    Can you give me more details? Where does the noise come from? The tank? The bowl when it's flushed or the pipes?
    Knocking, popping, creaking and crackling pipes are a common complaint, especially in colder weather. I can tell you what's happening and take the mystery out of it but you're not going to like the repair. When a flush is made drain line expands against a pipe strap next to a stud and when you flush water from your toilet it goes into a chase that is a little cooler then room temperature. The heat expands the pipe causing it to rub against the stud to which it is pipe strapped. This is the sound you hear. As it cools it contracts and the noise is heard again. To repair it you must tear open the walls and locate the pipe strap that's causing the problem and shim it tight. Most people when they learn what causes it just elect to live with it. This is just one possible explanation. Regards, Tom

    Toilet is not in use when you hear tapping. I think its coming from tank. It doesn't do it all the time.

    Remove the lid and check the water level. Is it close to the top of the white overflow tube
