American Standard Yorkville Two-Piece Pressure Assist 1.1 gpf/4.2 Lpf Back Outlet Elongated EverClean Toilet - AMS-2876100

Back outlet. The Yorkville bowl sits on the floor but the waste exits horizontally out the rear of the bowl, so it needs a wall carrier or a wall drain stub behind the fixture, not a floor flange. If your rough-in is a floor drain, this is the wrong bowl and you want a standard floor-outlet elongated model instead. Plumbers ordering this for a retrofit should confirm the existing waste is in the wall before it ships.

No seat. The Yorkville ships as bowl and tank only, so add an elongated seat to the order. What is in the box besides the china is the chrome-plated metal trip lever and four color-matched bolt caps. For a commercial or multi-family job, spec the seat to the traffic (open-front elongated commercial seats are the usual pick) and remember to count one per fixture.

The Yorkville is a standard-height bowl, 15 inches to the rim. Accessible-height fixtures land in the 17 to 19 inch seat range, so this one does not get you there on its own. If a restroom stall has to meet accessible seat height, pick a comfort or right-height bowl instead of adding spacers under this one.

Pressure assist uses the incoming water pressure to force the flush rather than relying on head of water in the tank, and the Yorkville pairs that with siphon jet action. In practice that means a harder, faster evacuation of the bowl, which is why these get spec'd in high-traffic and high-abuse restrooms where gravity bowls get called back for double flushing. The trade-off is noise and a pressure requirement: pressure-assist cartridges need adequate static pressure at the fixture, and they are louder than gravity. In a quiet setting, a hotel guest room or an executive washroom, a gravity elongated bowl is the friendlier choice.

2-1/8 inches (54 mm), fully glazed end to end. That glazing is the part that matters on a maintenance call sheet: a glazed trapway gives waste nothing to catch on, which is where clog complaints usually start. Combined with the pressure-assist flush, it is the reason this bowl shows up in schools, stadiums and other buildings where a plunger call costs more than the fixture.

White only, and the part number is 2876100.02. The four bolt caps in the box are color matched to the white china. If you are standardizing a building on white commercial fixtures, this one drops into that palette without a separate trim decision.

EverClean is an antimicrobial finish fired into the china surface that inhibits the growth of the bacteria, mold and mildew that cause stains and odors. It works on the surface, so it cuts down how fast a bowl discolors between cleanings. It is not a substitute for cleaning and it does not sanitize the water, so housekeeping schedules stay the same. For a property manager running a lot of doors and fixtures, the value is fewer permanent stain complaints on bowls that get cleaned on a rotation rather than daily.

There is a condensation channel built into the tank, which catches and redirects the moisture that forms on cold china instead of letting it run onto the floor. That is the feature you want in unconditioned or humid spaces where sweating tanks cause slip complaints and rotted flooring around the base. It manages condensation rather than preventing it, so in a genuinely wet mechanical space you would still watch the floor finish.

10 by 12 inches of water surface in an elongated bowl. A large water area keeps more of the china wet, which means less of the bowl gets soiled in the first place and less scrubbing per cleaning cycle. Paired with the elongated shape, it is a more comfortable fixture for adult use than a round front, which is why elongated is the default in commercial and multi-family specs.

Chrome-plated metal. On fixtures in public restrooms the trip lever is the first thing to break, and a plated metal lever holds up to abuse that snaps a plastic one. It is also the part a maintenance tech can replace without pulling the tank, so keeping a spare on the shelf is cheap insurance in a building with a lot of these installed.
