American Standard 4035.216.020 Flowise Dual-flush Tank

Product Description

The AMERICAN STANDARD 4035.216.020 is a replacement toilet tank designed for the FloWise dual-flush toilet system. It features an unlined interior construction and ships in white. This tank is a direct component of the FloWise platform, which uses a dual-flush mechanism to allow selection between a reduced-volume flush and a full-volume flush. The unlined design means the tank interior does not include an insulating foam or plastic liner. Licensed plumbers and experienced installers handle this type of replacement as part of a toilet repair or partial fixture replacement.

This tank is intended for residential plumbing installations where the FloWise dual-flush toilet is already in place. It is a white-finish tank suited for standard bathroom settings. The dual-flush configuration makes it appropriate for installations where water conservation compliance is a consideration. This is a plumbing-category component cataloged under the toilet subcategory and is matched to the FloWise toilet system by catalog number.
