I informed them when I was there ,they said there were works on the drainage going on . As i said on the blog /app found there is a tap at the back of the vets (courtesy of a local) .The problem you get when no water is some will empty cassette and leave it without flushing . We didn't need to empty as had just come from Ally's but someone had and not flushed it . I managed to get some water from a barrel at the side of the mill that was collecting water from the gutter ,so left it clean .This was when we arrived early afternoon. Got to know about the tap in the morning just before we left so we did top up with water.
