American Standard 7381205-400.0070A – Frequently Asked Questions
1) Will an American Standard 7381205-400 flush valve fit my toilet if the tank opening is 2 inches?
No. This is a 3 inch flush valve assembly, so it needs a tank with a 3 inch flush valve opening and the matching 3 inch flapper seat. A tank drilled for a 2 inch valve will not take it. Measure the inside diameter of the seat at the bottom of the tank before ordering; 2 inch and 3 inch are the two common sizes and they are not interchangeable.
2) Does this American Standard dual flush valve work on a one-piece toilet?
It's built for two-piece toilets, where the tank bolts to a separate bowl and the valve is installed through the tank bottom with a shank washer and locknut. One-piece toilets use their own valve assemblies, so this one isn't the part for them.
3) What part number do I order for the American Standard 3 inch dual flush valve for two-piece toilets?
The manufacturer part number is 7381205-400.0070A. That is the full assembly, not just a flapper, so it covers the valve body and seat as a unit rather than a seal-only repair.
4) What is a dual flush valve and is it worth swapping my old single flush valve for one?
A dual flush valve gives two flush volumes off one valve, a short flush for liquid waste and a full flush for solids, instead of one fixed volume every time. It only works as a system: the tank, the trip lever or push button, and the bowl have to be designed for dual flush. On a two-piece American Standard toilet already built as dual flush, this 3 inch assembly is the direct replacement. If your toilet is a single flush model, a dual flush valve is not a drop-in upgrade, and you want the single flush valve that matches your tank instead.
