The world has changed. Water is no longer abundantly available, even in "First World" countries like the USA. Dwindling natural resources, climate change, the need to reduce and/or conserve budget money plus behavioural changes have led to an increased awareness, desire and need to install water conserving fixtures. No-Flush urinals work completely without water or flush valves. Flushed fixture overflows and leaks are high priority items with maintenance departments. Waterless urinals are the absolute best long term solution for water efficiency and maintenance reduction.Waterless No-Flush urinals resemble conventional fixtures, and easily replace them. They install to the regular urinal 2 (52 mm) waste line (for 1 (38 mm) waste lines, use a reducer bushing). They eliminate flush water supply lines. Flush valves are completely eliminated as well. No handles to touch, no sensors to install or adjust, no moving parts at all! The urinal bowl surfaces are smooth and urine repellent; urine is 95% liquid and its drainage is effected without flush water through gravity. Daily cleaning procedures are the same as for flushed urinals, yet save time per urinal. The conventional water-filled urinal trap is replaced by a disposable EcoTrap inserted in the urinal drain outlet of our urinals. It holds a layer of the proprietary immiscible BlueSeal liquid, floating on top of a urine layer. The combination of our EcoTrap and the covering BlueSeal blocks out sewer gases and urine odors from the restroom. 90 ML dose of BlueSeal lasts up to 1500 uses, replacing from 1000 and up to 4500 Liters of quality potable flush water at each fill!!
