Commercial Drain & Sewer
Heavy-duty drain cleaning, hydro jetting, and sewer line services for restaurants, HOAs, and commercial properties.
Professional Commercial Drain & Sewer in Orange County
Commercial drain and sewer systems handle far more volume than residential systems, and the consequences of failure are more severe — business disruption, health code violations, property damage, and liability. KCB Plumbing provides heavy-duty drain cleaning, sewer maintenance, and urgent same-day service for restaurants, retail centers, HOAs, and other commercial properties across Orange County.
Restaurants face unique challenges with grease accumulation in drain lines. Retail and office buildings deal with high-volume restroom usage. HOAs manage large shared sewer systems that serve multiple units. We understand these different environments and tailor our approach accordingly, using commercial-grade hydro jetting equipment, professional root cutting tools, and sewer cameras to keep your drain systems flowing.
Preventive maintenance is especially important for commercial properties. A drain backup during business hours affects operations, customer experience, and potentially health department compliance. Our commercial maintenance contracts include scheduled cleanings, camera inspections, and priority response during business hours — preventing problems before they disrupt your business.

How It Works
System Assessment
We evaluate your commercial drain system, identify high-risk areas, and determine the appropriate cleaning method.
Camera Inspection
Sewer cameras inspect the main lines and key branch connections to assess condition and locate problem areas.
Cleaning
Using commercial hydro jetting (up to 4,000 PSI), mechanical rooters, or both, we thoroughly clean all affected lines.
Grease Management
For restaurants, we clean grease interceptors and inspect grease lines to prevent buildup-related backups.
Maintenance Plan
We recommend a cleaning schedule based on your property's usage patterns and risk factors.

Common Questions
Commercial Drain & Sewer FAQ
How often should commercial drains be cleaned?
It depends on the property type. Restaurants should have grease lines cleaned monthly and main drains quarterly. Office buildings and retail spaces typically need annual cleaning. HOA shared sewer systems benefit from semi-annual maintenance. We create a custom schedule based on your needs.
Do you service grease traps and interceptors?
Yes, we clean grease traps and interceptors as part of our commercial drain service. For restaurants, regular grease trap maintenance is essential for health code compliance and preventing sewer line backups.
Can you set up a maintenance contract?
Absolutely. Our commercial maintenance contracts include scheduled cleanings at the frequency your property needs, priority response during business hours, and camera inspections. Contracts lock in pricing and ensure you never miss a maintenance cycle.
What if I have an urgent drain backup during business hours?
We prioritize urgent commercial calls during business hours (Mon–Fri 8 AM – 5 PM) because we understand the business impact. Our goal is to have a technician on-site as quickly as possible with the equipment needed to restore flow and get your operations back to normal.
