American Standard 6147121.002 – 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 centerline of the spud connection. That's the standard water closet rough-in, so it drops onto most existing commercial toilet supply stops without moving the pipe.
2) Is this flush valve a 1.6 gpf or a 1.28 gpf?
1.28 gpf / 4.8 Lpf. That matters: pairing a 1.28 gallon valve with a bowl engineered for 1.6 gallons can leave you with carry problems, so confirm the bowl is rated for 1.28 before you swap. If the fixture is a 1.6 gpf bowl, order the 1.6 version instead.
3) Is this flushometer ADA compliant for a public restroom?
The handle is an ADA-compliant non-hold-open type that shuts off automatically after every flush, so the user doesn't have to hold it down. Mounting side is your call, which helps when the accessible stall needs the handle on the open side of the fixture.
4) Our flushometers keep running on after the flush. Will this one fix that?
Run-on is usually a fouled refill orifice in the diaphragm. This valve uses American Standard's DynaClean integral wiper spring, which scrubs the refill orifice on every flush specifically to prevent that failure. It also carries a high back pressure vacuum breaker to help prevent dripping at the breaker.
5) Does the handle have to be on a particular side of the toilet?
No. The Ultima manual valve can be installed left- or right-handed, so a stall where the wall or partition blocks the standard side isn't a problem. Same part number either way.
6) Will this hold up on heavily chlorinated municipal water?
The diaphragm is EvoLast material, made to resist chlorine and chloramine so it doesn't harden and fail early, and the valve body is a proprietary brass alloy that resists dezincification. Those are the two parts that typically go first on a flushometer in aggressive water, so it's a reasonable standardization choice across a building on chloraminated supply.
7) Diaphragm or piston flushometer, which should I be buying for a school restroom?
This one is a diaphragm-type valve. Diaphragm units are the common choice in high-traffic commercial restrooms and rebuild kits are widely stocked; piston valves are generally chosen where water quality is poor and debris tolerance matters more. If your maintenance staff already services diaphragm flushometers, staying with a diaphragm valve keeps one rebuild kit on the shelf.
8) What finish does the American Standard 6147121 come in?
Chrome, part number 6147121.002. That's the only finish offered on this manual Ultima valve, which is what you want if you're matching existing exposed flushometers in a commercial restroom.
