How a Waterless Urinal Works
When the urinal is used, urine is directed into a collection area in the center of the cartridge. Inside the collection area of the cartridge, a sealant liquid remains at the top of the opening. This sealant layer allows the urine to pass through it, keeping urine blocked underneath so sewer gases and urine odors cannot escape into the restroom. Once the collection area of the cartridge has filled to a designated point, an internal trap directs the urine to an outlet, letting it flow into the drain line and out of the urinal cartridge.
Selecting a Waterless Urinal
Similar to a standard water-flushing urinal, waterless models come in many styles, colors, and brands, and they're often selected based on a preference of usage and style. When choosing a waterless urinal, be sure to check the "number of uses" of the cartridge before it needs to be changed to ensure it's sufficient for your application. Depending on the urinal, the cartridge use can range from 2,000 to 10,000 flushes.
Connecting a Waterless Urinal
Although waterless urinals don't use water to remove urine, they do still require a drain connection. Most urinals connect to the waste pipe with either a 1½" or 2" threaded connection. Waterless urinals come with an integrated 2" connection and can be reduced to 1½" with a reducer bushing. They can be easily mounted in place of existing water-flushing urinals, and are great to use in applications where storage of wastewater is required.
Maintenance and Cleaning
Depending on the waterless urinal manufacturer, a specific tool may be needed to change the cartridge. The cartridge or urinal may include manufacturer specifications that suggest which products to use to clean the urinal and refresh the liquid sealant. Cleaning a waterless urinal is the same as cleaning a standard water-flush model. However, it isn't necessary to flush the urinal with water after cleaning. Many manufacturers have spray cleaners that save time and water and are designed specifically for use on waterless urinals.
It's always good to outfit your bathroom with hand sanitizers and restroom dispensers for a clean environment.
