Water meter leak test
A water meter leak test is a home check: shut fixtures, then watch the low-flow indicator. If it still moves, water is leaving the domestic system. That water may be under the slab, in the yard, or at a toilet. The test is a clue. It is not a slab-leak proof and not something this page can read for you.
How the home check works
Shut off irrigation at its own valve if you have one. Skip ice makers and known drips if you can. Watch the meter for a quiet minute. Movement means a leak somewhere on the house side.
Then stop. Do not start cutting a hole. Write what you saw and request a spinning-meter check if the house-side clues also point under the floor.
What a moving meter does not prove
It does not prove the leak is under the slab. A running toilet, a softener, a cooler, or a yard line on the same domestic meter can move the indicator. Separate irrigation meters — when you have one — keep landscape water out of this test.
If the meter sits still, a high bill may be a cooler, a pool autofill, guests, or a bad read. That is often the wrong page.
Valley extras that confuse the read
Evaporative coolers on older Glendale and central Phoenix houses use water in season. Pool autofills keep a waterline honest while they spend. Both can raise a bill without a warm hallway.
If the meter spins with the cooler off and every fixture closed, the supply line is the better suspect. Write that sequence. It saves the first twenty minutes on site.
What to send
Whether the indicator moved, whether irrigation is on a separate meter, and whether a floor feels warm. Two months of use help if you have them. Not required. This site cannot read your meter and is not the leak company.

Questions
Where is the low-flow indicator?
On most Valley meters it is a small triangle, star, or sweep hand on the register face. If you cannot find it, write that. A locator can still start from the bill and the floor.
Does a spinning meter always mean a slab leak?
No. It means water is leaving the domestic side. The leak may be a toilet, a yard line, or under the slab. The meter test is the start, not the mark on the floor.
Should I shut the main off for the test?
The usual home check watches the meter with fixtures off and the main still open. Shutting the house main is a different isolation. Do not force a valve you cannot operate cleanly.
What if I have a smart meter or an app reading?
Treat it as a clue, the same as a jumping bill. It is not a locate report. Write the pattern you saw.
