Underfloor Drain Line Replacement in the South Bay
Crawlspace leaks, sagging ABS, or a failed cast-iron run under the floor — request an estimate.
Schulze Plumbing Inc. provides Underfloor Drain Line Replacement in the South Bay / Los Angeles County area. See cities we serve or call 310-487-2975.
Underfloor drains are the horizontal piping you can sometimes see from a crawlspace or basement. Replacing a sagged ABS run or rusted cast-iron is cleaner than cabling a belly every month.
Peninsula hillside homes with stepped floors make these runs longer. Access hatches matter; we will tell you if we need a new opening.
Common symptoms
- Drips onto crawlspace soil when a fixture drains
- A camera showing a belly between fittings
- Cast-iron flakes in the trap
What this service involves
- Mapping the run and supports
- Replacing the failed piping with proper slope and hangers
- Tying back into stacks and cleanouts

FAQ
- Can you work in a tight crawlspace?
- Often, with access. Some jobs need a better opening. Photos of the hatch help.
- Will this stop the backups?
- If the backups were from that broken or belly section, yes. A downstream lateral problem would still need that page.
- Do you replace vents too?
- If they are in the same failed assembly and approved in the scope.
