Find a Hidden Water Leak Before You Call — the Austin Meter Test Walkthrough
A silent slab leak, a stuck irrigation valve, or a worn toilet flapper can spike an Austin water bill for weeks before anyone notices. This walkthrough uses your own water meter to check for an active hidden leak in about two hours — then tells you exactly what to say when you call.
This tool provides general guidance only, not a professional diagnosis, and does not replace an on-site assessment by a licensed plumber.
The Water-Meter Leak Test
This is the same first check a licensed plumber runs on site — you can walk through the first pass yourself, for general guidance, before you ever pick up the phone.

What to Tell the Plumber When You Call
A licensed plumber can work faster with specifics. Before you call, have these ready — the more detail here, the more accurately the dispatch line can match you to a plumber with the right equipment for the job.
- Your two meter readings and roughly how much time passed between them
- Whether the leak-indicator dial was spinning with everything off
- Which fixtures, appliances, or irrigation zones were — and weren’t — running during the test
- Any warm or damp spots on the floor, unusual sounds, or wet patches in the yard
- Roughly how much your water bill has changed and over what period
- Your ZIP code, so dispatch can match you to a plumber who knows your soil and build era

Hidden Water Leaks — FAQ
Quick answers to what Austin homeowners ask most about hidden leaks.
How do I know if I have a hidden water leak?
Turn off every fixture and appliance inside and outside, note your water meter reading, wait one to two hours without using any water, then read the meter again. Any increase during that window, or a leak-indicator dial that keeps spinning with everything off, points to an active hidden leak.
Why is my Austin water bill suddenly high?
A sudden jump in an Austin water bill is often tied to a hidden leak rather than a change in usage. Common causes include a stuck irrigation valve, a worn toilet flapper, or a slab leak in the clay-soil foundations common across the metro. A water-meter test with everything off is the fastest way to check before assuming it’s just seasonal watering.
Can a slab leak dry out on its own?
No. A slab leak is a break in a water line under or within a concrete foundation, and it will not seal or dry out on its own. The seasonal expansion and contraction of Austin’s clay soils tends to keep the line under stress, and the damage typically gets worse, not better, over time.
What is the leak-indicator dial on my water meter?
Most Austin-area water meters have a small red or black triangle, star, or gear-shaped dial near the digital numbers. This dial spins in proportion to any flow, even flow too small to register on the main readout — so if every fixture is off and it’s still turning, water is moving somewhere in the system.
How long should I wait during a meter leak test?
One to two hours with zero water use anywhere on the property, inside and outside, is generally enough to catch most hidden leaks. Disable any irrigation controller first, since a scheduled cycle during the test window can create a false reading.
