I have two Zoeller M53 AC pumps setup in a primary and backup configuration. I added the Zoeller Aquanot 508 battery backup pump to the main pump.
Do I want to position the backup float so that the backup AC pump will activate first in the event of the main pump failure? My understanding is the Aquanot DC pump only runs on battery, so in the event of a main pump failure I’d want the backup AC pump taking over and the DC pump should only activate in the event both AC pumps fail or we lose power.
