Ok so I am using this diagram as reference. I realize I do not need everything they have listed but I do plan on tying in the drain and vent lines together. My question is, if you have the Drain pump/line attached to the bottom fitting of the sac, wouldnt water continually drain out of the bag while under way? What is the point of the check valve in the vent line?
Wouldnt it be better to attach the fill line and put a check valve on that on the bottom of the bag so it doesnt drain out and put the Drain line/pump on the top of the bag? But would you have priming issues with that?
I am planning on doing a three bag system with a total of 6 aerator pumps so I want to get it right the first time. Let me know what works for your setups.
Oh and dont get started on "just shell out the extra dough and run a reversible pump" I dont wanna thats why.
