I hope to be plumbing 2 750 lb V drive bags and a 650 lb integrated bow sack and am trying to outline the budget for the system so I can have a savings goal. I'll probably end up having to plumb in a 350 lb tube in the ski locker if I want to completely fill the 750s for wakeboarding but that might be phase two.
Through research on here and other sites I've decided to go with aerator/livewell/cartridge pumps (Whatever you want to call them) vs. impeller pumps mainly because they're cheap and easily replaceable. I considered the Simer pumps but the lack of ignition protection and the high startup current requirements were turn offs. The Ballast Puppies and what not seem great but I just can't spend that kind of money even though you do only need 1/2 of the quantity of pumps due to their bidirectionality.
On the fittings I've never seen one of these fly high bags in real life. I see that they have 3 connections (2 on top and 1 on bottom in the pics) but only one top one looks like it includes a threaded quick disconnect. I assume that if you want to plumb a drain line and a vent and want to retain the ability to quickly disconnect it you'd need 2 more threaded quick disconnect fittings for each bag. It looks like you can get the Fly High ones or the Flow Rite ones. Is there any advantage to using one over the other? The Fly High ones are more expensive unless I'm looking at the wrong parts.
Also, I see people recommending connecting the drain pumps straight to the bags. This seems like it would work fine on the V drive bags where there's a lot of space for the pump but I was wondering about the integrated bow sac. It seems like the pump would get pushed up against the seat bottom. Didn't know how that would affect pump performance/life. Is it common to just mount the drain pump below so that the water flows down into it?
So, for each bag the best I can figure is this:
1 of these for the drain pump- http://www.wakemakers.com/fly-high-p...ting-w734.html
2 of these (Fill & vent hose side)- http://www.wakemakers.com/fly-high-p...ting-w738.html
2 of these (Fill & vent bag side)- http://www.wakemakers.com/fly-high-p...ting-w730.html
Would that be correct? Any better/cheaper way to do it other than eliminating the quick disconnect functionality? Can anybody comment on quick disconnect functionality and whether it's worth doing? By the time I add hose, thru hulls, check valves, misc. fittings, switches, wiring etc this isn't going to be cheap at all.
