The H2Zero™ Cube waterless urinal operates utilising unique patented cartridge technology that doesn't use an oil-based seal as used in traditional waterless urinals. Housed within the cartridge the Bio Fresh deodorising block is activated during use, while the Bio Seal™ allows urine to pass through the seal freely. - The Bio Seal™ acts as a one-way air-tight valve to seal the cartridge from the drainage system and against back-pressure situations. This operation guarantees consistently superior performance and hygiene compared to other waterless urinals. - Installation of the H2Zero™ is simplified, as there is no need for a cistern/flush valve to be connected to the unit. After installation the savings continue with a reduction in overall water and waste management charges to buildings.
