I am fixing a small leak from the tank into the bowl.
I bought the Korky complete toilet repair kit and am following the installation instructions in their 5 minute video (https://www.korky.com/4010MP)
After I removed the toilet tank, I am surprised to see a rubber thingy on the toilet bowl:
There is just one, on the left side.
The toilet manufacturer's installation instructions don't say anything about a rubber thingy.
And it looks like there ought to be two of them, one on each side? It just seems odd to me that there is just one.
What's going on here? I'm a bit puzzled.
Should I just pretend I didn't see it, replace the tank innards and put the tank back on the bowl like it was, or is this something I should address? (Like put a 2nd rubber thingy in there?)
