American Standard Heritage VorMax 1.28 gpf/4.8 Lpf 12-Inch Rough Tank Only - AMS-4270A104

No. The 4270A104 is a tank only, so the bowl and the seat both have to be ordered separately. A chrome-plated trip lever is included with the tank. If you are replacing a cracked tank on an existing VorMax two-piece, this is the right part to order; if you are doing a new install, you need the matching Heritage VorMax bowl as well.

1.28 gallons per flush (4.8 liters), which is the high-efficiency rate rather than the older 1.6 gpf standard. If you are swapping a tank onto a bowl that was engineered around 1.6 gpf, the flush volume will not match what the bowl expects, so keep the tank and bowl in the same VorMax family.

Two colors: White (4270A104.020) and Linen (4270A104.222). Order the bowl in the matching color code, since a white tank on a linen bowl reads as a mismatch across the room.

American Standard classes the Heritage VorMax as a residential fixture. For single-family, multi-family units, and light hospitality guest rooms it is in its intended service. For a high-traffic public restroom, a flushometer bowl with a commercial-duty valve is the better call than a residential tank type.

The Heritage VorMax pairing gives a 16-1/2 inch rim height, which is the taller comfort-height range rather than the roughly 15 inch standard bowl. Rim height is a function of the bowl, not this tank, so order the Heritage VorMax bowl to get that height.

Yes, and that is a reasonable MRO approach here. The tank is a discrete orderable part (4270A104) rather than a one-piece casting, so a cracked tank does not mean scrapping the bowl. Stock one spare in the color you installed, White .020 or Linen .222, and a lid drop or a hairline crack becomes a same-day swap.

2-1/16 inches, fully glazed. The glaze is the part that matters day to day: a glazed trapway wall gives waste less to catch on than a raw china surface, which is what you want in a rental unit where you are not there to plunge it. As with rim height, the trapway is part of the bowl, so this spec applies to the Heritage VorMax bowl the tank mounts to.

Vitreous china, with American Standard's EverClean surface treatment that inhibits growth of bacteria, mold, and mildew. Vitreous china is the standard fixture-grade material, non-porous once fired, so the interior does not absorb mineral staining the way an unglazed surface would.
