I own a 1984 double wide mobile home, It has the PB pipe in it. This piping has caused damage under the house, as well as in the house.The piping seems to be faulty at the fittings only.I just replaced a section that had appeared to have blown appart at the crimping ring.This scenario has happened 3 times.I am interested in the class action suite,could you send me info? sincerely, Don
