From the picture, I can't tell for sure where you think the leak is coming from..... does it appear to be coming from the glass portal on the bottom of the macerator, or from one of the rubber connecting hoses. All the fluid passages in and out of the macerator have heavy rubber sections secured with hose clamps. Can you see the origin of the leak?
If it appears to be leaking from the glass port in the bottom, that port is sealed with several "O" rings and a series of screws around the port and "O" ring. Sadly, you cant get to any of those screws with the unit still installed.
I also assume that you have tightened down the screws in all the hose clamps to make sure that they are not just getting loose.
