Question Pinhole in pipe

We have a pin hole size leak in the pipe leading from our water meter inside the house to the outside of the house. Water is misting out. Wondering what we're looking to repair...something easy that we can do ourselves or very involved that requires an expert. Any advice would be appreciated

Buck19, Welcome to the DIY Forums.
You didn't say if the pipe is copper, galvanized or plastic. First of all, the water would have to be shut off at the street valve. If the pipe is copper or plastic and you have room to work, you could probably cut it and install a coupling then re-install the meter. If it is galvanized, you will need a lot of tools (cutters, threaders and such and a LOT of room to work. This is assuming you want to do a proper repair and not just a patch job. Patch could be done with a piece of rubber and a small radiator clamp. Good luck and let us know.

If your plumbing is copper and you have a pinhole leak, it could be that your water is acidic. Acid water eats copper pipes over time. If you have one pinhole leak because of acid water, you probably have more on the way. Check the ph of your water and see. If it is acidic, you need an acid neutralizer. If you have old, acid water damaged copper pipes, you have a maintenance issue. Good luck, I hope that isn't the case.
