I had my 8th leak yesterday and was advised by the plumber that my home, which I have lived in since July, 1995, has this Quest piping. He told me that the entire house will need to have new piping, in order to avoid this recurring problem. He also told me that there is a law suit against Quest, but I cannot find any information about who to call or where to write or what to do. If anyone has information, please send me an email. I need help. Thank you.
