I'd also turn one of you drains into a back up and split the other one to go to both your refuge and sump. The you'll have a herbie ie less noise. The drain from you're refuge to the sump may also be a source of noise as it currently is?

What is going in the sump? May also want to add a baffle(s) before the return pump if you're planning to put anything in there that could clog up the pump?
