American Standard Afwall Millennium Wall-Hung EverClean Toilet System With Manual Piston Flush Valve, 1.28 gpf/4.8 Lpf - AMS-2856128

The Afwall Millennium system ships as a bowl plus a manual piston-operated flush valve, so you are not sourcing the valve separately. The valve uses a non-hold-open handle that shuts off automatically, and it includes an integral wiper spring that cleans the refill orifice on every flush to help prevent run-on. You still need the carrier, supply stop, and spud/seat hardware to finish the install.

It is a top spud elongated wall-hung flushometer bowl, so the valve connects above the bowl at the rear rather than through the wall behind it. If your existing rough-in was set for a back spud bowl, the supply penetration height will not line up and you would need a back spud model instead.

Yes. A wall-hung flushometer bowl carries no floor support, so it mounts to an in-wall carrier that transfers the load to the floor and provides the waste connection. That carrier is a separate item and has to be set during rough-in, which is why wall-hung fixtures go into new construction or full gut work rather than a straight swap of a floor-mount toilet.

It flushes at 1.28 gpf (4.8 Lpf), which is the high-efficiency rate commonly called for on commercial water conservation specs. Waste removal performance is rated at the maximum 1,000 gram MaP score, so the low volume is not costing you bowl clearance.

That is what the DynaClean self-cleaning wiper spring is for. The integral wiper spring wipes the refill orifice clear on every flush, which is the orifice that fouls with grit and scale and causes valve run-on. It is a mechanical piston valve with a non-hold-open handle, so there is no sensor or battery to maintain.

The Afwall Millennium system here is the manual piston version: a handle-operated valve with no power, no sensor, and no batteries, which keeps the maintenance burden low and the failure modes simple. Sensor valves make more sense where touchless operation is a requirement of the project, like healthcare or high-traffic public restrooms. If the spec does not call for touchless, the manual piston valve is the fewer-parts choice.

Elongated. That matters for stall depth and clearance in front of the fixture, and for ADA-compliant stalls it is the usual specification. Seat ordering follows the bowl, so you need an elongated open-front seat, not a round one.

EverClean is a permanent surface treatment fired into the china that inhibits growth of stain- and odor-causing bacteria, mold, and mildew on the surface. It is not a coating you reapply. For high-traffic restrooms in schools, airports, or stadiums it cuts down how hard the porter has to scrub, but it is not a disinfectant and does not replace cleaning.

White only, ordered as part number 2856128.02. If you are matching existing fixtures in a facility, white is the standard commercial china color and will line up with most restroom rehabs.

Yes, the Afwall Millennium bowl includes a condensation channel. In humid restrooms or buildings with cold supply water, sweating china drips onto the floor below the fixture; the channel captures that runoff instead of letting it track down the wall and pool under a wall-hung bowl where you cannot see it.
