(I can't seem to locate the threads I saw where I learned about the following - so my apologies if this was covered and I missed it. I'm so happy to have found this forum )
I have several Toto toilets all with the G-max filler - the new one with the white screw that adjusts the water level. They don't make the water level rise to the top of the overflow but they have started to drip continuously through the narrow filler tube that goes down the overflow to fill the bowl.
There was discussion that a cap replacement (using the Korky528 replacement cap) would work to fix the problem, but then I read that they don't work with the "new" ones with the white adjustment screw. Is that the case???
If that's true, then I will follow Lee's advice and get the Korky528T from Ace and replace the whole filler assemblies.
Thanks for any help you can provide
