3 Inch Dual Flush Valve Replacement Kit for One-Piece Top Button Toilets — Open-Box, 17% Off

ONLY FOR 3-INCH ONE-PIECE TOP-BUTTON TOILETS – This toilet dual flush valve is designed specifically for one-piece dual flush toilets with a top push button; it does not fit two-piece or side-lever toilets. Fits measured flush valve openings from 3.2" to 3.7" and tank lid button holes from 1.9" to 2.2". The 3-inch designation refers to the valve size category, so please measure the actual tank opening before ordering. Compatible with select models from brands such as Glacier Bay, AquaSource, Project Source, HOROW, DEERVALLEY, TOTO, Kohler, and Water Ridge when dimensions and structure match.

COMPLETE INSIDE-TANK REPAIR SOLUTION – This dual flush toilet kit combines a replacement flush valve, adjustable fill valve, top push button and sealing components in one push button toilet flush kit. It helps address leaks into the bowl, constant running water, ghost flushing, weak or inconsistent flushing and misaligned or unresponsive buttons caused by worn toilet inside parts

NO-CUT ADJUSTABLE DESIGN FOR MORE TANK PROFILES – The fill valve adjusts from 8" to 13", while the telescoping overflow tube extends from 8.3" to 13" / 21–33 cm. Unlike fixed tubes that may require trimming, the no-cut design helps prevent cutting mistakes, simplifies water-level adjustment and makes this complete 3 inch toilet repair kit easier to install

HALF FLUSH & FULL FLUSH WATER CONTROL – Use half flush for liquid waste and full flush for solid waste to reduce unnecessary water use while maintaining practical daily flushing performance. Actual flush volume depends on the toilet design, tank water level and final valve adjustment

DURABLE PARTS & RELIABLE SEALING – Made with corrosion-resistant ABS components, stainless steel parts and extra-thick rubber seals selected for toilet tank use. The durable construction handles repeated water exposure, while the sealing components help reduce leaks and support dependable performance after correct installation

Product Description Repair an older one-piece dual flush toilet without replacing the entire toilet. This toilet push button dual flush valve replacement kit combines the main components needed to replace worn internal tank parts, including the dual flush valve, adjustable fill valve, top push button and sealing components. Before ordering, confirm that your toilet is a one-piece model with a top-mounted dual flush button. This 3 inch toilet repair kit fits measured flush valve openings from 3.2" to 3.7" and tank lid button holes from 1.9" to 2.2". It is not designed for two-piece toilets, side-lever toilets or tanks outside these measurement ranges. The adjustable fill valve extends from 8" to 13", and the telescoping overflow tube adjusts from 8.3" to 13" / 21–33 cm. Because the overflow tube adjusts without cutting, it helps accommodate different tank profiles, reduce trimming errors and support proper water-level setup. When worn dual flush toilet parts cause water to leak into the bowl, continuous running, ghost flushing, weak flushing or button problems, replacing the internal assembly can help restore more reliable daily operation. The half-flush and full-flush controls allow users to select the appropriate flush for liquid or solid waste. The ABS components, stainless steel parts and thick rubber seals are designed for repeated toilet tank use and water exposure. Correct measurement, gasket positioning, installation and final adjustment are necessary for dependable sealing and flushing performance. Compatible with select Glacier Bay, AquaSource, Project Source and Water Ridge one-piece top-button models only when the measured openings, tank profile and internal structure match. Brand name alone does not confirm compatibility.
