Once complete just remove the box (maybe cut away the epoxy??)

just my 2 cents...

Yeah that could work.

I also just realized that since it is a closed loop, I could actually plumb the whole thing and then just uncap the intake and allow water to drain...there is nowhere for the water to go since its a closed loop
