I have been postponing my much needed repair - Kohler toilet leak. It was not constant leak but like a "ghost leak" I hear the water running especially in my sleep when I was half awake in the early morning. Finally bit the bullet and did some youtube research for "How to fix it - DIY way?"

I didn't see anyone posting it using the universal Korky valve and no close-up look of the tower style toiler flush so here it is - https://www.youtube.com/watch?v=q6E4w860TbI

You can buy parts from here - cheaper universal seal kit (2 in a package) than the Kohler's seal valve part.


The hardest part of the whole thing was to twist 1/4 turn (90 degrees) counter-clockwise the inner shaft to separate the shaft tower from the base.
