Property management called about a gas leak in the csst piping. there was no bonding and lighting punctuured a hole in the pipe. Now they want it bonded. It is a pool house feeding a boiler for the pool heater. Does my #6 need to go back to the service in the main building or can I take it to the 200amp sub in the basement? I don't know if the sub panel has a ground rod. Thanks.
