Signs a Buried Water Line Has Failed
Emergency water line repair in Mission Viejo, CA covers the supply pipe that runs underground from the water meter to the house. A leak there never shows on a ceiling. It shows in the yard, on the meter and on the bill.
- A wet or sunken patch of lawn, or a soggy spot on the driveway edge, with no irrigation running.
- Water pressure that drops with no other cause.
- A meter that moves with every fixture and the irrigation off.
- A water bill that rises with no change in habits.
- The sound of running water when the house is quiet.
EPA WaterSense gives a simple test. Check the meter before and after two hours when no water is used, and if the reading changes there is probably a leak. The test says there is a leak, not where it is.
Who Owns Which Part
The water district owns the main in the street and the meter. The line from the meter to the house and everything inside is generally the owner's. A leak at the meter or before it is the district's to fix, and one after it is yours.
Santa Margarita Water District and Moulton Niguel Water District serve different parts of South Orange County, as do others. Your bill names the district. Call it if you think the leak is at the meter, and call a plumber for anything after.
Shut the house valve and watch the meter. If it keeps moving, the leak is on the buried line between the meter and the house, or at the meter itself. If it stops, the leak is inside the house. This test saves a lot of confusion.
Repair or Replace the Line
| Method | How it works | Fits when | Trade-off |
|---|---|---|---|
| Spot repair | Dig at the leak and replace a short section | One failure in an otherwise sound line | Digging at that spot |
| Open trench replacement | Dig the full run and lay new pipe | The pipe is old, corroded or has many leaks | Landscape and hardscape repair after |
| Trenchless replacement | Pull new pipe through the old path from small pits at each end | The route is under a driveway, patio or mature landscaping | Needs access pits and a suitable route |
| Reroute | Abandon the old line and run a new one on a clear path | The old line is under a structure | A new path must be available |
A line that has leaked several times is a candidate for replacement. A line with one clean failure may only need a section. Ask the plumber to show you the pipe after it is exposed.
What Else Gets Checked
A buried line fails for a reason. Pressure above 80 psi is a common stress, and California plumbing practice calls for a regulator when the area pressure is higher, according to the City of San Diego. A plumber should read the pressure and check the regulator and the main shutoff valve.
If water has reached the foundation, a slab or a garage floor, see slab leak repair and water damage restoration. A burst section inside the house is covered under burst pipe repair.
What Affects the Cost
- Length and depth of the line.
- What is above it, such as lawn, concrete or pavers.
- Method chosen: spot, trench or trenchless.
- Pressure regulator or valve replacement.
- Permits, and the district's inspection of connections near the meter.
