It's hard to tell from your description, or maybe just hard to believe, but if you are using the water jugs to support a significant amount of weight stacked on top of them, that is the problem (not the container itself). It sounds like you are looking for a sturdier water container, and that is always a good idea, but when you settle on one, try to store it so the valve or opening is on top, near or above the water level (that may be up-side-down) and don't compress the container by putting anything on top of it. If you must stack supplies or furniture over it to conserve space, build a rack over the containers that will support the weight and leave the water containers protected from compression.<br>
