3" One-Piece Toilet Tank Repair Kit, Adjustable Fill Valve (7.1–12.6 in) + 3-Inch Flapper Flush Valve, Side-Mount Flush Handle & Chain, Fits 3" Opening 3.2–3.6 in, Straight

Rebuild your one-piece toilet tank with a matched set of key components: an adjustable fill valve, a 3-inch flapper flush valve, and a side-mount flush handle with chain. Designed to help address common tank issues such as running water, slow refills, or inconsistent flushing by replacing worn parts together. Fit matters. This kit is intended for one-piece toilets with a 3" flapper-style flush opening (82–92 mm / 3.2–3.6 in) and a side-mount handle hole on the tank wall. It is not compatible with two-piece toilets, push-button/canister flush systems, or front-mount handle holes on the front face of the tank. Handle arm options help you choose the right SKU: Straight arm fits standard layouts, while curved/offset arm can help avoid internal interference and improve chain alignment. For best results, match the shape of your existing handle arm. Installation tip: leave slight slack in the chain (too tight may affect sealing), and set the water level below the top of the overflow tube. Refer to your tank layout and measure before ordering.
