Got a problem with a shared drain. One of the inspection covers sits either side of the boundary and while it was acessible previously because there was just flower beds between the houses, the neighbour has now removed the cover, shoved some slabs over to cover it up and is building a brick wall over it to border his side off.
I've tried reasoning with the neighbour but he just doesn't care. What can I do to stop him doing this? Council seem like a waste of time. Anyone been in a similar situation?
