Drain connection to existing system #2

We have a macerator for our downstairs unit, which we didn't know would be a big issue, however, since we moved in early this month to our first home it is making a lot of loud noise which is unbearable for our flatmates and us. We are considering putting a new sewer drain for the downstairs unit or connecting it to the old system. We don't want the macerator pump. Any help would be great.
