Its not even as if he's had the courtesy to tell us.
His sewer which is on the same run as ours was blocked, our section was fine though. He's built an extension over his manhole so asked DH if it was ok if he popped over to rod from our m/h. DH said yes, we were out the next day. Come home to find our hose pipe has mashed up bits of shitty loo paper all over it.
Going to have to buy a new hose pipe now as there is no way I'm using it again. And next time his sewer blocks up he's going to struggle clearing it as there is no way he's using our manhole.
