I have a culinary well, rather than municipal water. As a backup water source, I would like to plumb a hand pump into the system inside the house so I can still get water in case of a power outage or other problem. The plan would be to plumb it in where the line comes in the house. Naturally there would also be a few valves necessary, one on the pipe to the hand pump, and another to block off the lines to the house and pressure tank. What I need to know, however, is whether I can pull water through the submersible pump in the well when it's not running. It seems to me I should be able to, but I'm not sure exactly how those are built so I don't know for sure. By the way, I do realize that hand pumps usually can't raise water very far, but that shouldn't be a problem. The water table is very high around here, and the water level in the well casing is only about 10 feet below ground level. The pump will be in the basement, so it will only have to raise the water less than 10 feet and pull it through 30 feet of pipe.
