Hello all. Had a puzzling question regarding our macerator. We installed it new about 7 years ago and directly draws from the house battery circuit. It might be used 3-5 times per year on average. Last year, in year 6 or so, it seemed to get weaker and on occasion, it would not run at all and sometimes pop the breaker that we installed for it, when trying to empty a full black tank. After turning the shaft screw with a screwdriver, it would run for a bit, then shut off again. Turning the screw again would get it going again and the process would repeat. We've also tried with the engine running, and also hooked to shore power, which seem to help a little but on occasion we still need to use the shaft screw.
So now I'm wondering if we are needing a new macerator, or if this is normal as the pump ages. I know the model we have (Jabsco) has dry run protection which appears to work when we are on shore power, as it shuts off when the level is low (after I rinse out the tank a few times with the wand).
My next step is to possibly replace our house battery as it is 7 years old and also seems to be getting weaker and is starting to swell at the terminals. At first I thought the macerator issue was only on battery but even on shore power it still isn't 100% working.
I know this may not be an easy answer but looking for suggestions, thank you!!
