Today I had the pleasure(?) of sitting through a three hour meeting with the big wigs of the home builders association and several other sub-contractors reviewing a list of codes that will be enforced in my local jurisdiction.
The problem is we have three county inspectors and all of them have different opinions on grounding, bonding, smoke detectors and so forth. Structural issues are also hit or miss when it comes to notching and boring.
Well I'm going through the list and 95% of the codes agree with the NEC but a new bonding requirement made no sense to me.
The new bonding rule will be to bond the "hot" and cold copper water pipes to the service at the water heater. Now this is new to me and I would like some opinions on this issue.
We bond cold water lines but never the hot. I was under the impression that dielectric unions were used on water heaters to keep the lines from pitting. Any info would be greatly appreciated!
