Who We Are
Honest, licensed plumbing — built on a different kind of service.
Sewer Pipe Pros Inc. was built by Robert Manuel Chamul on a simple idea: plumbing work should be upfront, explained, and done right the first time. Too many LA homeowners have been burned by vague pricing, pushy upsells, and techs who disappear the moment a warranty claim comes in.
We run things differently. Every job starts with a real diagnosis. Every price is explained before we pick up a wrench. Every service — from a toilet reset to a full trenchless sewer replacement — is performed by a licensed team that treats your home like their own.
We're a Greater Los Angeles contractor holding both a C36 plumbing license and a C42 sanitation systems license — which means we can legally (and competently) handle everything from your kitchen sink to your main sewer line.

The difference is in how we work.
Six things every Sewer Pipe Pros customer can count on — whether you're calling us for a slow drain or a full repipe.
Honest Upfront Pricing
Flat-rate quotes approved before any tools come out. No hourly creep, no mystery upsells, no vague change orders at the end.
Fast, Respectful Service
Same-day response on most calls. Our techs show up on time, wear shoe covers, lay drop cloths, and leave the site cleaner than we found it.
Full-Service Plumbing
From a dripping faucet to a full trenchless sewer replacement — one team, one warranty, no hand-offs to a subcontractor.
Modern Technology
HD sewer cameras, hydro-jetters, pipe locators, electronic leak detection — we invest in the tools that actually solve problems, not just find them.
Residential & Commercial
Single-family, condo, ADU, multifamily, restaurants, retail — we scope the work to the property type and code requirements.
License & Credentials
A license for every part of the job.
Most plumbers hold a C36. A C42 license adds the authority to handle sanitation systems — sewer laterals, leach fields, and other drain work regulated by the state. Holding both means we can legally (and competently) take a job from the sink to the city tap.
