Does anyone have experience with the macerator not pumping the contents out of the tank in a Gulfstream 232?
I have an '04 GS 232, it had the original Sealand 960 series Sanipot, with the holding tank plumbed to a Y-valve for overboard discharge through the macerator pump or to a deck pumpout. When I have Y-valve to overboard discharge and run the macerator pump, i hear it running but it's not pumping anything. I went and replaced the macerator pump thinking the impeller had gone bad, and I replaced the original Sealand 960 sani-pot with a new Dometic 960 sani-pot (same model, just brand new). I filled the holding tank with water and hooked everything up, but still not pumping material out of the tank. With boat on trailer, I can feel air blowing out of the through-hull discharge.
I think disconnected the pickup 1 1/2" line at the sani-pot, and stuck a hose in there and sprayed it while running the macerator and the pumped picked up a prime and sucked out all the water i was spraying in with the hose. I hooked it back up to the sani-pot tank, and it wouldn't pump out. Anyone have any ideas for me to try?
