This may seem silly/stupid but I have tried to fix this issue myself and it just wont work. One of the toilets in our home just seems to constantly add water. I have tried several times to replace the rubber flap that covers the hole and water just seems to leak out ever so slowly. Like every hour or so water runs and fills up the tank and stops then an hour later it does it again, all day and night.

I have read tips about using Vaseline jelly and put it on the seal ring where the hole is. I did this I scraped the area as well and still it wont stop.

So before I call a plumber or change out the tank does anyone here at TOV have any other thoughts or ideas? Or a good plumber to destroy this piece of junk and add a better tank?
