How does a waterless urinal work anyway?
The secret of how waterless urinals work is the trap fluid that floats on the top of the heavier liquids inside of the urinal drain trap. The trap fluid is an odor absorbing fluid that seals the top of the trepans all of the heavier liquids entering the urinal pass through the lighter trap fluid and go down through the drain. A janitor will wash out the waterless urinal trap by pouring a bucket of water down the drain and then resealing the trap by pouring a cup of the “green” environmentally friendly fluid back into the trap. It is necessary to spray the urinal once a day with cleaning fluids and to change the urinal trap fluid twice a month. What is the payoff? How about saving as much as 40,000 gallons of water per year per urinal.
