Friends don't let friends buy an American Standard Champion toilet.
We went to our local independent plumber's showroom in town and asked for a toilet with these features -
The last thing we were concerned about was cost. We were trying to get over The Toilet From Hell so we wanted the best. The guy on the desk showed us the Champion and said it was the best flusher and quiet. We bought it and I installed it myself. It was expensive.
Then our nightmares really started. Whoever designed that tower flush valve should be taken outside, tied to a tree and shot 3x.
You press the handle. IF the little plastic pawls grip the inside of the tower the damn thing comes up with a big "CLICK" followed by a house-wakening "CLUNK" as the tower drops and then the sound of a jet plane taking off as the syphon action (enough to flush a fur coat or a double sleeping bag) scares the hell out of you and wakes our deaf cat.
Guests would come out of the bathroom and ask (wide-eyed) "What the hell was that?"
But sometimes (maybe 25% of the time) the pawls wouldn't grip the tower and you'd press the handle and you'd almost go on your head as there was nothing there.
We stuck with this monstrosity for a few months until we couldn't take it no more. This thing was landfill unless they would replace it with something else.
Long story very short - the dealer we got it from admitted he'd never seen or heard one in action so he had no idea about its noise and intermittent performance. He couldn't (wouldn't) give us a credit but he phoned A/S for us and left a message for them to call us. They never did. Finally I got hold of them myself and told them of this noisy, junk toilet. I told them that we'd asked for a "quiet" toilet and had been sold this thing.
The lady thought she had me as she claimed "We don't advertize this as a quiet toilet!"
I had her by the b@lls as I said "I have your brochure in my hand and it SAYS "This toilet is so quiet that you can say goodby to waking everyone up at night with noisy flushing". She fell silent.
She then offered me any other toilet in their line and they would send a plumber 90 miles one way to install it for me and take the other one away. That's what I was after!
We chose their Cadet. Two weeks later a plumber arrived and removed this monstrosity and replaced it with the sweetest crapper we can image - the beautifully quiet Cadet. Get one!
The Champion was not American Standard's finest hour.
