California Building Code

California Plumbing Code requires sewer laterals to maintain a minimum 1/4-inch-per-foot slope, use approved materials (ABS, PVC, or cast iron), and include a two-way cleanout at the property line or within 5 feet of the building. Repairs require permit and inspection.

Project Timeline

Camera Inspection & Diagnosis

1-2 hrs

Insert a sewer camera through the cleanout to video-inspect the entire line. Identify cracks, offsets, root intrusion, bellies, and collapses. Locate the lateral with a transmitter sonde.

Excavation & Pipe Exposure

2-4 hrs

Dig down to the damaged section using a mini excavator or hand tools. Depth is typically 3-6 feet. Call 811 before digging to mark underground utilities.

Pipe Repair or Replacement

2-4 hrs

Cut out the damaged pipe section, install new ABS/PVC pipe with proper fittings and slope (1/4 inch per foot), and add a cleanout if one doesn't exist.

Backfill, Compaction & Restoration

2-3 hrs

Backfill the trench with clean fill in lifts, compact each layer, and restore the surface (soil, concrete, or asphalt patch). Final camera inspection to verify the repair.

Sewer Line Repair in San Francisco — FAQ

How do I know if my sewer line needs repair?+

Warning signs include slow drains throughout the house, gurgling toilets, sewage odor in the yard, wet spots in the lawn, and recurring backups. A camera inspection confirms the diagnosis.

What's the difference between traditional and trenchless sewer repair?+

Traditional repair involves digging a trench to access the pipe. Trenchless methods (pipe bursting or CIPP lining) require only small access pits. Trenchless costs 20-40% more but saves landscaping and hardscape restoration costs.

How long does a sewer line repair take?+

A spot repair (5-10 feet) takes 1 day. A full lateral replacement (30-80 feet) takes 1-2 days. Trenchless pipe bursting is typically completed in 1 day.

Does homeowner's insurance cover sewer line repair?+

Standard homeowner's insurance rarely covers sewer line repair due to wear, roots, or age. Some policies offer a 'service line' endorsement for an additional premium. Check with your insurer before starting work.

Why do older NorCal homes have sewer problems?+

Homes built before 1980 often have clay or Orangeburg (tar paper) sewer lines. Tree roots penetrate clay joints, and Orangeburg collapses over time. These materials have a 50-60 year lifespan and are now past their useful life.
