Electrical contractors can be quickly educated to follow an Electrical Code.

The appropriate word is "trained".

Someone who asks a question on PF should surely be helped past that point where misconceptions are generated at every twist and turn by using the water flow analogy.

Using the term "Pressure" for Voltage can be unhelpful. FWIW, the quantity 'emf' is at least called a sort of force per unit charge and not a pressure. This is a perfect example where people bend over backwards to maintain the equivalence between two totally different sides of an analogy. Use the water analogy very briefly and very early on in EM education and then throw it away.
