Mr. Israel Wright has brought up some very sound points with regard to piping supports.

If you have excessive runs of unsupported piping this would could cause severe banging in the system.

Have someone run the fixtures in question as another person searches the crawl spaces. OR try closing off one toilet and see if this noise stops then try another toilet. Good luck
