What is a Waterless Urinal?

Waterless urinal also known as ‘flush free urinals’ are a type of eco-friendly urinal fixture that reduces the need for water to keep the urinals clean. Unlike conventional urinals that rely on water for cleanliness and oduor control, waterless urinal minimize water used in flushes to zero while maintaining higher levels of hygiene. Also, waterless urinal maintenance is a lot less than a conventional one making it an option worth opting for.

How Waterless Urinal Work

There are multiple types of waterless urinal available in the market right now many of which operate on the principle of liquid density. In this design, an oil-based sealant floats on top of the urinal drain, trapping oduors. When urine flows through the drain, it moves beneath the sealant, which effectively captures any unpleasant smells. While it looks like a good solution compared to the conventional urinal even more effective is the use of a membrane that is fixed in the drain trap. This membrane ensures that the oduors can’t escape the drain. Also, the urinal with the membrane trap makes the urinal maintenance easier and the membrane is much sturdier and requires no replacement when compared to the liquid sealant which requires a frequent refill.
