Fman - thanks for the great write-up, I've got my account setup with wakemakers and am filling the cart for the order.
A couple things got me thinking, both regarding venting the bags
1. I wonder if all three bags could be tied in to one check valve/vent line. It seems like it could work since it's just air getting pushed out, although, what would keep the bags from venting in to one another. And for that matter, if a bag over fills and tries to push water out the vent line it may just end up filling another bag. Suppose I just talked my way right through that thought..... thanks for listening
2. If the bag is being vented, is there still a need for the anti-siphon loop on the fill side? The anti-siphon valve is basically there to create an air gap in the system so water won't be pushed/pulled in to a closed system. So, in essence, couldn't the "air gap" be located anywhere on the system? ie: bag vent located above draft line? Although, the anti-siphon loop helps prevent back-draining of the bag.
Certainly not trying to reinvent the wheel here, just some random thoughts I had.
Here's what I've got in my cart,
