Stream with lime build-up
Rub the lime away with the finger
The stream is smooth and splash-free again

Lime Resistance

Lime builds up in the middle of the wire mesh screen and also fills the space between the insert and the housing, slowly closing the air inlets. The water stream loses aeration and splashes.

 

 

 

CASCADE® aerator with its unique design slows down lime build up. Even after being subjected to the accelerated aging procedure, CASCADE® aerator produce a straight, round and splash-free water stream.

 

 

Evaluation of aerators with wire mesh screens and CASCADE® aerators. Two new aerators have been tested in the following conditions:

  • accelerated aging: simulation of the equivalent of 5 to 6 years of use in average conditions;
  • water temperature of approx. 20° C/68° F;
  • room temperature of approx. 20° C/68° F;
  • water hardness of 20° to 30° (German hardness).
