American Standard 3280.040-0070A – Frequently Asked Questions
1) Will the American Standard 3280.04 flush valve fit a two-piece toilet?
No. The Champion 4 flush valve assembly, part 3280.040-0070A, is for American Standard one-piece toilets. A two-piece tank uses a different valve and tank-to-bowl arrangement, so you need the repair part matched to that model instead.
2) What part number do I order for a Champion 4 one-piece toilet flush valve?
Order manufacturer part 3280.040-0070A, the American Standard Champion 4 flush valve assembly. That is the number to give a parts counter or match against the old valve.
3) My Champion 4 toilet runs constantly. Do I need the whole flush valve or just a flapper?
The Champion 4 uses a tower-style flush valve rather than a conventional flapper, so a generic flapper will not seal it. When the seal has gone, the fix is the complete 3280.040-0070A flush valve assembly for the one-piece Champion 4. If the water is running into the overflow instead of past the seal, the fill valve is the culprit, not this part.
4) How big is the American Standard Champion 4 flush valve assembly, and will it clear a tight tank?
The assembly measures 10.2 x 7 x 6.3 inches and weighs 0.882 pounds. Those are the outer dimensions of the complete valve tower and flapper unit, so allow that much room in the tank when you set it in and check the overflow tube height against the old part before you cut anything.
5) Is the 3280.04 a repair part or a complete toilet?
It is a repair part, not a fixture. The 3280.04 is the flush valve assembly only, the tower and seat inside the tank that releases water to the bowl. It does not include the tank, bowl, fill valve, or trip lever.
6) I manage a building with several Champion 4 one-piece toilets. Can I stock this valve as a standard repair item?
Yes, that is exactly what it is for. Part 3280.040-0070A is the flush valve assembly for American Standard Champion 4 one-piece toilets, and it is a single, unfinished part with no handing, size, or color options to sort through, so one stocked item covers every Champion 4 one-piece in the portfolio.
7) Is the Champion 4 flush valve a finished part I need to match to my toilet color?
No color matching needed. The Champion 4 flush valve assembly ships unfinished, as a NO FINISH item, because it sits inside the tank where nothing shows. Only the trip lever and seat would need to match your trim.
