Macerator Pro&Con

Mostly positive stuff here so I will post a situation a friend had last year. He was using his and a wad of "something" hung up just ahead of the blender and nothing would pass. He tried moving the MH, a plunger, already near full tank, etc with no success. He had to call a mobile serviceman and it was a messy and expensive job to remove and replace the unit in order to remove the clog.

Just one situation I would prefer to avoid. I guess they do have advantages as many have stated if you have a need for lengthy or uphill disposal.
