Can an American Standard Champion 4 be converted?

[Mark SC]

I bought and installed an American Standard Champion 4 with the 1.2 (?) gallon flush. I'm not happy with it because the flush valve needs changing and it doesn't have enough flushing power. I was going to change the flush valve but the fill hose is a different size than the universal kit uses, which I can always find a piece of hose that will work. I won't to convert it to a 1.6 standard flush if possible. Is there a kit out there to change it? There is at least 3" of water under the flapper that is not being used. Any help would be appreciated. I really don't want to buy a whole toilet if I can avoid it.

Changing the seal.

If this is a two piece toilet where the tank bolts to the bowl there is a solution.
Korky makes a 3" flapper flush valve replacement that works on the Champion.
I would pick up their kit that has a fill valve by Korky too. You will then be able to use more of the water in the tank.

So..., basically, I have to take the tank completely off before installation of this kit. I thought it came with a 4". I could be wrong. I'll admit I haven't taken a close look, but I will when I get home. Thanks for the response!

I just realized there's another whole forum for toilets.

They call it a 4 but the outlet is a 3"
This tower is so tall that it leaves a lot of water in the tank.

Here is a Champion flush valve. The flapper sits pretty high in the tank.

How to replace the seal.

It will require removing the tank, right?

Never mind. The answer is yes. Just two bolts.

Check to see if it has an adjustable flapper. My cadet pro had a adjustable flapper and after adjusting to max it works perfect. Never have to double flush.

Champion has a universal flush valve that you can set to 1.28 to 1.6. Part #3174.105-0070A. You will also need the tank to bowl kit # 738756-0070
