The drain system in a waterless urinal plays a crucial role in managing urine flow and preventing clogs. It consists of a specially designed drain insert or insert cartridge that connects to the urinal bowl. The insert is typically made of a durable material like polypropylene or stainless steel, which is resistant to corrosion and buildup.

Inside the insert, there are small holes or slots that allow urine to flow through and into the plumbing system. These openings are strategically positioned to encourage the flow of urine while preventing debris or foreign objects from entering the drain. The insert also helps to distribute the urine evenly, enhancing the effectiveness of the liquid sealant in the cartridge and minimizing odors.

The Cartridge System

The cartridge system is a key component of waterless urinals, responsible for capturing and eliminating urine and odors. It typically consists of a cartridge housing made of durable plastic or stainless steel, which holds the liquid sealant and urine. The housing is designed to be easily removable and replaceable for maintenance purposes.

Inside the cartridge, there is a layer of the liquid sealant that creates a barrier between the urine and the surrounding air. As urine flows into the cartridge, it displaces the liquid sealant, which fills the cartridge and traps the urine. The liquid sealant also contains enzymes that break down odor-causing bacteria, further enhancing odor control.

Periodically, the cartridge needs to be replaced to maintain optimal performance. This is typically done by removing the cartridge housing from the urinal, emptying the contents into a drain, and installing a new cartridge.

Maintenance and Cleaning

Maintenance and cleaning of waterless urinals are relatively simple compared to traditional flush urinals. Regular cleaning involves wiping down the urinal bowl with a mild cleaner and a non-abrasive sponge or cloth, ensuring the cartridge housing remains clean and odor-free.
