American Standard 624B721.002 – Frequently Asked Questions

1) How much water does the American Standard Ultima Selectronic 624B721 flush valve use per flush?
It's a dual flush valve: 1.28 gpf (4.8 Lpf) for the full flush and 1.1 gpf (4.2 Lpf) for the reduced flush. That makes it a match for water closets rated at 1.28 gpf, and the reduced-volume flush is what the sensor delivers on a short use. If your fixture is spec'd at 1.6 gpf, this valve will under-flush it.
2) Is this a urinal valve or a toilet valve?
Toilet only. The Ultima Selectronic 624B721 is built for water closets, and its dual 1.28/1.1 gpf volumes are toilet volumes. Urinals run far lower volumes and take a different valve, so don't cross them over on a retrofit.
3) Does the 624B721 mount exposed or behind the wall?
Exposed. The valve body, sensor, and vacuum breaker all sit in front of the finished wall where they can be seen and serviced without opening a chase. If the specification calls for a concealed valve with only a sensor plate showing, this isn't the one.
4) Is this flush valve rated for a school or office restroom, or is it a residential part?
It's a commercial part. American Standard groups the Ultima Selectronic diaphragm flush valve line as commercial, non-luxury, which is the specification tier used for schools, offices, and other high-traffic public restrooms rather than a home bathroom.
5) What does the "base model" designation mean on the 624B721?
Base model is the entry configuration of the Ultima Selectronic exposed diaphragm valve family, with the sensor and dual-flush operation and without the added options the higher configurations in the same family carry. If you're standardizing a floor of restrooms on straightforward sensor flushing at 1.28/1.1 gpf, this is the plain version of that valve.
