Hi All, thanks heaps for the helpful feedback. Much appreciated.
Not sure of my plan of attack at this stage. Had spoken to the neighbour (husband) a month ago before airing my problem here. He mentioned he will rip out at the first sign rouble, but that might mean at my expense of a plumber first ??
Anyway, I'm not in the good books with the wife who had words with me pulling away some vine from my back brick wall of my garage where their climbing vine had invaded.
Another words not having fun managing neighbourly relations over past 12months.
