There is nothing I can add to this story headlined "Elephant picture explains mystery of leaking jacuzzi" in the Telegraph. All you need is the photo caption:
An elephant nicknamed Troublesome is snapped taking a drink from the pool at Etali Safari Lodge, South Africa. Susan Potgieter, owner of the lodge, said: "When I first saw the photograph of her drinking I couldn't believe it. It was something of a relief because we had been trying to work out why the pool had been draining so quickly for weeks but couldn't find a leak anywhere."
