Using a 90 before return pump inlet?
 

Just wondering how detrimental it would be to use a 90 degree elbow before the intake of a Sequence Hammerhead pump? I'm trying to maximize the amount of room I have next to my sump as well as line up the outlet of the pump closer to the hole drilled in the stand. Thanks in advance :)

Not really, the bigger pipe size the bigger, large enough and the effect will be nil. The hammerhead has a 1.5" I think so you could use 2" inlet piping to minimize effect of 90. You can also use long elbows instead of short.

I have a 90 about 6" from my snapper hybrid with a 2" inlet. There are no micro bubbles or any cavatation that I can tell.

Like Sphelps said, use a long radius 90 or if you have room 2-45's.

Thanks for your help everyone.
