It looks like you have enough room on your stand to rotate the pump head 90* so the outlet is pointing striaght up....i would start there and put a 90* elbow on the bottom so you lines will clear the floor. That "should" solve all your problems...if that doesnt work then i would take the pump apart and verify the Teflon thrust washer is still there and not worn out...may need a new one....and if that still doesnt solve your issues then the next thing i would try is drilling th eimpeller out with a 17/64" drill bit to open the clearences up a tad for more lubrication....you may be on the tight side of tollerances and with your brew having sugars it may be thickening up between the shaft and impeller and introducing drag into the system.
If all the above doesnt cure it then i would send it back here to me and i can check the magnet torques to make sure they are not weak...if need be i will replace them.

Awesome help, thanks. The pump is relatively new, and I only use it for hot water, no wort recirculation. But I'll try shortening the hose, and turning the head 90 degrees and see where that gets me to start with.
Thank you!
