Another "What the heck was that for"? question

House built in 1947, public water, public sewer. The large screw valve on the floor does not seem to do anyting except rotate. The picture is dark, but the floor had been dug up around the valve and the cement replaced, si it may not have been orginal. This is in the basement on the front side of the house, just uner the main water shut off valve. So what do you think it is.

Exactly. When the city sewer backs up during a hard rain, you run down & spin the valve shut so sewage doesn't back up through the floor drain.

That's what I thought.

If that's the case, it might be wiser to install a backwater valve there.
