Toto "drake" toilets parts ?

[catraveller]

We have 3 of them installed in our house 2 yrs ago. One of toil tank refills to non-stop overflowing after a flush. Where can I buy replacement parts ? ( I assume it is the G-max mechanism.)

Korky makes the fill valve found at many hardware stores.
Quietfill valve
Sometimes replacing or cleaning the assembly cap does it.

Parts can be found at any Lowes, including the red and blue flappers fro TOTO made by Korky.

Thanks for the pointer.
can this
Hunter / Korky Quietfill / TSUO4A.5 / toilet tank fill valve
completely replaced the TOTO part ?
I had expected there are some magic to Toto G-max system.

Will this part still provide the power flush in the Toto Drake toilet ?

The parts interchange.

The filler doesn't make that much difference - it is the design of the waterways when you push the lever to flush that makes the difference, filling the tank back up at the end is sort of anti-climatic. Note, the right flapper valve does matter - get the wrong one and it may not use the right amount of water, defeating some of the water saving design or performance. Course, some brands use different sized holes and other brands/types of fillers won't work on a particular toilet. My unprofessional opinion.

Thanks for the clarification.
I will go get this part and hope to solve the Toto Drake overflow problem.

I bought and installed Korky Quietfill fill valve in the Toto Drake toilet, solved the overfill problem.
This part are so close to the Toto orig that the Toto cap fit over the valve.
