g'day gas bag,
not sure there is anything that could be pt down the drain that would
be assured of working, one bloke i heard used to tip a bottle of
glypho down but never ever herd if it worked, most poisons need to be
applied to the leaves, ther are tree killer poisons that get applied
into holes bored in the trunk, they may work but might be very
and as has been said the tree may become unstable and fall and do
have you identifyed which tree(s) are doing the harm? the worst
culprits are ficus (anywhere within 40 meters of the drain) mango's,
willows those types but any tree too close could do it?
so it sounds like you have older type pipes caly pipes they are the
easiest joints for roots to get through, if you ahve modern poly pipes
and they are glued corectly then roots almost can't get in, so maybe
you might need to replace those pipes?
or put in a root barrier between the offending trees and the pipes?
or remove the trees ok if they are you trees all you need do is make
the decision if they are neighbour or street trees then that is a
whole 'nother story.
for me as most of the above could be a hassle in various forms i'd cut
to the chase and replace the pipes.
