American Standard St454ea01 Toilet Tank 1.28 Gpf

Product Description

The AMERICAN STANDARD st454ea#01 is a gravity-fed toilet tank rated at 1.28 gallons per flush (GPF), designed for use with compatible Drake II and Vespin II toilet bowls. The tank features a left-hand chrome trip lever and is built to support hands-free auto flush operation when paired with a compatible WASHLET+ Ready bowl and WASHLET electronic bidet seat. At 30.00 pounds, the tank ships with a tank-to-bowl gasket, tank-to-bowl hardware, and toilet bolt caps. Licensed plumbers and experienced trade installers handle this type of rough-in tank replacement or new fixture installation.

This tank is intended for residential bathroom applications where a low-consumption, 1.28 GPF flush system is required. It meets EPA WaterSense standards as well as California CEC and CALGreen requirements, making it suitable for installations in California and other jurisdictions with strict water-efficiency codes. The tank is designed exclusively for use with the Drake II and Vespin II bowl series. Items not included but required for a complete installation include the toilet bowl, wax ring, toilet mounting bolts, water supply lines, and toilet seat, all of which must be sourced separately.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes. Shut off the water supply and flush the existing toilet to drain the tank before beginning any work. The toilet bowl, wax ring, mounting bolts, supply lines, and seat are not included and must be installed as part of a complete fixture assembly. Do not overtighten tank-to-bowl hardware, as porcelain components can crack under excess torque.
