Ok, Let me start out by saying I have not read all the replies and I am traveling so heavy that I only scanned the responses and decided to reply.
Firstly, the bonding jumper around the water meter would be needed IF that GEC [Grounding Electrode Conductor] connection on the line side of the meter (on the side of the qualifying electrode) is also serving as the bonding requirement for a metal waterpiping system within the structure as well.
Since the poster stated that there was a bonding connection downstream of the meter to serve the bonding of metal piping requirements as detailed in the NEC then no bonding jumper around the meter would be required.
Now I will assume you recommended a supplemental electrode on the electrical system to suppliment the water pipe ground as just a good practice even if it was not required at the time of installation(which for all I know could have been in 1920…lol).
The concept of the bonding jumper is to maintain the path around the meter for the GEC is for example installed on the load side (for a lack of a better description) of the water meter which when removed would leave a broken connection between the electrical system and the grounding electrode.
Anyway…I have left out code references on purpose… and hope this helps explain the logic behind the jumper just a little better.
