Basement sump in the works and I could use some help:
Here goes:
My house is a tri-level with the lower floor being half finished, half unfinished storage/laundry room slash new fish room.
On the main level I have a standard 6' 125g tank with dual overflows (standard 1" drains per). In the finished portion of the lower level I have a 75g with single overflow and a 25g with a drilled in overflow box. The goal is to have all three tanks merged into one system via the sump.
Sump itself is halfway complete and is 48"x20"x20". I have two iwaki 70 return pumps (side note: I talked to Iwaki and they felt that I would need to run both pumps to accomplish my goal. Please let me know if you think differently). Total vertical head is 15' with apx 50' of horizontal. When I add in bends and valves the calculator shows me apx 26' of total head pressure. goal is at least 4 times overturn per tank, prefer 5-6.
Plan was to run two 3/4" return lines from the iwakis to the tanks and then y one line under the 75g and run it to the 25g (they are next to each other at a 90 degree angle and currently share a sump under the 75g). The pump feeding the 75/25 is planned to plumb into a manifold that will run a 35g frag tank and a 35g fuge. Since doing some research, plan changed to running 1" till ys.
Drain: this is where the questions really come in (again, unless something I have already described should be changed in some way). The original plan was/is to run a single 1" schedule 20 down from the 125g and also from the 75/25 (having them y'd together just behind the 75g) and then having the two main return lines y'd together apx half way and continue to sump as a single 1" drain. This idea was given to me by a plumber, not a hobbyiest hence my reason for asking here. He stated that by remaining at 1", I would reduce the "toilet flushing" sound.
Any help would be greatly appreciated as its time to start ordering pieces. Please and Thank you.
