    Did you use the same 1" return line that comes off of the pump?

    That's what I was running and I also had a loud hum from the Mag 24. Found out that the 1" return is way too small for the flow of that pump. Switched to 1-1/2" return, and the pump was much quieter. The flow coming out of the pump is MUCH greater at 1-1/2", also.

    Oh well I didn't think about my plumbing very well and I can't easily change out the return line unless I plug the holes in the tank lol. So I am in the market for a new pump.
