in THE MAIN WALL
Just wanted to know if any of you guys in Mass would have the answer to these questions.

What is the smallest gas pipe that can be burried in the ground?

What is the smallest pipe diameter that can be concealed in or behined a wall?

I can't seem to find any of these answers in the Code book so I thought I would ask.

    According to my copy of 248 CMR (dated 3/11/05)

    Mike, see 248 CMR 5.04 (Mass. modifications to NFPA-54) sub-paragraphs (1) and (2).

    Minimum underground line shall be not less than 3/4" and minimum concealed pipe shall be not less than 1/2".
    "If you do not know the answer, say, "I do not know the answer", and you will be correct!"
