View Full Version : Stacking fat sacs

Is it OK to stack a fat sac on top of a filled factory locker bag? Would that just be asking for trouble?

Two things to consider: 1. Are you going to hurt the sac below? Doubtful. These things are really tough. 2. Can the space support the weight? You have seen posts with guys reinforcing locker walls, etc. You don't want to blow out the ski locker walls or something. Anyway, if that wasn't a concern or you were able to reinforce I see no reason why you couldn't do it.

I stacked either one or two 400 lb sacs on top of a 750 all year last year.
At some point the weight on top is going to put enough pressure on the bottom (factory) sac to make it leak out the thru hull.

i stacked 2 250's prior to getting my 750. No problem.
my 750 is pushing water thru my drain pump, so i installed a valve. I'll just have to check it to see when it is full. I've found a PVC valve and nipples @ Lowes so I'm looking at about $7/valve. I've got multiple set-up configurations i can run now for filling & drainng, w/o breaking the bank. May not look the greatest, but it work well!
