What is the plan for the type of overflow?
Single or dual overflows?
Return pump rates?
My recommendation would be to have 4 x 1.5" pipes.
1 for emergency overflow.
2 adjustable running full-siphon (dead silent)
1 minimal leftover flow. (almost silent)
I use 3 x 1.5" pipes. One of which is just emergency. But the other two are pretty close to full-flow.
Using dual DCT-6000 return pumps.
I hate using 2" pipe. So huge, no flex.
