Why does the label on the Poly Tubing say “Not for potable water” and “For outdoor use only”?
A. Do not use Dial’s poly tubing for potable water. The tubing material has not been approved for potable use. Do not use Dial’s poly tubing for indoor, garage or attic applications. Poly tubing may leak due to wall thickness variations and tubing degradation over time. Only use copper tubing that has been approved for indoor applications and/or potable water.
