Hi All, About a year ago I renovated my main floor washroom. Installed new American Standard Cadet 3 toilet. Over the last year I've had to auger out my main sewer line 3 times because toilet is not moving waste with enough water. I did have the line scoped with a camera just to make sure it wasn't a piping issue. Just seems like 4.8 liters is just not enough water each flush to keep things moving. Tank level is maxed out. Flapper has 3 settings but don't quite understand what each one does when moving chain? Will moving to a 6 liter make that much difference? Does anyone have any suggestions before I rip this out and buy a different toilet? Thanks for your help.
