The P1.1 waterless urinal, which is number one on the market, reduces odour that is typical for flushed urinals with poorly maintained ceramic bowls. P1.1 reduces water consumption as well as standard maintenance costs. Cleaning of P1.1 does not take more than 20 seconds per day and everybody can manage it. Our patented P1 valves are the only ones in the market that efficiently block odour for at least 6 months.
