Main Line Clog Clearing
When toilets gurgle and the tub fills as the washer drains, the main line is blocked, usually by roots at a clay joint.

The City of San Fernando packs a lot of older houses into a small street grid, and their sewer laterals and supply pipes show it. When a drain backs up or a pipe leaks, call us any hour.
Plumbing in San Fernando, in short
San Fernando calls lean toward sewer lateral clogs and root intrusion, galvanized pipe that has rusted nearly shut, water heater swaps and gas line repairs. We clear or camera the line, show you what we find, and explain repair options and typical costs before work starts. Permits go through the city, not LADBS.
How we cover San Fernando
San Fernando is a separate small city surrounded on every side by the City of Los Angeles, with Pacoima, Sylmar and Mission Hills along its borders. It has a compact grid of streets around San Fernando Road and Brand Boulevard, and a large share of its houses were built before the 1960s.
Because it is a separate city, the rules are different. San Fernando runs a city water system drawing on local wells, so LADWP is not your supplier, and permits come from the city's building office. We work both sides of the line every week and plan each job around the right agency.
Homes and pipes
Older houses and pipes in San Fernando
- Pre-war bungalows and cottagesMany blocks near the old downtown have small houses from the early and middle 1900s on raised foundations, with crawlspace access to drains and supply lines.
- Galvanized supply linesOriginal galvanized steel pipe is still common, and it narrows with rust until a single faucet barely runs.
- Clay sewer lateralsLaterals from this era are usually clay, and the joints let in roots from the mature trees that shade many streets.
- Back houses and added unitsSome lots have a second dwelling or converted garage sharing one sewer lateral, which puts more load on an older line.
What people call about
What San Fernando homeowners call us about
Sewer Camera Inspection
After clearing a line we send a camera down so you can see cracks, offsets or sags before deciding on a repair.
See the detailsWhole-House Repiping
Galvanized pipe in houses this old usually needs replacing as a whole, and crawlspaces make a repipe simpler than in a slab house.
See the detailsWater Heater Replacement
Older heaters in closets and service porches often lack proper straps or venting, which we correct during the replacement.
See the detailsGas Line Repair
Old black iron gas pipe and outdated flex lines on stoves and dryers are common, and any leak has to be fixed before SoCalGas restores service.
See the detailsADU Plumbing
Owners adding a back unit need new water, gas and sewer runs sized for two households instead of one.
See the detailsSewer laterals and repipes in an older small city
Most sewer trouble in San Fernando starts at the lateral, the pipe between your house and the city main. Clay pipe lasts a long time, but joints loosen as the ground moves and roots find the gaps. Clearing the line restores flow, and the camera footage tells us whether a section repair or a full replacement makes more sense. Our guide to clay pipe and roots covers the warning signs.
Repiping is the other big project here. If your pressure is weak, the water runs brown after a trip away, or you have had more than one pinhole leak, the galvanized lines are probably past saving. Read patch, partial or full repipe to weigh the choices. In a raised-floor house we run new copper or PEX through the crawlspace with fewer wall openings.
If you are planning a garage conversion or back unit, think about plumbing early. The existing lateral may need upsizing or a new cleanout, and the gas service may need a larger meter. We can walk the lot and tell you what is involved before the design is final.
Questions we hear
Questions from San Fernando
Is San Fernando served by LADWP?
No. The City of San Fernando operates its own water utility, so billing, meter and main shutoff questions go to the city. Neighboring areas like Pacoima and Sylmar are in the City of Los Angeles and use LADWP. We work on both sides and know which rules apply at your address.
Why does my San Fernando house keep getting sewer backups?
Recurring backups in an older house usually mean roots or a broken joint in the clay lateral. Snaking clears the pipe, but roots grow back. A camera inspection shows the condition of the line so you can decide between scheduled maintenance, a spot repair or replacing the lateral.
Do plumbing permits in San Fernando go through LADBS?
No. San Fernando is a separate city with its own building and safety office. Water heater replacements, repipes, gas work and sewer replacements are permitted there, with city inspections. We handle the paperwork and schedule the inspection, so you are not stuck figuring out which office to call.
How long does a repipe take in a San Fernando bungalow?
A single-story San Fernando house on a raised foundation typically takes a few working days for a full repipe, plus time for the inspection and patching. We restore water overnight whenever we can, so you are not without a shower for the whole job. Slab houses take longer because the lines go through walls and the attic.
