How Does a 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. … Over time, this liquid, usually some type of oil or gel, needs to be replaced.

How do urinals flush?

Hydraulic valve urinal flush controls such as the Cistermiser range are installed in-line with the water supply inlet pipe into the cistern and sense short-term drops in pressure within the water supply. Each time a drop in pressure is identified the valve releases a measured amount of water into the cistern.
