I'm gonna start hard plumbing my tank soon and I'm using 3/4" return and a 1" drain. My question is, when I plumb the drain do I want it to go straight down into the sump or should I add an elbow to it? It's gonna have a gate valve, a union and then the plumbing to the tank. I wonder that if I make it straight down if it'll be any louder than with a corner. Another thing is that I want it to drain as much as possible cause the return is powered by a mag 9.5 and I think im gonna have to dial that down a bit with a gate valve for a 1" drain.
