This 4 1/2 inch vertical metal pipe is sticking up a foot out of my garden. The previous owner of the property didn't know what it was for. It has 2 hose clamps on it and a cap with a square nipple.
The city utilities don't have a record of its existence.
I want to take it out, but I also want to get as much info as I can about it before I accidentally bust a necessary fixture. Also, there is another building with all utilities on the back of my property. House on property was built in 1983, if that helps. All the relevant utility companies have said it is not theirs.
Anybody ever work with something like it?
UPDATE -- Definitely Drain Cleanout. I loosened the hose clamps and the top came right off and I could see "liquid" about 3-1/2 feet down.
