I received the following E-mail from Pamela Kay Director of Communications at Family Motor Coaching, FMCA.
She also included a response from Arthur Vaughn a FMCA member, thought I would share Arthur's tip regarding Macerator Pumps with all.
Hello, Ron. Your letter about the issues you were experiencing with the macerator pump in your Roadtrek motorhome appears in the February 2012 issue of Family Motor Coaching magazine. I am hoping that since you wrote to us in the spring, you have resolved your concerns and are enjoying trouble-free motorhoming. But just in case you are still experiencing difficulties, below is a response we received from a fellow member offering some tips.

I have used a macerator for several years. First, make sure you are not skimping on the use of water in the black tank. Second, open the gray water valve to pre fill the inlet to the macerator. Third, close the gray water valve and open the black water valve. Forth, turn on the macerator. When the black tank is empty, turn off the macerator, leave the black valve open, and open the gray water valve. This will let soapy water flow into the black tank, wait a minuet then close the gray valve.
Turn the macerator back on and re-empty the black tank. Do this 2-3 times. Then close the black valve, open the gray valve and turn the macerator on and finish emptying that tank. This will clean the macerator impeller and be ready for the next time.
I don't think gravity has a lot to do with the problem Ron is having do to the fact that the macerator is generating a great suction when running, thus, make sure pump is NOT running when valves are closed.
I think the fuse blowing problem is from material left in the impeller and it is solidifying. Macerators have a hole behind the motor with a screwdriver slot in the end of the motor shaft. A short stubby flat bladed screwdriver can be used to turn the shaft, WITH MACERATOR SWITCH OFF, and free the motor, this should work if a fuse blows.
Works for me. Hope this helps.
