In the process of putting this system together. One modification is I'm using a flexible rubber coupler on the Exhaust instead which eliminates the need to sand out the PVC coupler for fit. Also adding a second tub for a Shaft catch basin as well to eliminate as much waste as possible.
I'll make sure to take pics as I get it all put together.

Deerfield,
Is that just Hot Tub hose you have running from the catch basin to the intake? How much (length in feet) do you suppose you have?
