i really hope someone can help!
There are six houses that have a shared sewage drain. so house A is at the top, their waste goes down the pipe first, then house B's joins the pipe,then house C etc until it all gets to house F which is at the bottom. The pipe then joins the main sewage system.
I live in house E
The problem is that somebody is flushing things down their toilet in either A,B,C or D which is getting as far as the join with the mains sewage and blocking it. Eventually the pipe fills up until we get sewage leaking up out of the man-hole cover in our back garden. House F has built an extension over their man-hole cover and it is sealed and screwed down so this is why we get the problem first.
Every time it happens, it costs approx £120 to get someone to unblock it.
It has just happened for the second time in a year. The first time, we paid for it, sent a very polite letter to the other houses and 2 of them ignored it. I spoke to one couple and it 'wasn't their problem/fault'. The other house is council owned and they're therefore not responsible.
We can't afford to keep doing this so i'd like to know
a) are we legally all responsible for the upkeep of this shared drain?
b) am i right in thinking that if the blockage is after our shared bit ie on the mains sewage pipe that its in fact our local water board's problem?
c) how do i get reimbursed from the neighbours?
thanks for reading, sorry its so long!
