No, your fill tube where the flapper sits is probably worn, they sell a kit to fix this or just replace the fill tube completely. Requirers removing tank. I would try kit to fix where flapper sits, it is an epoxy ring that seats itself over exsisting area.

As most city water suppies high mineral and calcium concentration, often using an SOS or Brillow pad to clean mineral deposits from the 'neck' that the flapper seats on to. This improve contact having a clean mating surface. Doing this along with a new flapper should do the trick. I also would coat both surfaces with Magic Lube (Gasket Lube) found at pool supply stores to further seal the 2 surfaces and prevent further mineral build-up. This shoud do the trick 99% of the time.

I had an issue today where the flapper still wasn't sealing. I found the gasket at the low edge of the flapper seat was rippled, probably from a heavy dose of bleach, and the rippled gasket was keeping the flapper from making a good seal on the flapper seat. I trimmed the gasket with a razor knife, and this remedied the problem. --W/D-- I had an issue today where the flapper still wasn't sealing.
