I'd say the OP talked too much.
NEVER spell out electrical theory to plumbers, et. al.
=====
Beyond that, where was your contract with the plumber?
Fix it.
It's defective.
We're in a low-trust situation -- even with home owners.
NEVER present ANY conclusions to GCs or other trades.
Instead: you fix everything like it's magic.
If you can't shut up: just say that you've had to ring-out all of the daughter circuits, recheck all bonds and back check the insulation.
Then hand them the bill.
They wouldn't know EM theory if it bit them.
Your story is ALWAYS what you HAD to do to square up the system. Never dwell on this or that defective part/ connection.
======
Example: I was called in to fix a troublesome industrial circuit.
In an unloaded state everything checked out okay.
ONLY when the contactor pulled in did the control circuit, from time to time, fail to hold.
Lousy labeling, wide spread corrosion sent me on many a wild goose chase.
So when I wrote up the tab all that I focused on was just how brutally difficult it was to find the fault -- and that it took all of my trick test equipment to find it. ( in that rat's nest )
We got our money -- and the customer's maintenance man ended up looking pretty good, too. After all, it took an absolute expert half a day to track the beastie down!
Let that be your style.
