Signs of a yard leak
- A soggy patch of lawn or a puddle when no sprinkler has run.
- A section of grass that is greener or growing faster than the rest.
- A wet strip along a driveway, a sidewalk or a foundation.
- The sound of running water outside when the house is quiet.
- A water bill that rises with no change in how you live.
- Lower water pressure at hose bibs and sprinklers.
These signs do not always mean a leak. Overwatering, a stuck sprinkler valve and a running toilet can produce similar bills. The meter test below separates real leaks from heavy use.
The meter test
- Turn off every tap, appliance and sprinkler so no water is being used.
- Open the meter box, usually near the street, and find the flow indicator, a small triangle or dial on the meter face.
- If the indicator is turning with everything off, water is moving somewhere.
- Close the sprinkler anti-siphon valve, if you have one. If the indicator stops, the leak is in the sprinkler system.
- Close the main valve at the house. If the indicator still turns, the leak is between the main valve and the meter.
- If the indicator stops when the main valve is closed, the leak is inside the house or between the house valve and the fixtures.
Write down the meter reading, wait an hour with no water used and read it again. Any change is a leak. These steps follow the meter guide that the City of Port Hueneme publishes for customers.
Port Hueneme note: reading the city meter and who to call
The City of Port Hueneme Water Division serves about 6,500 connections. Its meter guide says the meter reads in hundred cubic feet, called HCF, and that one HCF is 748 gallons. The leak test above comes from that guide, which also tells customers to close the sprinkler valve and then the home's main valve to narrow the source. The city asks you to call the Water Division at 805-986-6563 if you suspect a leak.
The city water page we read on October 29, 2026 said Stage 1 water restrictions were in effect until further notice, so check the page for current rules before you adjust your sprinklers. State rules also prohibit watering that causes more than incidental runoff and watering within 48 hours after at least a quarter inch of rain.
Where yard leaks usually hide
| Source | Clue | Who fixes it |
|---|---|---|
| Sprinkler line or valve | Meter stops when the sprinkler valve closes | Irrigation repair or a plumber |
| Hose bib or outdoor fitting | Drip or wet wall near the spigot | Plumber |
| Service line, meter to house | Meter turns with the house main closed | Plumber, with the city if at the meter |
| Line inside the house | Meter stops when the house main closes | Plumber, see leak detection |
| Drain or sewer line | Smelly wet area, not clear water | Plumber, see sewer line repair |
What you can fix and what you should not
A cracked sprinkler head or a loose fitting is a small repair many owners handle. A leak in a buried service line is different. The pipe may be deep, there may be other utilities nearby, and a wrong dig can cause more damage. A locator can find the leak to within a small area, which keeps digging small.
We could not find a Port Hueneme rule that says who owns the service line between the meter and the house. The California Contractors State License Board describes plumbing work on water piping from the owner's side of the utility meter to the structure, which fits the common understanding that the house side is the owner's. Ask the Water Division if you are unsure about a specific leak near the meter.
Meter still turning with everything off?
Call and tell us what the meter test showed. We locate the leak and explain the repair.
How we find a buried leak
We combine a pressure test, acoustic listening and, where it helps, thermal imaging and tracer gas. Each narrows the area. We mark the spot, tell you the likely depth and explain the repair choices. When a long section is failing, replacement may be a better choice than a patch, and we explain both with prices before we dig.
Our crews cover Port Hueneme, Oxnard and Channel Islands Beach. Meter questions in Channel Islands Beach go to the Community Services District, which runs water there instead of the city.
After the repair
Simple checks before you dig
Do not start digging on a hunch. A wet patch of lawn can be several feet from the real leak because water follows the easiest path through soil and along the outside of the pipe.
Turn off every fixture and look at the meter again after ten minutes. A moving dial or a spinning low-flow indicator confirms water is leaving the system somewhere.
If the dial stops when you close the main valve at the house, the leak is between the meter and the house. That narrows the search to the service line, and a plumber can then locate the spot with listening gear before any digging starts.
Run the meter test again with everything off to confirm the leak is gone. If you were billed for water that leaked, call Utility Billing at 805-986-6524. We did not find a published leak adjustment policy, so ask the city directly and keep your repair paperwork and the bills from before and after.
Questions Port Hueneme homeowners ask
Turn off all water use, open the meter box and watch the flow indicator. If it turns, water is moving. The city meter guide describes closing the sprinkler valve and then the house main to find which side the leak is on.
It stands for hundred cubic feet. The city says one HCF equals 748 gallons.

No. A stuck sprinkler valve, a leaking hose bib or overwatering can look the same. The meter test separates them.
