How do waterless urinals work? Why don they smell bad and if they work so well why isn it installed everywhere?
The two main issues that must be addressed for any urinal installation are odour and blockage. Simply turning off the water to standard urinals should not lead to odour. In fact the lack of lime-scale on the urinal surface can reduce smell. While the stale urine in urinal traps is extremely malodorous, this smell does not normally escape into the room, unless of course the trap is leaking onto the floor. This is perhaps less surprising when sink and basin traps are considered. If these are dismantled the resulting rancid smell is extremely unpleasant and yet we wash our faces and dishes in close proximity without the need for lemon-fresh sink plugs. Despite research indicating the lack of odour from un-flushed urinal bowls, most commercial waterless systems incorporate anti-odour measures such as scented pads, sticks, blocks or mats. These scents may be useful for masking general toilet smells but there is little evidence for their need to mask smells from the actual urinal bowl or tra
