      We have a 1/2″ iron pipe that provides domestic water to a commercial building. Water usage is not substantial, but flow has decreased. It appears to be rust/scale in the pipe (flow is good at the meter). The pipe would be difficult to replace. Is there a tool/snake made that is rotated in the pipe, removing some of the rust/scale? I realize this is a temporary measure, but the building does not require a lot of water volume. Thanks.

      In many cases the rust/scale on the inside of the pipe is sealing rust holes in the pipe and if something could ream them out, you would probably have numerous leaks.

      To rephrase fourth year: replace the service pipe.
