Being in hurricane country when we get a storm power can be out for days. Does anyone have an economical solution to keep a water pump up and running till power is restored. This would have to be with no one home as most times we have to evacuate. something like a low amperage pump that would run on auto batteries for 3-4 days would be great. would not mind investing in 3 batteries or so and wire parallel to maintain 12 volts. Lets see what ya got. Thanks!!
