Need plumbing help

Thats probably service line. Ours comes in thru basement floor(thats normal)
What you can do (and it's probably free) is call municipalities Water Distribution dept and tell them you suspect a leak.
Could get a free repair out of it??
It's a 3/4 pipe on municipal.

I did a water leak test overnight. Took a picture of the water meter, didn't use the water overnight for 8 hours and checked it in the morning and the meter hadn't moved at all.

I think what I have going on is cracks in the concrete slab that are seeping moisture into the house. Found a company online that deals with this sort of thing but who knows what it's going to cost. Going to give them a call today and find out.
