Drains & sewer services in San Diego
Drain cleaning in San Diego
UrgentIf one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.
Hydro jetting
Hydro jetting cleans the full width of a drain pipe with high-pressure water, washing out grease, scale and fine roots that a cable only punches a hole through. It works best on sound pipe and is usually done after a camera inspection confirms the pipe can take it.
Sewer camera inspection
A sewer camera inspection runs a waterproof camera through the line from your house to the city main and records what it finds: roots, cracks, sags, offset joints or collapsed pipe. It's the best way to decide between cleaning, spot repair and replacement.
Sewer line repair in San Diego
UrgentA damaged sewer line can be fixed with a spot repair, a trenchless liner, pipe bursting or an open-trench replacement. Which one fits depends on what the camera shows, how deep the pipe is, and what's on top of it, such as a driveway, trees or landscaping.
Local conditions
Drains & sewer in San Diego: what's different
Older clay sewer laterals in established San Diego neighborhoods collect roots and need periodic cleaning or repair. Many neighborhoods are built along canyons, so laterals can be long and run downhill under landscaping.
The City of San Diego Public Utilities Department provides wastewater service. A camera inspection shows where the problem is, which matters on canyon lots where access is limited.
Coastal neighborhoods like Point Loma and La Jolla also have older homes where cast-iron drains have corroded and cracked.

San Diego housing and plumbing
Older neighborhoods like North Park and Point Loma have homes from the 1920s–1950s with galvanized supply and cast-iron or clay drains; Clairemont and Mira Mesa are largely post-war and later.
Other San Diego conditions that affect plumbing
- Coastal corrosion: Salt air near the coast corrodes exposed metal fixtures and outdoor plumbing faster than inland.
- Hard water: Imported Colorado River water is hard, so scale shortens water heater life.
- Root-filled laterals: Older clay sewer laterals in established neighborhoods collect roots and need periodic cleaning or repair.
- Mild climate, hidden leaks: With few freezes, the biggest risks in San Diego are slow leaks that go unnoticed: slab leaks, running toilets and irrigation lines. Tiered water rates make finding them worthwhile.
