We all know that this is a touchy subject. That is why I would like to discuss it here. There are a lot of viewpoints on this and I have come across many electricians and inspectors that differ in opinions on this subject.
There is no need to comment that you only see PEX these days, we are talking about copper piping systems, key word systems and the need for the system to be bonded.
My personal thought is that if there is a metal mixing valve installed in the system (crimped/soldered) then there is no need for a bond across the hot and cold. Most, if not all water heaters come with dielectric fittings making bonding across the hot and cold a requirement when the water piping system is broken into two areas, hot and cold.
Will you find a code section that tells you to specifically bond the hot and cold? No there is not. There is a requirement, however to bond the system.
Some don't understand, some do and some just do because it was always done that way. What is your opinion on this subject? Do you require it in your town and why / why not?
