“The American Standard Champion is the only toilet I will buy. In different houses I have had several over the course of about 6 years. They do not clog, period. I used to only buy the “Champion 4” from Lowes, but it is no longer sold. The regular “Champion” does not clog but the flush is weak because the flapper is weird and they are trying to save water. This fixes it and gives it a super flush. I know it uses more water now—quiet down, I do not care.”
“Easy to replace per instructions. Great value for the price. Hasn't leaked since it was installed. The 3" size can't be found at the box stores. Functions as advertised!”
“I thought the fill valve was the issue, but it turned out to be this. Replaced the flush valve with this kit—came with all parts needed. Flushing is now quiet and smooth. Very happy with this.”
