The American Standard Mainstream 753AA101.020 is part of the Toilets test program at Consumer Reports. In our lab tests, Toilets models like the Mainstream 753AA101.020 are rated on multiple criteria, such as those listed below.

Solid waste removal: A high score means the toilet effectively and consistently evacuates various types of solid waste from the bowl through the trapway and into the drainage system. A top-scoring model delivers a strong flush that helps prevent clogs and reduces the need to plunge.

Noise: Flush quietness without the seat.

Bowl cleaning: A high score means the toilet flushes away more waste from the inner surface of the toilet bowl, particularly the front and side walls where residue is most likely to remain. A top-scoring model stays cleaner with less scrubbing.
