I have building steel and under ground water metal pipe as grounding electrodes which have grounding electrode conductors from main service disconnect.

The transformer has from xo grounding electrode conductor to building steel. However their is another conductor from transformer xo going to water piping metal interior piping.

If bonding jumper to water metal piping interior is installed would this be a problem?
