Ibc is basically full. Also with the last week of weather, it's basically frozen. But I knew it wouldn't be solid all through, just an inch or so round the edge. Now the situation was thus: I had 7 or 8 25 ltr drums full, enough for today and maybe tomorrow, but wanted to avoid filling them up straight from ro unit, and, while it's milder now it would still take ages for the ibc to thaw enough. So before I went to work I filled a hot water bottle and crammed it in at the tap, and lo and behold, when I came back a few hours later I could fill up from there! I've never read this tip anywhere before, so am claiming it as mine!
