In San Marcos, the pipe that runs from the Vallecitos Water District meter to your house is the property owner's to maintain, so a leak there is a job for a plumber. Typical signs are a wet strip of yard, low pressure at every fixture or a bill that suddenly rises. Call the number on this page to be connected with a local plumber in San Marcos.
San Marcos at a glance
Vallecitos Water District provides both water and sewer across San Marcos and maintains the water and sewer mains. It states that lines installed to serve private property are the property owner's responsibility, and that water services, meters and sewer laterals are installed by private contractors at the owner's expense. The median San Marcos home was built around 1994, so many lines here are relatively young; leaks often trace back to a fitting, a line stressed by grading on hillside lots, or damage from later yard projects rather than worn-out pipe.
What to do now
- If water is pouring out, close the main shutoff at the house.
- Turn off the irrigation controller so sprinklers don't confuse the meter reading.
- Check the meter. If it still moves with everything off, the leak is somewhere after the meter.
- If water is coming up at the meter box or in the street, call Vallecitos at 760-744-0460.
- Note where the ground is wet and how long it has been that way.
- Call for a plumber to locate and repair the leak on your side.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Damp strip between meter and house | Leak on the service line itself |
| Weak flow everywhere at once | Water escaping underground, or a failing pressure regulator |
| Banging pipes, dripping relief valves, worn fixtures | Pressure set too high on the house side |
| Wet spot only after sprinklers run | Irrigation valve or lateral, not the supply line |
| Meter moving but yard is dry | Leak under the slab, in a wall or at a toilet |
What affects the cost
- Pressure control. Vallecitos puts a regulator on its side of the meter where pressure tops 175 psi to protect the meter, but says that regulator does not protect the customer's line. If your pressure is high, the plumber may suggest a regulator on your side at your expense.
- Run length and slope. Long or steep runs on hillside lots take more pipe and more careful trenching.
- Surface work. Driveways, pavers and retaining walls over the line add restoration time.
- Method. A spot repair, a new section or a trenchless pull each carry different labor.
- Permits. The City of San Marcos Building Division at (760) 744-1050 handles residential permits; the plumber can confirm whether your job needs one.
