Any thoughts on bonding hot tub to metal gas pipe?
I don’t know if the gas line is grounded to service connection, but it could be easliy bonded to copper water lines which should be grounded.
I don’t believe any broken (ground connections)exist in the water lines. (all copper) Also, my water heater is gas, so the copper water lines and metal gas lines come together at the water heater unless there’s something inside the water heater that breaks the connection.
Thanks,
Jeff
