Macerator Pump Leaks
I have a 2010 AI 3500 and the flojet model 18550-000 macerator pump has sprung a leak. When I open the blackwater or graywater valves to pump out I get a steady drip from somewhere in the pump body. Flojet sells a service kit with new gaskets, pump body, impeller etc and I would order one but I would like to remove pump from it's mounting and inspect it to see exactly where the leak is coming from first. And herein lies the problem. The studs that hold the pump to it's mounting bracket are welded to the bracket and the self-locking nuts that hold the pump to the studs cannot be reached with a wrench of any kind (they are underneath the pump buried in rubber, shock-proof mounting material). I looked at removing the pump mounting bracket but it seems to be fastened to the sprinter frame with some kind of rivet. Does anyone have experience removing a macerator? I sure could use some help on this one.
