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)
