Water Heater Repair
Hard water sediment, worn thermocouples and failing gas valves cause most heater outages here, and many tanks can be repaired if the tank itself is sound.

A water heater that keeps losing its pilot, a gas line to a barn or detached garage, or a long water main leaking under a horse property: those are typical Sylmar calls, and we answer them around the clock.
Plumbing in Sylmar, in short
Sylmar sits at the north end of the Valley where the 5 and 210 meet, with older flatland houses, foothill tracts and larger horse-keeping lots. Common calls are water heater repairs and replacements, gas lines to outbuildings, seismic gas shutoff valves, long water mains and clay sewer laterals. We test, find the fault and make the repair on the spot.
How we cover Sylmar
Sylmar is the northernmost neighborhood in the City of Los Angeles, set against the San Gabriel foothills where the Golden State and Foothill freeways meet. Housing ranges from postwar single-story houses on the flat streets to newer tracts climbing toward the hills, along with properties zoned for horses that have barns, arenas and long driveways.
The area also sits close to faults that have shaken the northern Valley hard, and the 1994 Northridge earthquake broke water heaters and gas connections across the region. That history is why we pay close attention to water heater straps and flexible gas connectors here, and why many Sylmar owners ask about automatic shutoff valves at the meter.
Homes and pipes
Houses, lots and pipes across Sylmar
- Flatland postwar housesSingle-story homes on the lower streets date mostly from the 1950s and 1960s and often still carry galvanized supply lines and clay laterals.
- Foothill tracts on sloped lotsNewer subdivisions toward the hills sit on sloped lots, which affects sewer fall, water pressure and how far a main runs to the house.
- Horse properties and outbuildingsLarger lots often have barns, wash racks, hose bibs and detached garages fed by long buried water and gas lines.
- Wildfire and wind exposureFoothill streets sit near brush and see strong seasonal winds, so outdoor fixtures, exposed lines and vent caps take a beating.
What people call about
What Sylmar homeowners call us for
Seismic Gas Shutoff Valve
With active faults nearby, many owners add an automatic shutoff at the meter so gas stops if a strong quake hits while no one is home.
See the detailsGas Line Installation
Barns, workshops, outdoor kitchens and pool heaters on bigger lots all need gas lines sized for the distance and the load.
See the detailsMain Water Line Replacement
Long mains to houses set far back on horse properties leak underground, and old galvanized runs often have more than one failure.
See the detailsOutdoor Spigot Repair
Hose bibs at barns, arenas and wash racks get heavy daily use and wear out faster than the ones on a typical suburban lot.
See the detailsPressure Regulator Replacement
Lower streets can carry high incoming pressure, and a failed regulator shows up as banging pipes, running toilets and dripping relief valves.
See the detailsGas and water heater safety on Sylmar properties
Most Sylmar gas work involves longer runs than elsewhere in the Valley. A line from the meter to a barn, a pool heater and a back-unit kitchen has to be sized for its full length and every appliance on it, or the far appliance starves when everything runs at once. We pressure test existing lines, replace corroded steel with coated pipe or approved flexible line, and pull LADBS permits. After a gas leak repair, SoCalGas may need to restore service at the meter.
Water heaters here should be strapped twice, in the upper third and lower third, with flexible gas and water connectors so the tank can shift slightly without breaking a line. We also check that the relief valve drains to a safe spot outside. If you're replacing an older tank, the comparison in our water heater options article covers what fits a Sylmar garage.
Foothill properties also benefit from shutoffs you can find in the dark, so we tag the main water valve, the gas meter shutoff and each fixture valve when we finish a job. We reach Sylmar quickly from the 5 or 210 and also cover nearby Granada Hills and Santa Clarita across the pass.
Questions we hear
Questions from Sylmar
Should I install a seismic gas shutoff valve on my Sylmar home?
Many Sylmar owners do, given how close the area sits to active faults. An automatic valve at the meter stops gas when strong shaking hits, which can prevent a fire from a broken connector. It does mean someone has to reset it afterward. Typical installed ranges are $450 to $900, not a quote, plus any permit and gas company requirements.
Can you run a gas line to a barn or workshop in Sylmar?
Yes. We measure the distance from the meter, add up the appliances the line will feed, and size the pipe so the far end gets enough pressure. Buried lines go in at the required depth with tracer wire. We pull the permit, pressure test for the inspector, and coordinate with SoCalGas if the meter needs upsizing for the added load.
Why does my Sylmar water heater keep losing its pilot?
The usual causes are a worn thermocouple, a dirty pilot assembly, a weak gas valve, or poor combustion air in a tight closet or garage. Strong wind can also push down a vent cap that isn't sized or placed right. We test each part, replace the failed one, and check the venting before we leave so the problem doesn't return on the next windy night.
How do you find a water main leak on a Sylmar horse property?
We confirm the leak with the meter, then isolate sections using valves at the house and outbuildings where they exist. Acoustic listening and line tracing narrow down the spot along the run. On long galvanized mains with several leaks, replacing the whole line is often cheaper than repeated digs across the property.
