Bought the ultramax for a powder room remodel on our newly purchased second home. Was very excited and did not mind spending more to get better. Researched til I was blind and decided on the ultramax based on this website's customer feedback "only one flush required" "no victory lap" "handles even the toughest job in one flush" blah blah blah. This toilet's flush does no better than the (much less expensive) kohler I have at my primary home. Even the most insignificant "deposit" leaves marks in the bowl that necessitate a second flush EVERY TIME. How disappointing! My husband has not even put it to the challenge yet.... that will probably require at least 3 flushes!!! Any advice out there? Already adjusted chain and water level to get max water flow during flush-no better. Also checked the stamp in the tank to verify they sent the right model. Argh.
