Available in 1/2″ (15mm) and 3/4″ (22mm) sizes, the WLW controller has been manufactured to comply with the requirements of BREEAM WAT03 water leak detection accreditation, and is specifically designed to help protect houses and flats from water leaks, burst pipes or unintentional use of water, i.e., garden hose being left on too long. This is achieved by monitoring the flow of water entering the building, raise an alarm and turn off the water supply if any unusual water patterns are detected, thereby minimising the extent of the damage to the building and its contents. The system can also be fitted with a remote water detection cable or spot probe for areas where appliances use mains water.
Being programmable to suite user requirements, the alarm unit is connected to a 1/2″ or 3/4″ flow sensor and water shut-off valve, fitted just after the internal stopcock. The purpose of the system is to monitor the flow of water entering the building, flat or area, raises an alarm and shut off the water supply when either the flow “Current Flow in L/Min“, or constant flow “Water Flow without a Break“, or volume used “Volume used without a Break” exceeds pre-set limits. The unit displays in real time the three monitored parameters giving instant feedback as to when the water will be turned off. Additional features include, “holiday mode” used when occupants are away for long periods of time, where the system only allows just one litre of water to flow over a period of one hour. “Sleep Mode” this feature stops the flow monitoring for up to eight hours to allow large volumes of water to flow i.e. filling a pond. And “Help” to give useful information about the operation of the system.
The unit can be fitted with a remote water leak detection cable or spot probe to instantly shut down the water supply when a leak is detected. This type of sensor should be used in areas such as kitchens, utility rooms, basements or any area where appliances use water from the mains.
Water Leak Detection cable between 2 and 10 metres long.
Between one and three detection cables can be used to give additional and a quick response to water leaks from appliances such as washing machines, water softeners etc.
Water Leak Spot Probe.
One to a maximum of three spot probes can be used to give a quick response in areas such as utility rooms, basements and pump rooms.
