The tank slowly drains until it turns on the water intake. I have replaced the flapper and that has caused the toilet to run less but has not completely stopped the problem. The bathroom was installed several years ago but this problem is fairly new, about the last 6 months or so. What could be the cause and how do I stop it? Thanks! TAG

If the plug doesn't go down completely into the drain hole, water may leak from there. Make sure the chain or whatever it is on is long enough to make proper closure, but not too long that it doesn't make proper closure because it floats all around when you lift it. Also, make sure that the plug is the proper size. If it's too big or small, water will leak until suction is lost and the water drains, then your toilet will run and run.
