Main Sewer Line Installation in the South Bay
New building or a main that must be rerouted? Share plans and the existing cleanout location.
Schulze Plumbing Inc. provides Main Sewer Line Installation in the South Bay / Los Angeles County area. See cities we serve or call 310-487-2975.

Installing a main is new pipe from the building toward the public sewer or approved private system. It is a construction sequence with slope, bedding, and inspection — not a drain-cleaning visit.
ADUs and additions sometimes cannot share a failing 4-inch lateral without a new connection. We need the civil or plumbing drawings when they exist.
Common symptoms
- A new structure with no sewer yet
- A required reroute around a pool, addition, or tree
- An inspector requiring a new main instead of a patch
What this service involves
- Layout, slope, and connection to the approved tap
- Cleanouts as required
- Inspection coordination

Process
- Share new construction vs replacement route, and whether the city tap location is known, plus your ZIP code so we can confirm South Bay coverage.
- We follow up to confirm access, scope, and whether permits or other trades may be involved.
- You receive an estimate for the work you approve. We do not publish prices on this page.
- After you approve, we schedule the job.
FAQ
- Is the city tap included?
- Work on the public side follows utility rules. We estimate the private piping we are allowed to install.
- Can this wait until after landscaping?
- Better to install before hardscape. If landscaping is done, restoration is part of the scope conversation.
- ADU on the same lateral?
- Sometimes. Capacity, condition, and city rules decide. Camera the existing line before assuming a tee is enough.
