NATURAL GAS PLUMBING
August 01, 2005

Introduction:
I recently inspected an older home (c. 1955), which was structurally in good shape, but there were a lot of "handy-man special" modifications or repairs. Because most of the inspections we perform are on much newer homes, some of the modifications had me scratching my head. After some research in the code books, I was able to provide the Buyers with the necessary information, but what I found was; As a general rule, if a condition doesn't look right - it usually isn't. With that in mind, I'll get your opinion on one of the highlights of the inspection...

Question:
True or False? Plastic pipe can be used for natural gas plumbing supply lines.
Answer:
True - A LOT of you guessed FALSE, but plastic pipes can be used for gas with significant restrictions. Here are the three major restrictions that dictate plastic pipe usage: 1) Pipes can only be used underground, and must be buried 18 inches below the surface. 2) Pipes must be rated for natural gas or propane and be marked as GAS. 3) Pipes must be wrapped with a tracer wire to allow sub-surface detection. So, while plastic can be used for natural gas supply, its use is very restricted.
