Bio P is an easy-fit universal water-saving device for all urinals. It conveniently fits into any urinal - even those that have been adapted to accept retro-fitting systems which have been removed, leaving an open hole. The Bio P contains a 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.
