I suspect that one of the bends made is too small in radius to comply with code...and the EMT almost certainly has a "flat spot-" even if this guy stopped just short of a kink.

With workmanship like this, no one should be surprised to see that the EMT is completely unsupported, or to find #12 wires serving a 30 amp water heater (yes, he did that also.) And, of course, no ground wire- even though there is flex used.
