If your water bill suddenly doubles or triples, you might assume the utility company made a mistake. There could be a much simpler explanation, and it could be costing you hundreds of dollars.

Kimberly Palmer with NerdWallet recently had a water bill that topped $1,000 for three months, compared with her normal bill of about half that amount.

Kimberly joins Show Me Today to talk about what to look for when your water bill suddenly jumps and some simple ways to bring that bill back down.
