IAN McKELVIE: I want to take us back in history a bit, because I've had quite a bit of experience with water in my time, and I want to go back to when I was fairly small. I remember going with my father to fix the old MacEwans H2 water pump, and in those days you had a cylinder and a water pump—for those who don't know—and they had bucket washers in them. It took a fair while to bend those bucket washers round and get them back in the hole to make the water—and they had to be watertight, you see, so it took a while to get that sorted. So that was my first experience of water. The second one was when I had to do it myself, but luckily things have improved significantly since then. We now have Grundfos water pumps with all sorts of stages in them, and they work really well.
