Roanoke Valley Commercial Kitchen & FOG Compliance Specialists

Commercial Grease Trap Installation, Repair & Hydro Jetting in Roanoke, VA — Protect Your Kitchen from Costly Downtime

In a commercial restaurant or commercial food production facility, plumbing lines endure punishing conditions. Every day, gallons of hot fats, oils, and grease (FOG), along with food solids and dish soap, flow into your drainage system. When grease cools inside pipes, it solidifies into dense, rock-hard obstructions that regular snaking cannot clear. A mid-dinner backup doesn't just mean a call to a plumber—it means lost tables, health department citations, and thousands of dollars in lost revenue. At RCR Plumbing LLC, we keep Roanoke kitchens operating cleanly with precision grease interceptor installations, comprehensive baffle repairs, and industrial-strength hydro jetting that scours pipes back to their bare internal walls.

Fats, Oils & Grease (FOG): The #1 Threat to Your Commercial Plumbing

Western Virginia Water Authority (WVWA) FOG Regulations: Municipal authorities aggressively monitor public sewer laterals for commercial grease discharge. Improperly sized or unmaintained grease traps lead to formal compliance violations, surcharges, and costly cleanup assessments from the municipality.
Health Inspection Shutdowns: When kitchen floor sinks or dish pit lines back up, food prep must stop immediately under Virginia Department of Health regulations.
Grease Vapor & Odor Intrusion: Failing gaskets, missing vent traps, or cracked interceptor baffles allow rancid grease and hydrogen sulfide odors to drift into dining areas, driving away customers.
Why Traditional Augers Fail on Grease: A mechanical cable merely punches a temporary 1-inch hole through thick grease. Within 48 to 72 hours, cooling fats collapse back in, plugging the line completely.

Engineered Solutions for Commercial Kitchens & Facilities

Commercial High-Pressure Hydro Jetting (Up to 4,000 PSI)

What It Does: Our truck-mounted and commercial portable jetting units blast water at up to 4,000 PSI and 12+ GPM through specialized rotating cutting nozzles.
The Result: Completely emulsifies thick grease cakes, strips scale from cast iron walls, and flushes sludge out to the municipal connection, restoring the pipe's full original diameter.
Off-Hours Execution: We perform routine jetting before kitchen prep opens in the early morning or after closing hours at night to ensure zero disruption to your kitchen staff.

Grease Trap / Interceptor Installation & Sizing (Indoor & Outdoor)

Point-of-Use Under-Sink Traps: Sizing and installation of compact stainless steel or polyethylene hydromechanical grease interceptors (HGI) directly under 3-compartment pot sinks, prep sinks, and pre-rinse dish tables.
Large-Capacity In-Ground Exterior Interceptors: Sizing, permitting, excavation, and installation of 500-gallon to 2,000+ gallon exterior gravity grease interceptors (GGI) for high-volume restaurants, bakeries, and institutional facilities.
Code Calculation: We calculate fixture flow rates (GPM) and grease retention capacity in accordance with current Virginia plumbing codes.

Baffle Repairs, Gasket Replacements & Sampling Port Installation

A grease trap is only effective if its internal baffles are intact to slow incoming water and allow separation. Broken, corroded, or missing baffles allow raw grease to pass straight into the sewer.
We replace rusted cast iron flow diverters, install airtight neoprene replacement gaskets to eliminate kitchen odors, and add municipal-compliant effluent sampling ports.

Preventative Jetting Maintenance Agreements

Don't wait for your dish pit to back up on a Friday night. We engineer custom quarterly or bi-annual hydro jetting schedules tailored to your seating capacity, menu fat content, and pipe pitch.
Includes before-and-after digital camera inspection logs for your facility records.

Built for the Realities of Roanoke's Food Service Industry

From bustling farm-to-table kitchens in Downtown Roanoke to family-owned diners in Salem and fast-casual franchises along Williamson Road, commercial kitchens operate on narrow margins and strict timetables.

At RCR Plumbing LLC, we don't treat your restaurant like a residential service call:

Commercial Master Plumber Licensing: We pull commercial permits, collaborate seamlessly with municipal inspectors, and ensure your system passes Western Virginia Water Authority standards on the first try.
Dedicated Equipment: We maintain commercial-grade jetters with grease-cutting warthog nozzles, heavy-duty snakes, and waterproof cameras specifically designated for food service grease lines.
Emergency Priority Routing: A kitchen backup is a commercial emergency. We respond with urgency to get your drains clearing and your staff back to cooking.

How often should a commercial kitchen have its lines hydro jetted?

For high-volume restaurants, BBQ establishments, or facilities doing heavy frying, preventative hydro jetting should be performed every 3 to 6 months to prevent catastrophic grease accumulation. Lighter-volume cafes or sandwich shops typically require annual preventative jetting. RCR Plumbing designs custom preventative maintenance plans based on your facility's menu and pipe layout.

What is the difference between pumping a grease trap and hydro jetting?

Pumping removes accumulated FOG and water from the grease trap reservoir itself using a vacuum truck. Hydro jetting scours the actual incoming drain pipes from your kitchen sinks to the trap, as well as the outlet line from the trap to the city sewer, blasting away the hardened grease scale that vacuum pumping cannot reach. Both are essential for complete kitchen drainage health.

Why does my grease trap smell so bad inside the kitchen?

Persistent grease odors inside the kitchen usually point to a dried-out or deteriorated lid gasket, loose cover bolts, a cracked flow control vent, or a missing air admittance valve. RCR Plumbing replaces worn rubber seals, tests venting configurations, and inspects internal baffle integrity to eliminate noxious fumes.

What size grease trap does the City of Roanoke or WVWA require for a new restaurant?

Grease trap sizing is determined by the total number and drainage fixture-unit (DFU) value of all connected sinks (3-compartment, prep, hand wash) and commercial dishwashers, along with local municipal retention time formulas. Our licensed master plumbers perform the code calculations, draft plumbing schematics, and coordinate with the Roanoke building and health departments to ensure 100% compliance before opening day.
