We moved in to our house a couple years ago and were not told too much about a pipe that sticks out of our backyard.
We are on a septic system and this pipe is sticking out from our leech field. The other houses on our block all have similar setups yet none (that I know) have a pipe coming up like ours.
It was suggested to me that this may be safe to remove, or at least remove, cover the whole for a few weeks, and as long as there's no issues, then remove.
It's not attached to anything and I can pretty easily pull it out and put it back in, although I've tended not to touch it much.

Can anyone provide any insight here please?
I think it's supposed to be a vent for the leech field. See https://septicpatrol.com/does-a-leach-field-need-to-be-vented/
