American Standard Ultima Manual Toilet Flush Valve, Piston-Type, 1.28 gpf/4.8 Lpf - AMS-6047121

The valve flushes at 1.28 gpf / 4.8 Lpf, so it drops consumption well below a legacy 3.5 gpf unit. One caution: the bowl has to be engineered for 1.28 gpf. Putting a 1.28 valve on an old 3.5 gpf bowl often leads to poor carry and callbacks. Confirm the bowl's rated flush volume first, and match the valve to it.

The handle is ADA-compliant and non-hold-open, meaning it shuts off automatically after every flush rather than requiring the user to hold it down. Note that ADA also governs handle mounting height and the wide-side placement of the handle in an accessible stall, which is an install decision, not a valve feature.

That's the specific problem this one targets. The DynaClean integral wiper spring cleans the refill orifice on every flush, which is the orifice that clogs with debris and causes valve run-on. In buildings with hard water or dirty supply lines, that's the usual root cause of a flushometer that won't shut off. The high back pressure vacuum breaker also helps prevent dripping.

No handing to specify. The Ultima manual valve can be installed left- or right-handed, so the same part covers stalls where the supply comes in from either side. Useful if you're standardizing a whole restroom group on one SKU.

This is a piston-type valve. Piston operation gives more consistent flush volume flush after flush, which matters where you need repeatable 1.28 gpf performance. Diaphragm valves are the other common style and the rebuild kits differ, so if your facility already stocks parts for one style, standardizing on that style keeps your MRO inventory simple. Mixing both across a building means carrying two sets of repair kits.

No. There's no external volume adjustment on this valve, so the 1.28 gpf output is fixed. If your maintenance program relies on field-adjusting flush volume, this isn't the valve for it. On the flip side, it also means tenants and staff can't tamper the setting out of spec, which is why a lot of facilities prefer a non-adjustable valve.

Manual, handle-operated. The Ultima line also includes sensor models, but this one flushes by handle only, with no battery, transformer, or sensor to maintain. For retrofit work where there's no power at the stall, the manual valve avoids running wiring or committing to battery replacement cycles.

It's manufacturer part number 6047121.002 in chrome. Chrome is the only finish offered on this model, so anyone matching an existing bank of restroom fixtures is getting a straight visual match to standard commercial chrome flushometers.
