. . . snip . . . He pointed out (correctly) that just because my main is under his property, it doesn't give him the right to cut it off, but neither does it make it his responsibility. It is really badly rusted up, (I've cut them before - I know what they're like) and if he reconnects it, it could block completely in six months time, by which time all his floors will have been re-laid and I can hardly expect him to dig his floors up for my main. He has offered to connect up temporarily, but I told him to wait for the outcome of the call on Monday and see what happens from there. So it's going to cost me, which I wasn't anticipating, but it'll be an end to it. I'll see how Monday goes. Things are calmer now.
