I am really excited about how inexpensively I can add a SWG to our AGP! We currently run the pump from a timer located next to the electrical panel in the garage. It shuts the power off at the house so if I had a SWG out by the pump, it too would loose electricity. Is there simple/logical/reasonable way around this problem? Does anybody's have a 9v battery back up like my radio alarm clock in the house?
