I am thinking of adding a water cistern/tote into my garage (approx 250 gals or maybe stack 2 for 500 gals or so), just to have some water for washing my hands kind of thing. Also, it would be nice to have, say a 50 ft garden hose connection too. Would a 12 volt RV pump be enough to provide pressure through the garden hose, or are they meant for shorter runs? If the rv pump won't cut it, would I have to get a jet pump and pressure tank kind of setup? I don't think I will have a water heater, but I may add a 6 gal electric one, just to have some hot water if I want it. Any suggestions or ideas are welcomed!
