What Is a Macerating Toilet?
When flushed, a normal toilet sends waste through a trap, into a waste line, and onto the main drain line to the sewer or septic tank.
Because that drain line is below the level of the toilet, gravity pulls the contents of the waste line into it. It's the same with sinks and tubs.
Macerating toilets (aka "upflush toilets"), on the other hand, send waste to a macerating unit located behind the toilet or in the wall. High-powered blades liquefy the waste, which is then pumped out of the unit through normal pipe that's been tied into the main drain line.
Macerating toilets are more expensive than standard ones, but connecting a small-diameter pipe to an existing system is much easier and far less expensive than redoing the whole thing.
