American Standard R433 – Frequently Asked Questions

1) Does the American Standard R433 diverter valve come with a handle or trim?
No. The R433 is the rough-in valve body only, sold less handle, and the trim has to be ordered as a separate item. Plan on specifying the trim kit and handle at the same time you order the rough so the finished wall matches the rest of the bath.
2) What size pipe connections does the American Standard R433 rough-in valve take?
All ports are 1/2 inch NPT, inlets and outlets alike. That means threaded iron pipe connections, so copper or PEX runs need the appropriate 1/2 inch NPT threaded adapter at the valve.
3) Can the R433 diverter run two shower heads at the same time?
No. The R433 is a 3-way diverter set up for 3 discrete functions, meaning it sends water to one outlet at a time and does not allow shared flow between shower outlets. If you want a rain head and body sprays running together, you need a diverter configured for shared functions instead.
4) How many outlets does the American Standard R433 in-wall diverter control?
Three. The valve switches water between three outlets, which can be shower heads or spray sets, plus the single 1/2 inch NPT supply inlet. It is the in-wall body that does the switching; the visible handle and escutcheon come from the trim kit.
5) Is the R433 valve body brass or plastic?
Cast brass. American Standard built the R433 body in cast brass for high-use installations and prolonged contact with water, which is the reason it turns up in hotel, multi-family, and other commercial shower work rather than plastic-bodied residential diverters.
6) Is there ADA compliant trim available for the American Standard R433 diverter?
Yes. American Standard offers a wide selection of ADA approved trim for the R433 rough-in, which matters if you are specifying for healthcare, education, hospitality, or any accessible guest suite. The trim is a separate order, so the ADA selection is made at the trim level, not at the valve.
7) Why does the R433 rough-in valve show no finish option?
Because the R433 buries in the wall. It ships as a single unfinished cast brass body with no decorative plating, so the only finish decision on the job is the trim and handle you pair with it. Nothing about the rough changes from one bathroom finish to the next, which makes it easy to standardize across a whole property.
8) What is the American Standard part number for this 3-way diverter rough-in?
The manufacturer part number is R433. Ask for it by that number when matching an existing installation, and specify the trim kit separately since the rough carries no handle.
