The AutoPot 13 Gallon FlexiTank revolutionizes water storage. It is everything you need in one compact box. It requires no tools for assembly, reduces storage and shipping costs, and takes minutes to assemble. It really couldn’t be simpler. Unlike other waterbutts and barrels, the AutoPot FlexiTank can be stored away when not used, can fit where other reservoirs cannot go, and is adaptable in ways standard reservoirs are not.
