Commercial Plumbing
Commercial Plumbing Services in LA & Orange County, California
Fanti Sewer & Drains provides full-service commercial plumbing for offices, restaurants, retail centers, multifamily properties, medical facilities, and industrial buildings. From routine maintenance to emergency repairs, our licensed crews work around your operating hours to keep water, drain, and waste systems running with minimal disruption to your business.
This service is often a strong fit for property managers, business owners, and facility managers dealing with fixture failures, water heater issues, grease trap maintenance, backflow testing, drain and sewer problems, or code compliance repairs.
Every line is inspected before we recommend spray lining. Pipes that are collapsed, badly displaced, or structurally compromised may need a different repair approach.
What Is Commercial Plumbing?
Commercial plumbing covers the water supply, drainage, and waste systems that serve businesses, multi-tenant properties, and public-facing buildings — systems that are typically larger, more complex, and under heavier daily use than residential plumbing. Commercial properties also carry code and inspection requirements that don’t apply to a single-family home.
Our technicians handle everything from a single fixture repair to system-wide maintenance programs, working with property managers, general contractors, and business owners to plan work that fits around business hours, tenant schedules, and health-code obligations.
Whether it’s a leaking supply line behind a restaurant kitchen, a failing water heater in a multi-unit building, or a scheduled backflow test for a medical office, we scope the job before we start and give you a clear plan.
Important Distinction
Commercial plumbing isn’t just “bigger residential work.” Higher-use fixtures, grease and waste requirements, backflow prevention, code inspections, and tenant coordination all change how a commercial job needs to be planned and executed.
Depending on the property type, restaurant, retail, office, medical, industrial, or multifamily, the right approach can vary significantly even for what looks like the same repair.
Equipped for Every Type of Commercial Property
Fanti Sewer & Drains carries the equipment and licensing to handle plumbing work across a wide range of commercial property types, from single-tenant retail spaces to large multi-building complexes.
Our crews come prepared to diagnose the issue on-site and carry the parts and equipment to complete most repairs in a single visit.

Property Types We Serve
Commercial Plumbing Across Property Types
Every property type comes with its own plumbing demands, code requirements, and tenant considerations. We scope each job around the specific building we’re working in.

Restroom fixture repair, water heater service, and drain maintenance scheduled around tenant hours.

Multi-tenant plumbing coordination, shared line troubleshooting, and repairs that keep storefronts open.

Not every issue is a simple repair. Aging infrastructure, undersized lines, or systemic drainage problems may call for a broader scope of work — we’ll tell you plainly if that’s what your property needs.
Our Process
How Fanti Sewer & Drains Handles Commercial Plumbing
We treat diagnosis, scoping, scheduling, repair, and verification as one connected job, not a rushed service call.
01
Initial Assessment & Scheduling
We start by understanding the issue, the property type, and your operating hours, then schedule the visit — including emergency or after-hours service when the situation calls for it.
02
On-Site Diagnosis
Our technician inspects the fixture, line, or system in question to identify the actual cause of the problem, not just the visible symptom.
03
Scope & Options Review
Before any work begins, we walk you through what we found, what it will take to fix it, and any options if more than one approach is available.
04
Tenant & Access Coordination
For multi-tenant or occupied properties, we coordinate access, shutdowns, and timing to minimize disruption to tenants, staff, or customers.
05
Repair or Replacement Work
Our crew completes the repair, replacement, or installation using commercial-grade parts and materials suited to the property's usage level.
06
Code & Compliance Check
For work subject to inspection — backflow devices, grease interceptors, water heaters — we confirm the repair meets applicable code requirements.
07
System Testing
We test the repaired fixture or line under normal operating conditions to confirm the issue is resolved before we consider the job done.
08
Cleanup
Work areas are cleaned and restored, with particular attention to food service, medical, and other sensitive environments.
09
Documentation
We provide documentation of the work performed, useful for property records, tenant communication, or compliance files.
10
Follow-Up & Maintenance Planning
For properties that want it, we can set up a recurring maintenance schedule to catch issues — like grease buildup or aging fixtures — before they become emergencies.
