Pumps a lot of water for its size and water level sensors work perfectly.

### ⭐⭐ 







  
  
    Bad idea...
  

*by K***V on Reviewed in Canada on 17 April 2023*

When the housing gets dirty it gets wet also the pump is ON till the motor burns. I do not recommend electronic sensor switches any more...
