High Water Bill?

Water Bill... Read text first, then see attached video

Jennifer and Jim kept getting huge water bills. They knew
beyond a doubt that the bills weren't representative of their actual
usage, and no matter how they tried to conserve, the high bills
continued. Although they could see nothing wrong, they had everything
checked for leaks or problems: first the water meter, then outdoor
pipes, indoor pipes, underground pipes, faucets, toilets, washer, ice
maker, etc. -- all to no avail. One day Jim was sick and stayed home in
bed, but kept hearing water running downstairs. He finally tore
himself from his sick bed to investigate, and stumbled onto the cause
of such high water bills. Apparently this had been happening all day
long when they were not at home. Knowing that few would believe him, he
taped a segment of the 'problem' for posterity -- see attached video .
