Here's some pics of the equipment and plumbing.

Overlflow box single 1" return split with a T to fuge and bubble trap in skimmer section. There are valves on each line to control flow.

From left to right it goes return line, return #1 closed loop, intake for the loop, overflow and finally return #2 closed loop. Return line is 1" with a valve and the closed loop is 3/4" with a valve on each return.
