I am currently working for a low voltage contractor. There is another electrical contractor on the job who is running our conduit. Due to a problem with the underground PVC conduit they ran, we had the conduit dug up to try to find the problem. The problem we found astounded us. They changed conduit sizes, going from 1" to 1 1/4", by sticking the 1" conduit INSIDE of the 1 1/4" conduit. They have refused to fix this. My question is, what code sections can be quoted that would prohibit this? One would hope that common sense would prevail, but unfortunately, this is not the case. I have looked in the code book, but can't find where it specifically says that you can't change conduit size in the middle of a run. I found a few sections that would apply but they're a bit ambivalent. Thanks for any help.
