Took the cover off, and I do have two pumps with two switches
Power to the outlet is fine
Yes, it is battery backup........
The backup pump and pump switch does not have a plug, it is wired directly into the backup panel
The main pump and main switch have a plug..........I plugged the switch in, plugged in a lamp, and lifted the switch. The lamp turned on
I then plugged the main pump in and can definitely hear and feel it hum.......how loud should it be?
Everything was coated in sand, some thick and some areas barely any
I will go test the back up battery
