American Standard 3378128ST.020 Elongated Toilet 1.28 Gpf

Product Description

The AMERICAN STANDARD BRANDS 3378128ST.020 is a complete two-piece elongated toilet designed for high-efficiency water consumption in residential and light commercial plumbing installations. Rated at 1.28 gallons per flush (GPF), this unit meets WaterSense certification standards for ultra-low consumption without sacrificing flush performance. The kit ships as a matched toilet-to-go package, including the bowl, tank, wax ring, and plastic seat, reducing the number of separate components a plumber needs to source. The elongated front bowl features a 16.5-inch rim height, a 3-inch flush valve, and a 2.125-inch trapway. ADA compliance is built in at the bowl height level.

This toilet is suited for new construction and retrofit plumbing projects requiring a 12-inch rough-in. The elongated bowl configuration is standard in residential bathrooms and is also appropriate for ADA-accessible commercial restrooms. The chrome-plated trip lever, EverClean surface treatment, and PowerWash rim are factory-installed features. Licensed plumbers install this unit as part of rough-in finishing work on ground-floor or upper-floor applications where a standard 12-inch rough-in drain is present.

Designed for standard 12-inch rough-in drain configurations in residential and light commercial plumbing systems. Confirm rough-in dimension and floor flange condition before installation.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and remove all water from the existing drain line before setting the new bowl. The included wax ring provides a single-use seal between the bowl horn and floor flange — never reuse a compressed wax ring. Torque closet bolts evenly and do not overtighten, as porcelain flanges crack under excessive force.
