I am in the same place. My boyfriend purchased a mobile home about 4 years ago. I work for a water utiltity and had told him about the recall on Quest. He didn't realize at the time he had this piping. We have had to replace the flooring, the cabinet and tile in the kitchen. We have had the line to the hotwater line to the garden tub break and now the line to the hot water heater is leaking. As you walk through his home you can tell where there is a leak becuase the flooring is sinking in. I would like to know too, what I can do and who I need to contact to get this matter taking care of.
