Underground Water Lines in the South Bay
A wet yard over a water line, or a new buried run to a garage? Request an underground water-line estimate.
Schulze Plumbing Inc. provides Underground Water Lines in the South Bay / Los Angeles County area. See cities we serve or call 310-487-2975.

Underground water lines need depth, tracer, and protection under paving. A leak here can look like a sprinkler problem. We confirm it is potable plumbing before we dig a landscape trench for no reason.
Remote ADUs and studios often need a dedicated buried line with its own shutoff.
Common symptoms
- A mysterious wet strip in the yard
- A meter that spins with interior valves off
- A new structure that needs water across the lot
What this service involves
- Locating and confirming the line
- Repairing or installing buried potable pipe
- Shutoffs and testing before backfill

FAQ
- Irrigation leak?
- If it is irrigation, a landscaper may own it. If it is the house service, it is us. We will say which.

- With required separation. We will not bundle illegally.
- Can you bore under a drive?
- Sometimes. Open cut is the other option. Access decides.
