Last weekend my macerator pump locked up. It would draw about 50 amps (normal is about 20) when I turned it on and then trip the breaker.
Replacing the pump isn't a chore to be taken lightly, so I tried a few tricks first before pulling and replacing it and one worked.
I first pulled off the discharge hose and while a bit of s*** dribbled out from the holding tank through the pump. I tried to work a screw driver down in and wiggle the impeller. I coulnd't tell if anything was moving when I did this, but the fact that stuff dribbled back out told me that it wasn't a clog of toilet paper or ???. But when I tried the breaker again, same thing.
So I clipped the connectors near the pump and then reversed the power leads. The pump buzzed but didn't move when I applied power. I thought that this was a dead end, but when I rehooked up power with the correct polarity, it worked.
But who knows for how long.
