<prompt> Human: My water bill is usually 60 every month, but this month is has more than doubled to 170. I dont think we have used more water this month than any month in the past. Im going to call the city to see if this is right, but what other steps can I take to correct this? What should I ask for?  <response>: record the meter setting, turn off ALL water and recheck in an couple of hours, if there is a difference, there is an underground leak between the meter and the house.
