I just posted -- and was sitting here reading other post -- and the darn commode started running water again. Just for a few seconds. Should I turn it off? And then turn it on when I need it -- hate to run up a water bill.
Thank you all for your help and suggestions. I tried them ... I went back in my files and found that I had bought that commode in Sept. 09. In Oct. 2013 the plumber came out and installed an identical commode in my other bath and at that time he told me to go ahead and order that part while they were free. He did make some adjustment then, too. Not the part I put in today...
Today, I made note of the water level and found two...the commode is white but the inside of the tank is more light beige. There was a water line and everything below it was dark beige colored. Above it was another water line, about 1/2 " above the dark beige one. I am pretty sure that the difference is when the plumber changed out something back in 2013. Anyway, today when I started watching -- I flushed the commode and waited until it finished filling up. Then I turned off the water where it comes in...and made note, the water was up to the top line. I waited an hour and went in - it had fallen to the first waterline (the dark one). I flushed the water out and took a paper towel and cleaned the bottom (where the new part meets it) and felt around for rough patches. Found nothing unusual. The only thing that came off was the black smudges from the black plastic that is around the edge. Then I filled the tank back up and waited another hour. I checked back and it had again fallen from the top waterline to the bottom (darker) line. I think those waterlines became established after I had the commode installed in 2009 and then changed to higher when the plumber worked on it in 2013. Anyway, after I cleaned it - the water did go down that 1/2 inch but it did not come on to fill the tank again. It has stayed right there at the original waterline.

The brown discolouration is mold growing in the tank water. You can remove most of it with bleach if you want to.
What apparantly WAS happening was that the water would fill up to the upper line and then leak out to the lower line before the fill valve would fill it up to the upper line again, and this would happen repeatedly.
Take a flashlight and look for any cracks in the overflow spout in the middle of the tank. If something happens so that your water fill valve doesn't STOP filling the tank, the excess water should drain down that overflow spout so that you don't get a flood with water all over your floor.
Maybe add water to the tank from a glass or bowl or something, and see if water leaks down that overflow spout when you fill the tank up to the upper line. Use a flash light if you have one. A crack in that overflow spout would explain the continuous refilling of the tank.
Tell us if you see any water leakage down the overflow spout.
If the leakage stops at that lower line, and the toilet still flushes fine when the water level is at the lower line, then the easiest fix would be to just adjust the water fill valve to only fill the toilet tank to that lower line. That doesn't solve the problem of WHERE the leak is, but it does get rid of the water leakage and the toilet continually refilling to compensate for that leakage.
