MDinana...that's what I do with the garden sprayer...

hikermor... I don't have room to hang the gravity bags in my shower...actually I have room, but I place a 33gal plastic trash can in the shower to hold non potable water, and my room is limited... the sprayer is convenient to mix, transport, and provide water pressure

after the long power outage in 2004, I did an after action debrief with my kids.... the lack of hot shower and batteries for their entertainment gizmos was the most common complaints... the trash bag was investigated for use by those in condo/apartments without access to garden hose...
