So the urine passes through into the sewer line and doesn't stick around in the urinal. This is a new technology so there is not a lot of data on how well they work. Some possible issues are maintenance and cost—how often you change the canister and how much it costs. It saves water for sure! Hi Tim,

No flushing. I wonder how these work and why they are not more common. I saw water free urinals at a public restroom once. No flushing. I wonder how these work and why they are not more common.
