Oatey K835-76 Universal Flush Valve Assembly 3 Inch

Product Description

The OATEY K835-76 is a universal flush valve assembly designed for 3-inch toilet tanks. It includes two adapters to accommodate both common 3-inch toilet tower sizes: 3-1/2 inches and 3-1/8 inches. The assembly features an adjustable flapper overflow tube, allowing the installer to fine-tune flush performance without swapping additional parts. A tank-to-bowl gasket and all necessary hardware are included, making this a complete repair kit. Constructed of plastic, the K835-76 is suited for residential toilet tank service and is installed by licensed plumbers or qualified DIYers familiar with toilet tank components.

This flush valve assembly is intended for use in standard 3-inch toilet tank configurations found in residential bathrooms. The dual-adapter design eliminates the guesswork of sizing by covering both tower diameters common to 3-inch flush valve applications. All hardware and the tank-to-bowl gasket ship in the box, reducing the need for separate parts sourcing on the service call.

Installation Notes

Installation is performed by a licensed plumber or experienced DIYer. Before beginning, shut off the water supply at the angle stop valve and flush the tank to drain residual water. Disconnect the supply line and remove the existing flush valve before fitting the K835-76. Follow local IPC code requirements for toilet tank service and ensure the tank-to-bowl gasket is seated properly before tightening hardware to prevent leaks.
