I might have to put one 90 on the intake of my Reeflo cuda...is that going to cause any trouble? I dont think it would but I know you shouldnt restrict the intake of the pump. Its 1.5" on the pump...should I make the elbow and plumbing up to the intake 2" and reduce at the pump or will all 1.5 be good. I am talking about on the outside of the sump too...there will be at least one more 90 in the sump to draw water from the bottom close to the glass so it doesnt suck air.
