Yes... but that's not to make the pipes a better grounding electrode, 
it's to prevent current from flowing through the meter and damaging it 
from galvanic action.



The plumbing is also connected to

Actually, not brazed, but more likely "exothermically welded"  a process 
using a thermite mixture of copper oxide and aluminum powder. Basically 
welds copper to copper with copper. (Brazing is using a different filler 
metal). A commercial product is "CadWeld"... you get a little ceramic 
mold that fits around the rod and wire(s), fill with the powder, light 
it and stand back.



 My plumbing is all copper including the line in from the
