When it came time for the 6 month change-out of my emergency water, what a surprise to find how light the jugs felt! Both of my Reliance Products Desert Patrol 6 Gallon Traditional Jeep Style Rigid Water Containers had sprung leaks. Slow leaks, so I didn’t notice in my dry cool basement, but both were half empty. Okay, out they go! Then checking my Reliance Products Aqua-Tainer 7 Gallon Rigid Water Containers, one of them was light too, having sprung a leak some time in the not-too-distant past. One had a leak near the top from having the other stored on top of it – as is encouraged by the interlocking design, if not by manufacturer’s instructions. Once again, monitor your preps! – W.R.
