Anyone using eductors on return pumps?

Yes, I have read this mentioned a couple times as well, but can't find any specific information. I'm not sure why it would affect an OM. I will look into it.

EDIT: Just found this...the back pressure from the eductors can put pressure on the drum of the OM and although it doesn't cause damage, it will prevent the drum from turning. There seems to be a way around this... keep posted.
