Remote water tank pump shut off Answered
The community has a water tank on the top of the hill and a pump about 1/4 mile away, nearly line of site. There is a float in the tank that used to send a signal down a wire to shut down the pump when the tank was full but the wire has since corroded and is no more. They do not want to run another cable. We are thinking that a solar powered radio transmitter at the tank could operate a shut down receiver at the pump. (The pump has AC power but there is no power at the tank.) Anyone have any ideas how to make this work?
