American Standard Pressure Assist 1.1 gpf/4.2 Lpf Left-Hand Trip Lever EverClean Tank - AMS-4142100

Tank only. The 4142100 is a pressure-assist toilet tank with a left-hand trip lever, and it ships with the coupling components needed to mate it to a bowl. The bowl itself is a separate purchase, so you need to confirm the bowl you are pairing it with is a pressure-assist bowl rated for the same 1.1 gpf flush.

Left-hand. The trip lever is mounted on the left side of the tank and is chrome plated. If your existing fixtures all flush from the right, this tank will not match them and the lever position is not field-reversible on a pressure-assist tank, so order the right-hand version instead.

No. Pressure-assist tanks and gravity bowls are not interchangeable. The 4142100 is engineered to feed a pressure-assist bowl, and the bowl's trapway and jet are sized for that flush. Putting this tank on a gravity bowl gives you poor evacuation and possible leakage at the coupling. Replace the fixture as a matched tank-and-bowl pair.

1.1 gallons per flush, 4.2 liters. That is a high-efficiency rate well under the 1.6 gpf federal maximum, and because it is pressure assist rather than gravity, the flush energy comes from line pressure rather than water volume.

Pressure assist is the choice where flush performance and clog resistance matter more than noise. The 4142100 uses building line pressure to force the flush, which gives a stronger bowl evacuation at only 1.1 gpf and holds up in high-traffic restrooms. The trade-off is a noticeably louder flush and a sealed pressure vessel inside the tank instead of a simple flapper. In a hotel guest room or anywhere adjacent to sleeping space, a gravity tank is usually the better fit. This is a commercial-line fixture.

No separate kit is required for the tank-to-bowl connection. Coupling components come with the tank. What is not included is the bowl, the supply line, and the closet bolts and wax or waxless seal for setting the bowl on the flange, so budget those into the job.

EverClean is American Standard's antimicrobial surface treatment fired into the glaze. It inhibits the growth of stain- and odor-causing bacteria, mold and mildew on the treated surface, which reduces how often the tank needs scrubbing in a high-use restroom. It is part of the china itself, not a coating that wears off with cleaning.

White only. The tank is offered in a single finish, ordered as part number 4142100.02, so if you are matching an existing run of bone or biscuit fixtures this is not the tank for that opening.
