Pressure-Assist 1.6 GPF Toilet Tank Replacement System with Handle Kit for Two-Piece Toilets, M-101526-F3BK, 501B Series

This 1.6‑gallon pressure‑assist tank system is engineered for reliable performance in two‑piece pressure‑assist toilets, offering powerful flushing action and consistent flow. It is designed specifically for systems originally equipped with Flushmate III 503‑series technology, ensuring compatibility and dependable operation. Built to fit a wide range of OEM two‑piece pressure‑assist toilet tanks, this replacement system delivers strong drain carry and reduces the need for repeat flushing.

It uses pressure rather than gravity, producing a vigorous flush that meets performance expectations in both residential and commercial environments. The system includes key components such as the vessel (1.6 GPF), tank nut, and essential gaskets for tank‑to‑bowl integration—providing a complete solution for maintenance or replacement needs. Flushmate systems push waste up to 33% farther than ANSI minimum standards, providing superior drain carry for high‑use environments such as hotels, commercial buildings, multifamily housing, schools, and residential settings.
