Installing a new bathroom in a basement can be a major undertaking.
The concrete floor must be broken into and drainpipes installed, then new concrete must be poured.
An upflushing unit makes the job much easier.
A 3-inch vent is required.
confirm the vent and drain conform tolocal plumbing codes.
Some upflushing units, especially those installed in the ’70s and ’80s, were unreliable and needed frequent repairs.
Newer units are more dependable.
Ask a plumbing supplier about the track record of the model you are considering.
An upflushing unit has a heavy-duty pump activated by a float and switch.
A 3-inch vent is required.
verify the vent and drain conform to local plumbing codes.

A macerating toilet has a rotating blade that grinds waste before pumping it away.
Macerating units have smaller discharge and drainpipes.

A macerating unit must be connected to a horizontal outlet toilet.
Some manufacturers combine a toilet and pump.
you could choose between stand-alone macerating toilets and units with connections for a tub/shower and a sink.
