Anyone using eductors on return pumps?

I seem to recall eductors needing around 20psi @ 500GPH to be effective so since you may be in the ball park it makes sense to try them out considering they are an inexpensive addition. However I also seem to recall that OM units are not designed to work with eductors so perhaps an email (or phone 1-877-812-4108) to Paul from OM would be a good idea.

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.
