Well update:
Ran the pump, and I have 1 leak and 2 cracked bulkheads... frown. The leak is an easy fix, just need 2 new bulkheads for the returns.
I also called Dolphin today, and they said I can safely valve the pump back more than even half way. Their pumps have certain motors that sense the change and use less power.
Looks like I have some work to do, good news is I can keep my pump (for now anyway)
