Cistern Flush Control Valve

The Water Regulations require a device to regulate the filling of an automatic cistern. This saves water with potentially large financial savings. Control is best achieved with an infrared sensor, which senses a person entering the area and initiates a time delay. At the end of the delay, the cistern starts filling. The Water Watch CFVWW consists of a latching solenoid valve and a sensor/control module. It is preferable to have one unit per cistern, although the cistern can flush several bowls. An AFL servicing valve fitted with a strainer cartridge recommended. The latching solenoid (pulse on, pluse off) minimises the energy requirement enabling the large battery (supplied) to last about 5 years, the LED light provides a visual warning of a failing battery. Alternatively the unit can be mains powered, settings are retained during power failure. Installing and calibrating the unit is simple, requiring the set-up switch to be operated for the filling period. There are no other controls or nozzles to fit. The cistern will flush 30 minutes (factory setting) after the first movement is detected. Flushing can be set to 1, 2, 3 or 4 times per hour. A hygeine flush occurs every 24 hours (factory setting) even when no movement is detected. This reduces odour and replenishes water in the waste trap.
