Two pipes in yard

Just purchased a home built in 1930 and noticed two pipes in the yard. Previous owner did not know what they were for either. We are concerned they are for an old underground oil tank. There are also two pipes coming in through the foundation in the basement that corresponds to the same corner of the yard where the two pipes are. The pipes in the yard are about 50 feet from the house. Does anybody know what these might be for? Thanks in advance for help on this.

Underground Oil Tank…
Picture 2 confirms it…

Where are you located?
some states previously permitted abandonment on-site…
Check with your local municipal authority…

Hey Joseph how did you know it was underground and not indoor. What about picture two confirms it?

Servicing the Main Line, PA where a Newer Home means it is less than 70 years old…
you see enough of this type piping to suggest buried oil tank.

So just experience? No text book answer?

If active, there would be a fill cap on the larger pipe and a vent whistle on the smaller one.

Piping configuration generally dsiplay 2 lines of that size. In some cases, an additional line for an interior gage would be mounted and installed where the tee is placed.
I am not sure that there was an installation standard back then that could be cited… :slight_smile:

2 Lines inside , if the tank was inside it not be likely to have 2 going back to the outside
