American Standard Cadet Evolution Toilet. Sold at Home Depot
A kind of marginal toilet, at least the homeowner thought so.
Trapway of the Evolution.
Sue had installed this when she did her remodel five years ago. She installed two toilets from Home Depot. The other one was a Glacier Bay that she tried to return. The Evolution was better than that, but not much. We replaced this one with a Kohler Santa Rosa, and she likes that much better.
The Glacier Bay was replaced with a TOTO Drake II, which she calls "self cleaning" in comparison to the Glacier Bay.
