Just wondering whether anyone ever cleans out their water butt? I have never cleaned ours in the nearly 10 years we've had it and since I heard a news report of a gardener dying from Legionnaire's Disease while using a hose pipe, I was worried that spraying it on plants would be dangerous. I noticed you can never get all the water out of the bottom of it either and when the water is left standing there is a greater risk, isn't there?
Thanks
