American Standard 6147161.002 – Frequently Asked Questions

1) What is the rough-in dimension on the Ultima manual toilet flushometer?
11-1/2 inches (292 mm) from the centerline of the supply to the bowl spud connection. That's the standard water closet flushometer rough-in, so it drops onto most existing commercial toilet supply stubs without moving the wall penetration.
2) Can this flushometer be mounted with the handle on the left side?
Yes. The Ultima manual valve installs left- or right-handed, so you can set the handle on whichever side clears the partition or grab bar in the stall. That matters in accessible stalls where the handle has to be on the open side of the fixture.
3) Is this flush valve ADA compliant for a public restroom?
The handle is an ADA-compliant non-hold-open design, shutting off automatically after every flush so no sustained force or grip is required to complete the cycle. Mount it on the open side of the stall to keep the reach compliant.
4) How many gallons per flush does the American Standard 6147161 use, and will it meet a water conservation spec?
It flushes at 1.6 gpf / 6.0 Lpf, the standard full-flush water closet rate. If a project calls for a high-efficiency 1.28 gpf valve or a dual-flush handle, this one won't meet that line item.
5) Should I buy a diaphragm or piston flushometer for a high-traffic restroom?
This Ultima is a diaphragm-type valve. Diaphragm flushometers are the common choice for commercial restrooms and rebuild quickly with a kit; piston valves are generally favored where water quality is poor and grit chews up diaphragms. American Standard's answer to diaphragm wear here is EvoLast material, formulated to resist chlorine and chloramine so the diaphragm doesn't deteriorate early.
6) Our flushometers keep running on after the flush. Does this valve address that?
Run-on is usually a clogged refill orifice in the diaphragm. The Ultima uses a DynaClean wiper spring that scrubs that orifice on every flush, which is specifically there to stop valve run-on. It also carries a high back pressure vacuum breaker to help prevent dripping at the tube.
7) Is this a manual or sensor-operated flushometer?
Manual, with a lever handle. If you're standardizing a restroom on touchless operation, you need a sensor model instead. The upside of the manual version is no batteries, no transformer, and no electrical rough-in at the valve.
8) What finish does the American Standard Ultima manual flush valve come in?
Chrome, ordered as part number 6147161.002. It's a single finish offering, which is what most commercial restroom specs call for anyway.
9) Will hard water or chemical treatment corrode this flushometer body?
The body uses a proprietary brass alloy that resists dezincification, the zinc leaching that pits and weakens ordinary brass in aggressive water. Paired with the chloramine-resistant EvoLast diaphragm, it's aimed at buildings on heavily treated municipal water.
