American Standard 7301476-100.0070A – Frequently Asked Questions
1) What does the American Standard 7301476-100 coupling kit actually do on a toilet?
It is the coupling kit that joins the tank to the bowl on American Standard H2 Option and other dual flush toilets. American Standard catalogs it as an adapter-type coupling for toilet applications, so it is the hardware between the two china pieces, not a flush valve or a fill valve.
2) Which toilets does the American Standard dual flush coupling kit fit?
American Standard specifies it for the H2 Option line and other American Standard dual flush models. If the toilet in front of you is a single flush model or another brand, this is not the kit for it - match the coupling kit to the tank the manufacturer built it for.
3) What part number do I order for the American Standard H2 Option toilet coupling kit?
Order by manufacturer part number 7301476-100.0070A. It ships as a single configuration with no finish option, since the hardware sits inside and under the tank where finish does not matter.
4) I manage a building with several American Standard dual flush toilets and the tanks are weeping at the base - is a coupling kit the right repair?
If water is showing up between tank and bowl rather than at the supply or the flapper, the tank-to-bowl coupling hardware is the usual culprit and this kit is the American Standard part for H2 Option and other dual flush units. Standardize on one kit across those openings and you can stock a single part number, 7301476-100.0070A, for the whole fleet. Leaks at the base of the bowl itself are a wax ring issue, not this part.
