:confused: I am in the process of having my galvanized water lines changed to copper in my basement. Job was to be done in one day but took longer than expected and plumber is due back today. I have however noticed that since some work has been done that there is a persistent steady fairly rapid ticking or it can be described as a light thumping sound when water is flowing now. This happens when I run water in the kitchen or flush the toilet. It stops when the water stops running or the toilet finishes filling. I have gone down to the basement and can hear the noise down there to by the new piping. I spoke to the plumber and he said it probably is the meter. However before any work was done no such ticking was ever heard during water running. It this just a big coincendence (as he saids) that my meter is now giving me trouble or is it something to do with installation,- could it be air in the new pipes. I wonder only because I would like to remedy the problem while the work is being done. He wants me to allow them to finish the job before we look at that problem. I am concerned. Can anyone advise? Thanks Anne
PS fyi The house has rad heating but none of the piping for the rads is being changed. The water lines in the upper part of the house were changed during renos about 3 yrs ago without any issues This is the remaining piping in the basement.

Your plumber is likely correct and I'd let him finish the job before tackling the noise. Your old galvanized pipes were probably loaded with build up and that's what lead you to repiping. The galvanized pipe and build up was much more heavy and dense than the new copper. It is like switching from a cast iron drain to PVC, you will hear a lot of things you never heard before.
