Waterless waste fitting.
The waterless waste fitting is based on a simple principle of a silicone diaphragm that allows urinal to pass through the fitting but stops odours entering the washroom. Waste pipe fitting to the plastic waste fitting is 38 mm without the need for a conventional bottle trap.
