Haha! I will suggest that to them.

We did finally nanage to unplug the drain but it was a big job. Apart from the pipe there's an open gutter that it then flowed into that wends its way through the whole Sugar Factory - that was also backing up and had to be dug out - a job that i guess hadn't been done since the Japanese were here.

Looks like it's still hanging around, so we can expect another day of it at least, though from my end, i'm happy. The temp has dropped off a lot and i can take a break from watering things for a while
