Thank you all for the advice, yes I know the $900 was a waste of money
but we did not know what was wrong with the plumbing or what kind of
pipes we had. So trimming not an option, neighbours ahhhh love the tree
and its soooo beautiful, but they do not have the plumbing issues or
the lets clean thousands of leaves and peel of the purple flowers off
the paving. The pipe is ceramic (old) and it runs for about 6 metres on
a guess, but removing all the paving and grass, is painful as its all
clay. Can we dig a trench and the put the plastic pipe within the
ceramic one? But will try the rootox first as well its, cheaper! BUT
THANK YOU ALL, for some well needed advice.
