Conservation movements have prompted the invention of new products such as low-flow toilets and waterless urinals. The waterless urinal in public restrooms is applauded by some and booed by others.
What’s important here is they do save water and money and is environmentally friendly.
Some users complain about splash-back due to the lack of moisture and the design of the urinal drain. Some also feel that waterless urinals cause hygiene issues and the biggest complaint is the odor they emit.
Whichever way, it is our duty to save water. There are many water solutions; if you don’t like the waterless urinal then maybe you can install the Multi-Flush which alsa saves a huge amount of water.
