How it works

  1. The water inlet device, solenoid (available in 12V/24V/110V/230V) or inlet pump, delivers clean water to the inside of the toilet bowl.
  2. The macerator pump, integrated in the ceramic toilet, grinds the waste and then moves it to the black water holding tank.
  3. The flush cycle is activated by pressing the control panel buttons.
