A local TV station wanted to do an article on this stuff. I told him all about it, he investigated it, never heard back. A few days later, I called him, and he said that his producer did not want to do the article, because it was so prevalent here in KC that he did not want to alarm the public. See it about once a week. Now that the lines have been in use awhile, issues are becoming more common. If you see it, recommend re-pipe, let the buyer decide. Print off several copies of the InterNACHI article to hand out. Email me, and I can send you PDF copies of what I hand out when I see it.
