Main Shutoff Valve Issue

I noticed a drop of water at the main shut-off valve off on the house side of the water meter, There was also some green residue on the beam underneath the valve and when I ran my finger along the underneath of the valve, there was green residue there as well so clearly, there is a slight drip. Its not a lot, but enough to show that there is a drip. (Picture attached)

Not sure if this is related, but the reason I went into the utiliy room in the first place was because I was hearing some water hammer noises as my dishwasher was going through its cycle.

I guess my question is am I due for a visit from my friendly neighborhood plumber to solve this or is this something I can easily solve on my own(and how?)

Many thanks for the advice...

You can fix it yourself provided:
1. There is another shutoff valve on the wall side of the meter (may be outside for example under a cover plate in the sidewalk),
2. You don't break any tamper detecting wires or strips or seals.

There are hex shaped rings at the meter so you can disconnect the pipes from the meter quickly without having to disassemble anything else.

Drain both hot and cold water from the entire system (excluding the water heater) using faucets upstairs and/or a basement laundry tub so only a small amount drains out at the work site as you unscrew the meter connection.

Add or replace some teflon tape if it is the screw joint that is leaking,


The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
