Product Description
The AMERICAN STANDARD 4094.015.020 is a replacement toilet tank designed for the Antiquity toilet series. This tank operates at a 1.6 gallons per flush (GPF) flush volume, meeting low-consumption standards for residential bathroom installations. Finished in White, it is a direct tank replacement for plumbers and contractors servicing existing Antiquity toilet installations. Installation is handled by licensed plumbers or experienced trade professionals during toilet repair or retrofit work.
This tank is intended for residential bathroom applications where the original Antiquity toilet tank requires replacement. It pairs with the corresponding Antiquity toilet bowl to restore full toilet function. The White finish matches standard Antiquity bowl and seat finishes. Note that this part has been designated as discontinued by the manufacturer, meaning availability may be limited to existing inventory.

Compatibility
Designed as a replacement tank for AMERICAN STANDARD Antiquity series toilets. Verify bowl model compatibility before ordering. No additional compatible model numbers were specified in the product data.
Installation Notes
Tank replacement should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply valve and fully flush and empty the existing tank before beginning removal. Inspect the fill valve, flapper, and flush handle for wear and replace as needed during the same service call. Do not overtighten tank-to-bowl bolts, as porcelain is susceptible to cracking under excess torque.
