Can I use these to, effectively, hold water? In the long term.

I use it for gas and it holds well. I don't know if it rusts with water or not in the long run, but it holds liquid gasoline.

You probably could but I would use a plastic container as the metal will effect the taste if you want the water to drink. But for non consumable water it would be great, a little pricey though...

To answer your question I am not sure but think about this. These cans come from China so who only knows what is in this metal. It looks like bare metal inside the can or some sort of clear coat(China not known for their environmentally friendly paints and such). I would not if I were you.

These are designed for Gasoline and diesel fuel storage...I would recommend a container designed and certified for storage of water....

They should hold water well for the long-term and short term but it may not be fresh if held for a long time

I use them with a drysuit when kayaking with cuffs over and cinched. They are not dry but limited leakage When immersed when entering or exiting boat. Constant and prolonged immersion may pose a problem.

I haven't had anything leak through when using them... They hold a lot more than you think they would.

No...they are essentially made out of tissue paper so water would damage them.

Yes, I'm sure they would be okay in water. They are elastic bands with a plastic button.

Yes... That's what I use them for. There good for both salt and freshwater.

Yes they will float for a while. Don't leave them in the water for a long time.

I suppose you could but staying watertight over the longterm may be a problem. They seem to be sealled pretty well but I would defer to the manufacturers opinion for this use. They would look cool while they lasted anyway...

I think that you could stack them...but I doubt that they would hold against the pressure of 24" of water. You probably need sandbags. These Quick Dam barriers are good and hold a lot of water for a long time. Ours are still intact and in place after 8 months. (Although we haven't had any torrential rain here in Central Pennsylvania for some time) I'll be very interested to see just how long they will last.

They probably can as the ball portion of these are only a little larger than a quarter so if you can get that size into your water tank they should work.

I don't believe so. I couldn't do it, and not just that but I wouldn't even waste your money or time on these. They eventually get water in them and you can't get the water out. The old water that gets stuck in there starts to make the inside rust. I threw mine out.

I used them inside beer bottles and they seem to hold, however , I soaked them in water first to help swell them before adding liquid.

Not a good idea. It does tend to get water in them when a stream of water is around. When it rains not really. Only when a constant stream of water is around you tend to get water in them

I don't see why not...they're just plastic....water shouldn't affect them...

I would think you could. They work very well and are lightweight to move. They do stay filled quite a while once activated and you may need to adjust how they are stacked to balance. They keep the water well away from your house during flood weather.

Yes sure. In fact, I think they would last longer if not floating in a pool. I keep mine in the pool all the time now though.

Yes, soak them and then run your fingers down them to squeeze out the excess water. They work great!
