If only it were so! Houses in my area have very nice copper plumbing, but
the water pipe connecting the copper to the main in the street is plastic
all the way. The copper never even touches the ground!

NEVER ground to hot water pipes - ALWAYS use the cold water pipe,
as it goes directly to the earth outside the building. The hot water
pipes are routed through the hot water heater(s) and are NOT a direct
path to ground.
