1946 house, WA state. This pipe was in the backyard near the corner of the house:
The unusual location and size throw me off. I didn’t measure the diameter, but it’s probably 2 inch OD at the ground.
It doesn’t look like any oil tank fill I’ve seen, and I didn’t find other evidence (pinched-off copper lines, vent pipe) of an oil tank.
Then, this obviously disconnected gas line was on the other side of the house:
So, is it just an older, disconnected gas line or could it be something else?
