American Standard 4021016 Toilet Tank 1.6 Gpf

Product Description

The AMERICAN STANDARD 4021016 is a close-coupled toilet tank designed for use with the Cadet 3 flushing system, delivering 1.6 gallons per flush (GPF) with a 12-inch rough-in requirement. The tank features a flat lid for added countertop storage space. Internal components include a 3-inch flush valve with a chemically resistant flapper, a Fluidmaster pilot fill valve, and a chrome-plated trip lever. The EverClean antimicrobial surface is permanently applied to inhibit the growth of stain and odor-causing bacteria, mold, and mildew. Installed by licensed plumbers in residential applications.

This tank is engineered for residential bathroom installations requiring a 12-inch rough-in dimension. It uses a Speed Connect tank-to-bowl coupling system for straightforward installation alignment. The bowl is sold separately. The 1.6 GPF flush volume meets current low-consumption plumbing standards. This unit is suited for new construction and retrofit projects where the existing rough-in measurement is 12 inches.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and flush the existing toilet to drain the tank before beginning any tank replacement or new installation work. Use the included Speed Connect coupling hardware and verify a watertight seal between the tank and bowl before restoring water supply.
