It's a bit of an issue, if we get the Dart to run full capacity then likely your overflow will not handle it, I would plumb 1 1/2 all the way to the surface then tee off the 1 1/2 pipe to get a total of four 3/4 returns, send 2 to the bulkheads and the other two would have to go over the top. when it comes to volume you need four 3/4 outlets to handle that pumps capacity

you may have to throttle back the pump to keep the sump from draining, and the tank from overflowing

I will give this some thought.... thank you.

If you plan on staying bare bottom, the swap out the Dart for something around 800 to 1200 gph, throw the Dart onto an over the top closed loop, you can boil that tank.

Close Mr OM good catch, Each of the two 3/4 " lines need to come off the 1.5" pipe. I just noticed that it was reduced to 3/4" after the TU Ballvalve coming out of the pump. Sorry Prazil I should have caught that on your Feb. 26th update. LMK how I can help to switch it.
