Why Is My Water Bill Suddenly So High?
A suddenly high water bill in Nampa can come from a hidden leak, a running toilet, extra irrigation, seasonal use or a billing issue, so this guide for 83651, 83686 and 83687 homeowners separates those causes with a meter test before assuming a leak near Downtown Nampa.
Does a high water bill always mean a leak?
No. A leak is one possible cause, but irrigation use, seasonal changes, running toilets and meter or billing issues can also affect usage. Compare usage in gallons or cubic feet, not just the dollar amount, check for a running toilet with a dye or listening test, review irrigation run times, then do the meter test. Only then does a leak become the leading explanation.

An unexplained water bill is a clue, not a diagnosis. Compare usage in gallons rather than dollars, check for a running toilet and irrigation run times, then do the meter test.
Water meter running with all taps off
A water meter running with all taps off is the test that turns a bill question into a leak question, because it proves water was used with nothing running.
