My 2 overflows are separated. I don't think I can do the primary and secondary drain as you shown. If I'm using 1 drain on each overflow, is it going to work when I have a ball valve just above the water line.
Would it be better if I connect the 2 overflows into one, then split to my skimmer and fuge compartments with ball valve on both end?
Let me know if it isn't good enough to give you a picture of what I'm talking about. I'll try to get a diagram up this evening.
