In a two family unit, the owner is changing all of the gas appliances to electric , so we are upgrading the services to handle the demand(each unit has its own service).The house has one water service from the street,once it comes through the basement wall it's T'd off and goes to two seperate water meters.My questions are, do I bond both services to this one underground water pipe? And do I jumper around both water meters to bond each units metal water piping systems to this same underground water pipe?Thanks in advance for any help.
