Soggy Yard, Low Pressure, or a Meter That Spins With the House Off: Is It the Service Line?
The service line is the pipe that brings water from the district's meter to your house. It is buried, so a leak shows up indirectly. A soggy patch in the lawn or driveway, pressure that dropped, or a meter that keeps turning with everything off are the usual signs.
A simple test separates the service line from the pipes inside the house. Close the main shutoff at the house and watch the meter. If it still moves, the leak is between the meter and the house. If it stops, the leak is inside, and the first call is a leak detection visit.
If the line is the problem, the repair is on your side of the meter. The district's meter, shutoff, and the main in the street belong to the water district.
Service Line Options: Repair, Trenchless, or Trench Replacement
| Option | How it works | Best fit | Trade-offs |
|---|---|---|---|
| Spot repair | Dig at the leak, cut out the damaged section, and replace it | One leak in a line that is otherwise sound | A second leak elsewhere on the same line is likely if the pipe is old |
| Trenchless pipe bursting | A new pipe is pulled through the old line, breaking it outward | A long run under driveways, patios, or landscaping | Needs pits at both ends, and it does not suit every soil or pipe |
| Trench replacement | The old line is dug out and a new one laid | Short lines or lines in poor condition | The most disruptive to the landscape |
| Rerouting | A new line is run on a different path | Lines blocked by structures or trees | A new path may need a permit |
The best choice depends on what the leak locator finds and what sits above the line.
Who Is Responsible for What
Responsibility generally splits at the meter. The district owns and maintains the main and the meter, and the owner is responsible for the pipe from the meter to the house. Lake Forest is served by several districts, including Irvine Ranch Water District and El Toro Water District, so check your bill for which one is yours.
If the leak is on the district's side, call the district. If the leak is on yours, it is a plumbing job. The district can also tell you whether it will adjust your bill after a documented repair. IRWD, for example, re-bills over-budget use at a lower rate after a leak is repaired.
Digging in the street or the public right-of-way usually needs a permit, and the city or district will tell you who issues it. Digging on your own property also often needs a permit, and a plumber should say who pulls it.

Where Lake Forest Water Lines Fail
Age is the main cause. The older El Toro neighborhoods date to the 1970s and 1980s, so their service lines are four to five decades old. Older lines can be galvanized steel or copper, and the plumber can tell you which you have when the line is exposed.
Hillside lots in Portola Hills can see higher pressure and ground movement, both of which stress buried pipe. Tree roots, landscaping work, and nearby construction can also damage a line.
Pressure matters. If the pressure at your house exceeds 80 psi, a regulator is needed under the California Plumbing Code, which is built on the Uniform Plumbing Code (UPC). A failing regulator can also overstress a service line.
What Affects the Cost of Water Line Repair or Replacement
Insurance sometimes covers the damage a leak causes but not the pipe itself, and some policies offer an optional service line endorsement. Check yours.

Long runs on larger lots in Bennett Ranch and Foothill Ranch mean more buried pipe to fail. Older lots in El Toro have lines that sit under mature trees and driveways.
A meter test and a pressure check come before any digging.
Water Line Questions from Lake Forest Homeowners
Close the main shutoff at the house and watch the meter. If it still moves, the leak is between the meter and the house.
In general, yes, from the meter to the house. The district is responsible for the meter and the main. Check with your district to confirm where the line of responsibility sits.
Sometimes. Trenchless pipe bursting can replace a long run with minimal digging, but it needs pits at both ends and suits certain soils.
Many districts offer adjustments after a documented repair. IRWD, for instance, re-bills over-budget usage at a lower rate. Ask yours which documents it needs.
A spot repair often takes a day. A full replacement can take a few days depending on length and surface restoration.
It is urgent. Close the house shutoff and call. A leak that floods a yard or undermines a driveway deserves a same-day call. See also slab leak repair for leaks under the house.
