Kohler 53346 Brass Rialto Ballcock Fill Valve

Product Description

The KOHLER 53346 is a brass Rialto ballcock designed for toilet tank fill valve applications. Built from brass construction, this ballcock controls the refill cycle of the toilet tank after each flush, shutting off water flow when the tank reaches the correct level. It is a traditional float-style ballcock, a well-understood component that licensed plumbers and experienced DIYers service on a routine basis. At 2.216 pounds, the unit ships as a single assembly ready for installation into standard toilet tanks.

The KOHLER 53346 Rialto ballcock is suited for residential toilet tank installations where a brass float-style fill valve is specified or preferred. Brass construction makes it a common choice in applications where durability and corrosion resistance are priorities compared to plastic alternatives. It fits within the standard toilet tank ballcock service workflow and is appropriate for replacement service calls or new toilet installations requiring a separate fill valve component.

Key Features

• Brass construction for corrosion resistance and long service life
• Traditional float-style ballcock design for reliable tank refill control
• Controls water shutoff based on float level for accurate tank fill

Compatibility

Installation Notes

Installation is performed by a licensed plumber or qualified DIYer. Shut off the water supply valve at the wall before removing the existing ballcock and drain the tank completely. Follow applicable local plumbing codes, which may reference IPC standards for toilet fixture components. Do not overtighten the tank nut securing the ballcock shank, as this can crack the tank.
