Reading some tips this morning got me wondering how many people living in homes (bldg. or apt) that have hot water heaters. If that is you then go buy a short, cheap garden hose. When SHTF drain all the “cold” water you can. DO NOT TOUCH the hot water valve. Take your garden hose and screw it onto the drain plug of your hot water heater. Stretch out the hose to a desired length to fill any container you may have. Try to keep the length short as possible, cut off extra length.
