I'm quite impressed with this chain of thought, brilliant!

How about this theory? Your TC is radiating some EMI that is causing some
appliance or sprinkler system with solenoid valves to spasm? Do you have a
sprinkler system or dishwasher that someone can monitor while you run your
coil?

Sounds like the pipes are reacting to one another, rather than en-masse to
the surrounding ground, much like Ed says.
Out of curiosity I would run it with solely a single earth, and then try
two
pipes alongside one another, as I wonder if pipes of dissimilar metal would
behave differently to two of the same metal?

Yes.
When I have it tuned for top running (still working on primary coil
resonance) with what I had, it did it every time.
At first I thought it was the motor in either the washer or dryer, but then
I grabbed the faucets for the washer and they were shaking to beat the
band.
All I can figure is that the emf from the primary is somehow causing them
to
resonate.
