When things are done quickly to meet a deadline, or simply to get something done quickly, it lacks quality. And often it can lack safety! And its unprofessionalism can stick out like a sore, well, thumb would be too small...
This water heater replaced the one that was still sitting in another part of this basement!
The other heater was much taller than this one is. And you can tell from the wiring, maybe 8" or so.
That blue plastic thing is a connector clamp. It should be secured into a hole on top of the unit into which the wiring is intended to go. The clamp holds that wiring in place.
All those electrical connections should be inside a box provided in the water heater, which comes with its own metal cover, in addition to the cover on the heater.
I'm impressed he used wire nuts! Often those aren't used at all!
Also, do you see the brass pipe sticking out, with the yellow tag hanging from it. That is the Temperature Pressure Reduction valve (called the TPR). It releases any steam from inside should the water get too hot for some reason.
If that discharges its steam onto someone, the temps can be as high as 275F! And quite dangerous.
For that reason, a tube should be connected to the TPR valve which extends to within a 2" or so of the floor. That way, should steam discharge, it does so harmlessly.
My recommendation: it is easy to spot unprofessional work. But if you are going to do something, it is quicker to hire a professional!
