2.0 Major water leak detection – 1 x LeakSaver 2 alarm panel, 2 x 20” (50mm) Water Meters with pulse readers per unit.
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.
2.1 Flow Control for WCs.
One of the following types of flow control device is fitted to each WC area/facility to ensure water is supplied only when needed (and therefore prevent minor water leaks):
A time controller i.e. an automatic time switch device to switch off the water supply after a predetermined interval
A programmed time controller i.e. an automatic time switch device to switch water on and/or off at predetermined times.
A volume controller i.e. an automatic control device to turn off the water supply once the maximum preset volume is reached.
A presence detector and controller i.e. an automatic device detecting occupancy or movement in an area to switch water on and turn it off when the presence is removed.
A central control unit i.e. a dedicated computer-based control unit for an overall managed water control system, utilising some or all of the types of control elements listed above.
There is commissioning available for the major water leak detection system. It is the responsibility of the mechanical contractor to install the water meters, the valves and fuse spurs to the alarm panels. It is also their responsibility to install the PIR senors and make the connections from these to the valves.
