I purchase home that was builded in 1985 and I didn't know it had poly butyl thoughout the house. I started having problems with the plumbing last year. I had two water leak in my bedroom (same area)and again this week. This time it's from the ceiling (master closet). I'm afraid
this will continue until I have all poly butyl replaced.
If I may I like to add my name to the list of Class Action Suit.
