How a Waterless Urinal Works
Cartridge acts as funnel. The non-stick, non-porous
construction and funnel ensure urine passes to the cartridge
and through sealant liquid that floats on top of the liquid
beneath it.
Sealant liquid provides an airtight barrier between urine
restroom to prevent odors from escaping the drain, but
allows urine to pass through because it is lighter than water.
Urine penetrates the sealant liquid and flows to the drain.
Uric sediment is collected by the cartridge, leaving an odor-
free environment, clean pipes and absolutely no water
waste
