Well, that black iron street elbow doesn't exactly help matters. My guess is that the other connection behind the roll of toilet paper is done the same way. What a total no-no in the world of plumbing. Black iron fittings are only permitted for gas or steam.
From the angle of the picture, there may be enough slack left so that even if the tank tips over, and twists around, the connection will still remain intact and the overturned mobile home will still have hot water. Of course, this assumes that the edge of the knockout doesn't cut into the conductors' insulation. Obviously, I am joking.
There's no doubt that this installation includes the use of an orange extension cord. At first, I had to zoom the image just to make sure since #10 Romex is orange now. Those flexible connectors for the water connections are also a dead give-away of a "Harry Homeowner" installation.
Please tell me that this is a joke and that you set this picture up to mess with us!
