Easy-fit universal water-saving device for all urinals. Conveniently fits into any urinal – even those that have been adapted to accept retro-fitting systems which have been removed, leaving an open hole. Contains well-proven biological block, which cleans and deodorises the urinal trap while also preventing the build-up of scale and solids. By reducing the flushing frequency to three times within 24 hours, urinals are maintained in optimum condition and dramatic water savings enjoyed. Use in conjunction with Toilet Cleaner to maintain an odour-free washroom environment.
