Meter Test
How to Determine if You Have a Hidden Water Line Leak
The meter test is a great at-home indicator to gauge potential water line leaks.
1. Conduct this test for 30 minutes, during which time no water is being used on the property.
2. Find your water meter.
3. Check triangle or star-shaped leak indicator for movement. If it spins, this indicates a possible leak on a water line. Proceed to Step 4.
4. Write down the numbers indicated on the meter at the start of this test.
5. Return to check the meter reading in 30 minutes.
6. If the numbers did not change, you don’t have a leak in your pressurized water system. If the numbers have changed, continue with the following steps.
7. Shut off the valves under every toilet in the house and repeat steps 1-4.
8. If the number has changed, this indicates water consumption even though water was not being used during the test. You may need a leak detection assessment.
