Okay, so I thought this would be a great buy, because it collapses, and it is Coleman brand. I was wrong. So, so wrong! There is no pressure release valve on this water carrier, so guess what, the water just very, very slowly goes out the less water you have in it. Yeah, I could have manually released the pressure by setting it right side up and opening up the valve, but then what is the point? I was super glad we had others to use instead of this piece of junk.
