American Standard 6147SM121.002 – Frequently Asked Questions

1) Will the American Standard Ultima 6147SM121 flush valve fit my toilet's spud?
It's built for flushometer bowls with a 1-1/2 inch (38 mm) exposed top spud. If your bowl has a back spud, a concealed spud, or a smaller top spud, this isn't the valve for that opening. Urinals are out too, it's a toilet (closet) valve at 1.28 gpf.
2) What rough-in does the Ultima 6147SM121 sensor flush valve need?
The valve is set up for an 11-1/2 inch (292 mm) rough-in, measured from the centerline of the supply stop to the centerline of the bowl spud. That's the standard commercial closet flushometer rough, so it drops onto most existing water closet supply layouts without moving the stop.
3) Does the Ultima touchless flush valve need power wired to it, or does it run on batteries?
Battery powered, and the four C-size alkaline batteries come in the box. No electrician, no transformer, no conduit to the stall, which is why these get specified for retrofits in occupied restrooms where running low voltage to each fixture isn't practical.
4) Can someone flush it manually if the sensor doesn't pick them up?
There's an override button on the valve, and it's electronically operated rather than a mechanical push. Press it and the valve cycles a flush. Useful for housekeeping staff walking a restroom and for the occasional user the sensor misses.
5) Is the 6147SM121 a diaphragm valve or a piston valve, and does that matter for my water?
Diaphragm type. The diaphragm uses American Standard's EvoLast material, which is made to resist chlorine and chloramine so it doesn't harden and fail early, and that's the usual reason diaphragm valves need rebuilding in municipal systems with heavy chloramine dosing. The body is a proprietary brass alloy that resists dezincification.
6) We have flush valves that keep running on. Does this one address that?
That's what the DynaClean feature is for. An integral wiper spring scrubs the refill orifice on every flush, so sediment and scale don't build up in the orifice and hold the valve open. Run-on is almost always a clogged bypass orifice, so this is the mechanism aimed directly at it.
7) Does the Ultima 6147SM121 meet a 1.28 gallon water use requirement?
Yes, it flushes 1.28 gpf (4.8 Lpf), the standard high-efficiency closet volume. Pair it with a bowl rated for 1.28 gpf; dropping a 1.28 valve onto a bowl engineered for 3.5 gpf will underperform on carry.
8) What finish does the American Standard Ultima sensor closet flush valve come in?
Chrome, ordered as part number 6147SM121.002. That's the single finish on this model, which is what most commercial restroom specs call for anyway.
9) Is this valve suitable for a busy commercial restroom or is it a residential product?
It's a commercial product, part of American Standard's Selectronic diaphragm flushometer family for toilets. Touchless operation is the draw in high-traffic public restrooms, schools, and healthcare, where limiting hand contact on the fixture matters as much as the water savings.
