Well.. I hit a roadblock tonight with my return plumbing... I over looked how long the final section, with 2 ball valves to control the return bulkheads flow, a reducer T... in short... my bulkhead holes weren't drilled wide enough apart and I can't fit the T with ball valves between them...
Hmm.. gotta figure something out now..
I pretty much copied fishytime's plumbing...
I got one idea, and that is to T it off down lower, to 90 corners, run the ball valves vertically, and then 90s into the 90's at the bulkheads... but worried its going to affect my flow too much with the 4 extra 90's.
