Barry,

You got me on that one. I included the bathroom pics because it is also along the rear basement outside wall. The supply and waste piping in this area was affected by the same freezing scenario. The original supply piping to he kitchen addition has been modified from the original outside wall configuration. Are you aware of specific code outside of general construction practice and common sense regarding the distance between supply/waste pipes and the outside wall and also what insulating methods could be taken if this has been compromised?

Thanks,
