So my water bill skyrocketed last month and finally discovered it has something to do with my autofill. I did replace the float and when the float is pulled all the way up, I can still hear water flowing. So there's a hole next to the float and I noticed water coming out of it (not a full flow, but not a trickle either)..anyway, I put my finger in it and I definitely feel water coming out. Is that normal? My neighbor said it wasn't and I'm not even sure to begin how to even diagnose. Any ideas?
