I have a customer that has Twintran installed in 1989, they are trying to sell the house and one of the inspection objections is the twintran tubing. The only stamp I can find is "UPC 2774 see boca research report number 87-51. Anyone have any idea if it is the dreaded Entran II? The install date is right, the color is right, but nowhere can I find a stamp that says Heatway on it, or Entran. Any help would be appreciated.

Thanks in advance!

    Same basic product and it was included in the Goodyear Settlement

    Flush it, and isolate it with a HX is one common fix. If it becomes brittle and cracks, you're done. If it is in a slab it's tough to know if you have bad or brittle sections.
