If a pipe bursts in a San Marcos home, shut the main water valve right away and keep away from wet outlets. A plumber can then locate the break, replace the damaged section and check whether high pressure played a part. Call the number on this page to be connected with a local plumber in San Marcos.
San Marcos gets water and sewer service from Vallecitos Water District, reachable at 760-744-0460. Vallecitos maintains the water and sewer mains; the lines serving private property are the owner's responsibility. With a median build year of 1994, much of the city's housing is relatively young, so bursts here more often come from fittings, valves, appliance hoses and pressure than from worn-out pipe.
Pressure deserves special attention. Vallecitos notes that where pressure exceeds 175 psi it installs a regulator on its side of the meter to protect the meter, and that this regulator does not protect the customer's line. A pressure regulator on the house side may be needed, at the owner's expense.
What to do right now
- Close the main shutoff. If it won't turn, close the valve at the meter box.
- Shut off power to an electric water heater, or set a gas unit to pilot.
- Open a low faucet or hose bib to drain the remaining water.
- Turn off breakers to wet rooms if you can reach the panel from a dry spot.
- Move furniture, rugs and electronics out of the water.
- Take photos and video before you start cleaning up.
- If water is coming up at the meter or in the street, call Vallecitos.
Symptoms and likely causes
| What you see | Likely cause |
|---|---|
| Washer or toilet hose suddenly gushing | Worn or kinked supply hose |
| Several leaks at joints in a short time | Pressure too high, regulator missing or failed |
| Water spreading from under a cabinet | Failed angle stop or compression fitting |
| Wet strip of lawn toward the street | Break in the service line from the meter |
| Warm spot on a slab floor | Hot water line leak under the concrete |
What affects cost
- Location. Hoses and fittings are quick; pipe in walls, ceilings or slab takes longer.
- Pressure work. Adding or replacing a house-side regulator is a separate part of the job.
- Digging. Yard line repairs mean excavation and backfill.
- Permits. The City of San Marcos Building Division handles residential permits for larger work, and its residential packet requires homes built on or before January 1, 1994 to replace noncompliant fixtures when permitted work is done.
- The hour. Nights and weekends usually cost more.
