4. American Standard Champion

Pressure Assist Toilet American Standard Champion


The American Standard Champion is a one-piece toilet with a combined cistern. It is made up of vitreous china along with an Ever Clean Surface. The Ever Clean Surface is specifically designed to reduce staining and hinder the growth of mold, bacteria, and mildew. Consequently, keeping the toilet cleaner for a longer time.

Moreover, the combination of the levered flush mechanism, the seat’s height, and the bowl’s shape all make the American Standard Champion ADA-compliant.

Undoubtedly one of the best pressure-assist toilets has a single flush. The American Standard Champion 4 uses a flushing system that consists of a 4” non-adjustable piston with the Accelerator flush valve that delivers a high pressure 1.6 gallons flush. The 2 3/8” trap way of American Standard Champion 4 allows the waste to pass smoothly to the drainage system. Moreover, the flush system has been tested as capable of dispensing 2.2 lbs of waste in a single flush.

The American Standard Champion encompasses a high-pressure flushing system that ensures that the toilet flushes completely and properly in a single flush. The 1.6 gallons per flush assures that this toilet is within the Federal toilet flush specifications. However, the 1.6 gallons per flush means that it is outside the Water Sense guidelines and does not qualify for the exemption.

The toilet is designed to fit a minimum of a 12” rough-in. And as the American Standard Champion is a one-piece toilet thus, it is heavier than the individual parts of a two-piece. This weight makes the Champion a little more difficult to position over the rough out. Therefore, rather than doing it on your own, it better be done as a two-person job.
