Air pipe under doorway?

[uselessFCUK]

Last year I tiled our newly fitted kitchen, floor and wall, diy style and a good job it was. The kitchen floor leads to the living room's wooden floor which was fitted by a pro. I decided to fit a door tread to tidy the join in the doorway, a post-tiling-thought.

I decided to screw the tread into the base floor. Whilst drilling 1.5" down for the rawls I felt a gush come up from the freshly drilled hole. What a daft place to put a compressed air line. It suddenly dawned that it was the pipe to the gas fire. Oh dear! "Transco please". £85 plumber bill 2 days later.

I have worked on industrial steam pipelines at 100psi, hydraulics systems of 6500psi and refrigeration systems at 400psi but I have to have a license to work on gas lines at 8 psi!

8 psi? 3/8 psi more like (21 mb)
