Can the tank of a Flash Flood cave in with an AquaPak?
Yes. If both the AquaPak and Flash Flood reservoirs are filled, there is no air to refill the Flash Flood reservoir as it drains. Once the AquaPak is empty, the Flash Flood reservoir will begin to collapse in on itself because there is no air to replace the water leaving the reservoir. The simple solution is to remove the AquaPak once it is used up.
