Aqua Less lowers consumption to 3.8 liters per flush while keeping the solids-clearing performance of the 3″ valve. The certification extends the system’s coverage to projects that specify consumption below 4 liters.

For a household of four with five flushes a day, switching from 6 to 3.8 liters adds up to more than 16,000 liters a year, without changing the pressure of the existing installation.

The commercial line is adopting Aqua Less progressively throughout the year; updated data sheets are already available in the downloads section.
