Each year for the past three years, our sewage system on our side of the house gets blocked and we're forced to cough up $500+ to remove tree roots to clear the blockage.
I believe the tree roots are coming from my neighbours side, as we don't have any trees on that side of the house but there is one directly next to where the pipe break is. However, I understand tree roots can come from any where and I have no proof it's the neighbour's tree being a problem.
The last time the pipes got blocked I requested the plumbing company take their sewer camera out to check. They confirmed roots were in our pipes, but they wouldn't/couldn't say it was from my neighbour's tree.
I highly suspect it's my neighbour's tree but I have no proof. I want my neighbour to at least chip in some % to fix the issue so my questions are:
1) What proof do I need to show to demonstrate the neighbour's tree is an issue?
2) What professional do I need or this job?
3) Was the plumbing company taking the p*ss when they said they couldn't show the source of the tree roots?
I think you need new plumbing, even if you remove the tree, there's a crack/break in your pipes that will be exploited by other plants.
