How Does a Waterless Urinal Work?
Typically, waterless urinal bodies are constructed of vitreous china or porcelain, similar to standard flush urinals. Most waterless units use a liquid sealer and rely on a density differential between the sealant and the liquid waste. The sealant is less dense than water or urine, which pass through the sealant. The sealant creates a barrier between the liquid waste and the urinal bowl.
