The latest change, as you'll recall, was using fishing line to connect to the handle rod. Worked ok, but I could hear it occasionally running earlier today. Now it seems like the flapper doesn't reseat the same way each time. It will go for a day, or several days, and then it starts leaking because when it closes it's not reseating the same way. I know this because when I moved it slightly today, the trickle leaks stopped.
Problem is that this is the brass flush valve and I had to get a flapper with a rubber ring that slid down around the overflow tube as opposed to hooking it like the plastic ones. I don't know if having totally soft rubber around this area is the cause of the latest woes... but I'll bet it is. So..... is there a replacement flapper that is either solid in the attachment area or is there one that has a metal or hard plastic ring that would slide down the overflow tube?
I'm at my wits end with this thing, never had a problem this difficult to solve.
BTW, this is an older 5 gallon toilet..
