Then there are cable company guys who run the cable on the opposite side of the house that the power comes in. The electrician for the power grounded it right at the service entry for the power company. The cable guy grounds the cable at the nearest water pipe, example base board heat.

By law, this isn't legal at least that's what I was told in school. Due to the imbalance of the grounding spots. Granted, the hot water pipe is grounded at the same spot as the electrical service. However, how many solder joints has it gone through? 3, 4, 10 or more?
