The water meter is the most reliable way to confirm a hidden leak in a Compton home. The City of Compton bills water and sewer on the same monthly statement, so a leak raises both line items at once. Many Compton homes built in the 1940s through 1970s have original copper plumbing that is now 50 to 80 years old, making slab leaks and pinhole leaks common sources of unexplained high bills.
Run this test late at night when no water is being used. The longer the window, the smaller the leak you can detect. Two hours is the minimum; overnight is better.
How to run the meter test
- Turn off every water fixture and appliance in the home, including the irrigation system and ice maker.
- Locate your City of Compton water meter at the curb. Lift the lid and read the current number. Meters show either gallons or HCF (hundred cubic feet).
- Note whether your meter has a small low-flow indicator (a triangle or star wheel). If it spins with everything off, you have an active pressurized leak right now.
- Wait at least 2 hours without using any water.
- Read the meter again and enter both readings below.

Frequently asked questions
How do I run a meter leak test in Compton?
Turn off every fixture and appliance. Locate your City of Compton meter at the curb, note the reading, wait at least 2 hours without using any water, and read the meter again. Any movement confirms a pressurized leak somewhere in the system.
Does the City of Compton bill water and sewer together?
Yes. Unlike some nearby cities where sewer is a separate annual property tax charge, the City of Compton bills water and sewer on the same monthly statement. A hidden leak raises both line items at once.
What causes a high Compton water bill with no visible leak?
Common causes include a slow toilet flapper, a dripping faucet, an irrigation line leaking underground, or a slab leak in older copper plumbing. Because Compton homes built between the 1940s and 1970s still have original copper, slab leaks are especially common here.
Can a slab leak cause a high water bill in Compton?
Yes, and it is one of the most common causes in this city. A slab leak runs continuously under the concrete slab, adding to both the water and sewer portions of your monthly City of Compton bill without any visible drip. If the meter test confirms a leak and no fixture is the source, call (424) 544-0235 for professional acoustic or thermal detection.
