A few years ago, I bought a water butt for the back garden. The idea is that I get to keep all of the rain that falls on the back half of my house roof and then use it instead of the liquid gold I’m currently getting charged for by Southern Water.
At the time I realised it would take ages to repay the cost of it, by the time I had bought the barrel, the stand, the piping and the tap; it would be something like 50 barrel-fulls before it would break-even. I was doing my bit for the environment, though; plus it’s something useful to have (at the time there wasn’t an outside tap).
The other night it was raining and I was just locking up downstairs before going to bed. Then I heard the water trickling from the supply pipe into the water butt. It sounded quite loud and that made me realise something: if it’s loud, then the water must be falling a long way from the supply (at the top of the barrel) into the current level. That can’t be right because it’s rained for the past three days and it was full before that.
So at 1am I was outside in the rain with my torch and discovered that there’s now about 3 inches in the bottom of the barrel. Hunting around I found there appears to be a split in the bottom of the water butt and there’s a steady stream trickling out of it. I think the weight of the water must have something to do with the size of the split, because the last time I looked, it wasn’t losing any more.
So that’s a waste of money and the savings have literally gone down the drain.
