Jose G: I started noticing leakage at the rear of my toilet after putting in a tank cleaner with blue coloring. Figured this was the issue so I ordered it and swapped it out. Problem solved!

SUSAN M.: I called Kohler and they gave me the part number, Amazon was cheaper than Home Depot. It took us a while to get it right, we are old. But we did it, it flushes and no leaks.

Bob Travis: Pretty simple job, but can be messy from water and old deteriorated rubber gasket

This kit is an improvement from prior versions
The three screws now have molded plastic heads, which improve sealing, and prevent the screws from rotating when tightening the nuts - making the job easier

NOTE: It really does make sense to replace the toilet fill valve and flapper at the same your doing this

The secret to the job is 1) shut the water supply off; 2) with tank top removed, flush the toilet and hold the flapper up until all the water what will drain out has; 3) either vacuum the remaining water out with a shop-vac (make sure it's empty and clean), or sop up water with some old towels (my preferred method); 4) Unscrew the supply hose; 5) Remove the three nuts/washers and the CAREFULLY tap down then unthread the existing screws; 6) If necessary CAREFULLY tap out the three rubber gasket lugs if they are stuck in the holes in the toilet base [I got carried away once and broke the back part of the toilet base off]

The rest is simple, follow the included pictures

Gil in Toronto: Genuine from Kohler, fit perfectly. Removed one star when the delivery changed from one week before purchase to three weeks after the order was submitted - that caused me some inconvenience as my use was time-sensitive.
