SCWD and unfiltered water

[Fish]

Lostmind, I appreciate your experience... I'm worried that the scwd would fail sooner with a low-flow pump than it would with a more powerful pump. I am wondering if it would help if every once in a while I put the pump inlet and scwd outlet lines in a jug of vinegar and water and just pumped it in a loop for a while. The pressure might clean the scwd out better than just a bath... probably clean the pump out at the same time.


I wonder why there is such a wide range of experiences with this device. Some people don't clean them and they last over two years. Some clean them regularily and they fail. Some are silent, some grind...
Are there different models or generations of scwds or is it just "luck of the draw"?
