I have an unusual problem I need some advice on. I am working on a commercial building for a state owned agency using EMT conduit I found a split in a 90 degree bend I made when we first started the job thinking it was an isolated incident I just replace the conduit with a new piece and after running around 1500 feet I found maybe 3 more joints that would tear where the weld was made, now these were all in an office area so I start working in the shop portion of the building and my hands start finding splits in the conduit pieces I have not even touched. So I call the wholesaler who sold me the conduit and after several calls I am in touch with the manufacturer I tell him we have another 700 feet left to run and he tells me there was a factory problem with the conduit and it has been recalled. The walls in the office area of my job have been sheet rocked and finished, this rep for the manufacturer is telling me the conduit run behind the walls will be ok and no problem should come from this later, my opinion is it all needs to be replaced what do you guys think? I have not said anything to the state about what is going on yet without knowing what the final decision will be from the manufacturer of the conduit he is awaiting a sample to see if this is the same problem they had with the recall; any input from you guys would be great sorry for the long post.
