Tapco 1188999 Flush Valve Kohler Cimarron 1.28 Gpf

Product Description

The TAPCO 1188999 is a replacement flush valve designed for use in low-consumption toilet systems operating at 1.28 gallons per flush (GPF). The flush valve controls the release of water from the tank into the bowl during each flush cycle, making it a core component of the toilet's flushing mechanism. This part is installed by licensed plumbers and experienced service technicians performing toilet repairs or tank rebuild work. Its design matches the original specification for the Kohler Cimarron toilet line, allowing for a direct drop-in replacement without modification.

This flush valve is suited for residential toilet repair applications where the original valve has worn, warped, or begun to leak between flushes. The Kohler Cimarron is a widely installed residential toilet, and tank components on these units require periodic replacement due to seal wear and mineral buildup. This valve restores proper flush volume and seating performance in that application.

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Shut off the water supply at the stop valve and fully flush and empty the tank before beginning work. Follow IPC and local plumbing code requirements for fixture repair. Do not overtighten the lock nut securing the valve to the tank, as cracking the tank is a common installation error.
