How does a waterless urinal work?
Waterless urinals divert urine through a one-way valve into a “trap.” This trap contains a chemical that is less dense than urine. When the urine flows through this trap, the liquid displaces the urine, forcing it lower into the trap. As this trap fills up, it diverts urine to a drain connected to a sewer.

How often do you change waterless urinal cartridge?
Cartridge Replacement Replacing your waterless urinal cartridges is an essential component of making sure your urinals work like they should. How often you should replace your cartridges should depend on the time elapsed and usage. Typically, you should replace the cartridges about every three to six months.
Why do waterless urinals smell?

The problem arises because waterless urinals need to be cleaned in a different way from traditional flushing urinals. Every time you flush a urinal the limescale in the water used to flush starts to accumulate an absorbent layer in the urinal bowl. Bacteria can then develop in this layer and that results in odour.
Where does the urine go in a waterless urinal?
Waterless urinals all use basically the same science. Urine flows down the bowl of the urinal past a debris-catching strainer. The urine then passes through a sealing liquid, usually a specially designed oil based fluid or simply vegetable oil, and collects in the waste pipe below.
Why do waterless urinals clog?
Now that you know how to unclog a waterless urinal, you should know about how to prevent clogged urinals. Generally, urinals obstruct when uric sediment in the urine deposits on the urinal bowl. Over time it can result in blocked pipe resulting in the clogged urinal.
