable to suit the owner/occupiers water consumption requirements.
