Whale Gulp Macerator

[boatlover14]

The macerator does not seem to be making any noise. I replaced the fuse, and that is fine. I checked the wires and they are fine Is it just quiet unit, or what else should I check

Does it pump the tank out?

They aren't all that quiet when they're running. Try taking a battery and jumper cables and applying 12 volts directly to the motor leads.
