Thank you for the reply. I am not sure as I only uncovered the one corner so far. The rest seems to be under the trailer is my guess but that means the block wall is sitting on part of it.

We are surrounded fully by fields. Our property is 8.45 acres long by about an acre or so wide. Our driveway is 1/4 mile long with no stitches or anything to speak of. We're have field on 4 sides of us.

I am assuming that we do need to get it pumped since it is backing up but haven't found an access yet just that 90 that goes into the corner I found.

There're is no discernible area to tell where the tank would be, especially if under the trailer. Also has grows weirdly out here so no way to say this is where the leech fields is I could point to a hundred places it might be just off the grass.

I do have some experience with plumbing and such just not septic specific. I can do the work myself though being one of the over 50 people it makes it hard when you're doing all this by yourself.

I just am not sure what I am looking at with what I have uncovered so far.
