American Standard Madera 15-Inch EverClean Toilet System With Manual Piston Flush Valve, 1.6 gpf/6.0 Lpf - AMS-2855016

No seat is included, and there is no tank. The Madera 2855016 is a floor mount flushometer bowl sold less seat, and it ships as a system with a manual piston-operated flush valve rather than a gravity tank. Budget for an elongated commercial seat separately, and plan for a pressurized supply line since flushometer valves run off line pressure, not a stored tank volume.

Top spud. The Madera 2855016 bowl is drilled for a top spud flushometer, so the valve comes down to the bowl from above at the rear. If the existing bowls in your building are back spud (the valve enters horizontally through the wall behind the bowl), this one will not match that rough-in and you would need a back spud bowl instead.

1.6 gallons per flush (6.0 liters), the standard commercial flush volume. It carries a maximum 1,000 gram MaP score, which is the highest rating in that test and means it clears a heavy waste load in a single flush. That combination is what makes it a common spec for high-traffic restrooms where double-flushing eats any water savings a lower-volume fixture would have given you.

Two things on the Madera system. The valve uses American Standard's DynaClean self-cleaning wiper spring, an integral spring that wipes the refill orifice on every flush so debris does not hold the valve open. The handle is also non-hold-open, so it shuts off automatically even if somebody leans on it. Valve run-on from a clogged bypass orifice is the most common flushometer callback, and that is the failure this design targets.

The Madera 2855016 comes with a manual piston valve, handle operated. Manual is the right call where you want no power or batteries in the stall, simple parts-store repairs, and the lowest number of things that can fail. Go sensor-operated instead where touch-free operation is a requirement, such as healthcare, food service, or high-volume public facilities. Piston valves in particular tend to be preferred where water quality is poor, since there is no thin diaphragm to foul.

Elongated. That is the bowl shape most commercial and institutional specs call for, and it is what plumbing codes generally require in public restrooms. Order an elongated open-front seat to match, since a round-front seat will not cover the bowl.

EverClean is a permanent glaze-level treatment, not a coating that gets scrubbed away. It inhibits the growth of stain and odor causing bacteria, mold, and mildew on the china surface. It is not a substitute for cleaning, but in a restroom being turned over fast by janitorial staff it slows down the staining and odor that otherwise builds up between cleanings.

The bowl has a condensation channel built in, which catches and manages the moisture that forms on cold china in warm, humid rooms. That matters most in unconditioned or high-humidity restrooms where dripping fixtures leave standing water on the floor tile and create a slip complaint. It is not an insulated tank, but on a tankless flushometer bowl the channel is the relevant feature.

It is offered in White, ordered under American Standard part number 2855016.02. The .02 suffix is American Standard's White color code, so if you are standardizing a facility on white china this matches the rest of the Madera line.
