Professional grease trap cleaning involves comprehensive multi-step process ensuring trap functions properly and meets health code requirements.
Step 1 – Complete Pumping: Remove all contents including liquid grease (floating on surface), wastewater (middle layer), and settled solids (bottom accumulation). Professional vacuum truck pumps all material ensuring trap completely empty for thorough cleaning. Improper pumping leaving material reduces trap capacity and violates health codes.
Step 2 – Thorough Scraping: After pumping, hardened grease adheres to trap walls, baffles, and bottom requiring manual scraping. This labor-intensive step removes material pumping cannot extract. Skipping scraping leaves deposits that reduce trap effectiveness and violate health codes requiring “complete cleaning.” Professional service includes thorough scraping ensuring truly clean trap.
Step 3 – Inlet/Outlet Line Jetting: Grease accumulates in inlet line (from kitchen to trap) and outlet line (from trap to main sewer) creating restrictions and backup problems. High-pressure hydro jetting removes all grease from these lines preventing problems between trap cleanings. Critical step many basic services skip.
Step 4 – Documentation: Complete written records documenting service date, trap condition, materials removed, technician signature. Essential for health inspections proving compliance with cleaning frequency requirements.
Pumping Alone: Basic grease trap service involves only pumping liquid contents from trap using vacuum truck. Pumping removes floating grease layer and wastewater but leaves hardened grease on walls, does not address inlet/outlet line buildup, provides temporary relief but incomplete service. Pumping-only service costs less initially but provides inadequate results failing to maintain trap properly or satisfy health code “complete cleaning” requirements.
Complete Service with Jetting: Professional service combines pumping with scraping and hydro jetting. Removes ALL grease including hardened deposits on trap walls, clears inlet and outlet lines preventing backup problems, maintains trap at full design capacity, satisfies health code complete cleaning requirements. Costs more initially but provides proper maintenance preventing violations, backups, and operational problems. Superior long-term value protecting business operations and regulatory compliance.
Why Jetting Matters: Grease buildup in inlet and outlet lines creates restriction causing slow draining, backup into kitchen during service, foul odors from trapped grease, trap appearing full immediately after pumping (actually line restriction). Hydro jetting removes these restrictions maintaining proper flow. Essential for restaurants experiencing recurring drain problems despite regular trap pumping—lines need jetting not just trap pumping.
Local health departments mandate regular grease trap cleaning for food service operations because grease discharge into municipal sewers causes serious problems: grease solidifies in sewer lines creating blockages, grease buildup requires expensive municipal sewer maintenance, grease overflows create environmental hazards and public health concerns. Health codes require grease traps to contain grease preventing sewer discharge—but traps only work when properly maintained through regular cleaning.
Typical requirements mandate cleaning when trap reaches 25% full (measured by grease layer thickness plus settled solids depth). For most restaurants, this occurs monthly or quarterly depending on kitchen volume and grease generation. Skipping required cleanings violates health codes resulting in citations, fines, mandatory cleaning orders, potential license suspension or revocation for repeated violations, business closure orders in severe cases. Regular professional cleaning ensures compliance protecting business license and operations.

Maintain health code compliance and prevent expensive violations with professional grease trap service.
Service begins with complete trap pumping using professional vacuum truck. We remove trap lid (typically in parking lot, alley, or kitchen floor), inspect trap contents documenting fullness level, pump all liquid grease layer (floating on top—primary concern), pump all wastewater (middle section), pump all settled solids (bottom accumulation—often overlooked). Complete pumping requires appropriate equipment and expertise. Inadequate pumping leaves material reducing trap capacity and violating health codes. We ensure trap completely empty providing foundation for thorough cleaning. Pumped materials transported to licensed disposal facility meeting environmental regulations—proper disposal protects you from liability.
After pumping, hardened grease adheres to trap walls, baffles, and bottom. This material requires manual scraping for removal—pumping alone cannot extract hardened deposits. Our technicians enter trap (when size permits and safety allows) or use specialized tools performing thorough scraping of all surfaces, removing hardened grease from walls and baffles, cleaning trap bottom and corners where material accumulates, ensuring baffles move freely and function properly. This labor-intensive step separates professional service from basic pumping. Skipping scraping violates health code “complete cleaning” requirements leaving trap partially full of hardened material. Thorough scraping ensures truly clean trap operating at full design capacity.
With trap clean, we address inlet and outlet lines using high-pressure hydro jetting.
Inlet Line (Kitchen to Trap): Remove grease buildup from kitchen drain line leading to trap. This line carries all kitchen grease water and accumulates grease coating pipe walls. Jetting removes deposits ensuring proper flow into trap.
Outlet Line (Trap to Main Sewer): Clean line carrying wastewater from trap to building main sewer. Grease escaping trap (normal in operation) accumulates in this line. Jetting removes buildup preventing restriction and backup problems.
Line jetting prevents common situation where restaurant experiences slow draining or backups immediately after trap pumping—problem is line buildup not trap itself. High-pressure water (3,000-4,000 PSI) removes all grease from pipe walls restoring proper flow. This critical step maintains functionality between trap cleanings preventing operational disruptions.
Complete service includes comprehensive documentation for health code compliance. We provide detailed service records including service date and time, trap identification and location, contents removed (gallons/pounds), condition notes and recommendations, technician name and signature, company license information. This documentation proves compliance with required cleaning frequency when health inspector reviews records. Without proper documentation, you cannot prove compliance even if trap was cleaned—inadequate records result in violations.
We also provide compliance tags or stickers (if required locally) posting at trap location showing last service date and next required service date. Many jurisdictions require visible compliance indicators. Our complete documentation protects your business ensuring you can demonstrate proper maintenance and regulatory compliance during health inspections.
Michigan health departments regulate grease trap maintenance through food service sanitation codes. Key requirements include grease traps required for all food service operations discharging fats, oils, or grease (FOG) into sewer systems, traps must be properly sized for kitchen volume (based on fixture units, seating capacity, or kitchen square footage), cleaning required when trap reaches 25% full (measured by combined grease layer thickness and settled solids depth), complete cleaning required removing ALL contents including hardened material, documentation required proving cleaning frequency compliance.
Wayne County and Monroe County health departments actively enforce these requirements during routine inspections and complaint investigations. Violations result in citations requiring immediate correction, fines ranging from hundreds to thousands of dollars depending on severity, mandatory cleaning orders with follow-up inspection, potential license suspension for repeated or serious violations, business closure orders in extreme cases. Maintaining compliance protects your business license, operations, and reputation avoiding these serious consequences.
Monthly Service: Required for high-volume operations including full-service restaurants with heavy frying, high-capacity commercial kitchens, facilities serving 100+ meals daily, operations with previous violation history or compliance concerns. Monthly service prevents trap from reaching 25% full threshold maintaining continuous compliance. Recommended for operations unable to risk violations or disruptions.
Quarterly Service: Sufficient for moderate-use operations including smaller restaurants with moderate cooking volumes, cafeterias or institutional kitchens, food service with limited frying operations, properly sized traps in facilities with reasonable volumes. Quarterly service satisfies typical health code requirements while balancing cost with compliance. Most common schedule for restaurant operations.
Determining Your Frequency: Required cleaning frequency depends on trap size (larger traps hold more material allowing longer intervals), kitchen volume (higher volume generates more grease requiring more frequent cleaning), cooking methods (heavy frying generates more grease than grilling or baking), previous compliance history (violation history may require increased frequency). Health inspector may mandate specific frequency based on your operation—compliance is not optional. When unsure, monthly service provides maximum protection and compliance certainty.
⚠️ Violation Consequences: Grease trap violations are serious matters. First violation typically results in written warning with correction deadline. Subsequent violations result in fines ($500-$2,500 typical), mandatory immediate cleaning with follow-up inspection, potential license suspension for repeated violations, business closure orders for severe or continuing violations. These consequences far exceed cleaning costs—preventive maintenance is smart business investment protecting operations.
Health inspectors review grease trap maintenance records during routine inspections. Required documentation includes service dates showing cleaning frequency meets requirements, service provider name and contact information, detailed service descriptions (pumped, scraped, jetted), volume or weight of material removed, technician signatures, company license numbers. Inadequate documentation results in violations even if trap was properly cleaned—burden of proof is on the business to demonstrate compliance.
We provide comprehensive documentation satisfying all health department requirements. Keep service records for minimum 2-3 years (check local requirements). Digital copies provide backup in case physical records lost. Our maintenance contract customers receive automatic documentation with electronic backup ensuring permanent compliance records. Organized documentation during inspections demonstrates professionalism and compliance commitment often resulting in favorable inspector relationships and minimal scrutiny.

Several factors determine appropriate cleaning frequency for your operation:
Kitchen Volume: Higher meal counts and covers generate more grease requiring more frequent cleaning. Track fullness level after first few cleanings establishing pattern for your operation.
Cooking Methods: Heavy frying generates significantly more grease than grilling, baking, or steaming. Fryer-heavy operations need more frequent service.
Trap Size: Properly sized traps (designed for your kitchen’s fixture units) allow longer intervals. Undersized traps fill quickly requiring monthly service regardless of volume.
Menu Characteristics: Grease-heavy menus (fried foods, fatty meats, heavy oil use) generate more FOG requiring increased frequency. Leaner menus allow longer intervals.
Staff Practices: Proper kitchen practices (scraping plates before washing, disposing grease in containers not sinks, using drain screens) reduce trap loads. Poor practices accelerate filling.
Previous History: Violation history or health inspector concerns may mandate increased frequency regardless of current fullness. Better to exceed requirements than risk additional violations.
When establishing schedule, monitor trap fullness at each service. If approaching or exceeding 25% full at scheduled interval, increase frequency. Better to clean more often than necessary than to risk violations or operational problems. We help customers determine optimal frequency based on observed patterns and operational characteristics.
Kitchen sinks and floor drains draining slower than normal indicate trap nearing capacity or line restriction from grease buildup. Water pooling in sinks during busy service periods. Multiple fixtures draining slowly simultaneously. Progressive worsening over days or weeks. Immediate service required before complete backup occurs.
Water and grease backing up into kitchen sinks, floor drains, or equipment drains during dishwashing or heavy use indicates trap at capacity or outlet line blocked. Raw sewage may appear. Immediate operational disruption forcing kitchen closure or limited operations. Emergency situation requiring immediate professional service preventing health violations and revenue loss.
Strong unpleasant odors emanating from kitchen drains, trap area, or dining spaces indicate decomposing grease and organic material in trap. Smells worsen in warm weather or during high-volume service. Customer complaints about odors. Grease decomposition creates hydrogen sulfide (rotten egg smell). Cleaning eliminates odor source improving customer experience.
Health inspector finding violations during routine inspection including trap exceeds 25% full threshold, inadequate cleaning frequency for operation volume, missing or inadequate documentation, visible grease discharge in floor drains or manholes. Violation notices require immediate correction with follow-up inspection. Professional service with complete documentation resolves violations preventing escalated consequences.
⚠️ Don’t Wait for Problems: These warning signs indicate existing problems requiring immediate attention. Professional restaurant operators schedule preventive maintenance on regular calendar preventing these issues rather than reacting to problems. Monthly or quarterly contract service costs far less than emergency calls, violations, and operational disruptions reactive approach creates.
