What would stop the signal from getting to the distribution transformer through the wires? This is why things like power factor and harmonic distortion are regulated (specifics depend on country and customer type). You can mess up the power for everyone else. Or share a network.

The answer is obviously nothing stops it from going to the transformer. You seem to have completely missed my point so let me restate it.
It is odd how in this case the system works across a transformer and into another home yet i found it had difficulties on the two phases of my own home?
It would be interesting to hear for an actual electrician on how this would be possible, and why it didn't work properly for me?
Signal is usually lost going across a tranformer, from one winding to anotner. But usually whole residential areas, consisting of many streets, share a 24kV to low voltage 220V transformer. Meaning you and your neighbour in most cases share a single transformer, to which you are connected to in parallel.
Different phases are never interconnected, have separate windings on a transformer and are on different cables, since there's a voltage between different phases, as they represent three different points on a generator axis and are offset by pi2/3.
