Drain Stack Replacement & Relocation in the South Bay
A leaking stack in a chase, or a remodel that deletes the wet wall — request an estimate.
Schulze Plumbing Inc. provides Drain Stack Replacement & Relocation in the South Bay / Los Angeles County area. See cities we serve or call 310-487-2975.

A drain stack is the vertical highway for waste and vents. Replacing it is a multi-floor problem in duplexes and apartments. Relocating it is a remodel problem when the new plan puts a closet where the chase was.
We coordinate shut-downs so upstairs units are not surprised. Firestopping and supports are part of a real stack job.
Common symptoms
- Leaks at stack joints between floors
- A remodel that moves all the baths
- A camera showing a failed vertical section
What this service involves
- Mapping fixtures on the stack

FAQ
- Can one floor be done at a time?
- Sometimes. Offsets and fittings may still require opening the floor above or below.
- Is this the same as a lateral?
- No. The stack is in the building. The lateral is typically in the ground outside.
- Do vents move too?
- Usually. A stack is a waste-and-vent assembly, not only a waste pipe.
