trying to get ideas

[Joker]

I'm doing my 3d model of my new frag systems and I'm having a hard time with split of return. Right now I'm thinking of using this piece https://www.lowes.com/pd/LASCO-1-in-x-1-in-x-1-in-x-1-in-dia-Side-Outlet-Elbow-PVC-Fitting/3344668 but I know that it would be a killer on the head pressure and shorten the pumps life. Maybe you guys can help with a better way to split it. Heres the 3d model so far ( the green pipe is the return line and there wont be 90 degree angles they will be 45 degree)

Place valves on both return pipes, one will always flow better than the other

I'm getting 2 gate valves

Ideas:

1. 2 separate return lines on separate pumps
2. Flex rather than hard plumbing using Y splits
3. 1 and 2 together
4. Silicone hose into Y then into hard line returns
