I got here at the farm at some point in time about an hour ago. I found the water pump for the aquaponics tank to be in a failure mode so I proceeded to troubleshoot. My first assumption was that the float switch had tripped, but on resetting the motor still did not resume. Next I disassembled the motor and found that the rubber impeller had melted, and the motor was seized. I cleaned all of the rubber residue and installed a new impeller. While these repairs were in progress, I added water directly to the fish tank.
