In the hustle and heat of a commercial kitchen, it’s easy to overlook what’s happening below the surface—literally. Beneath your sinks and floors, your grease trap is working hard to keep fats, oils, and grease (FOG) out of your plumbing system. It’s the heart of your kitchen’s grease containment strategy, preventing expensive backups, foul odors, and code violations.

However, when grease traps are ignored, they quickly become a source of frustration—and risk. Grease builds up, pipes clog, and waste backs into your kitchen. The result? Health hazards, business interruptions, and major repair bills.

What Is a Grease Trap and Why Is It So Important?

A grease trap (also known as a grease interceptor) is a plumbing device designed to capture FOG before it enters the sewer system. Installed in the waste water drainage line, the trap slows down the flow of water so grease can cool, solidify, and separate from other waste.

Without a functioning grease trap:

• Grease hardens in pipes, causing blockages
• Foul odors seep into your kitchen and dining areas
• Local plumbing systems become overwhelmed
• Your kitchen could be fined or shut down for violations

Regular grease trap cleaning is the only way to prevent these issues.

The Dangers of Ignoring Grease Trap Maintenance

When a grease trap isn't cleaned regularly, the FOG it’s designed to trap begins to overflow or bypass the trap altogether. Here’s what that means:

• Plumbing damage: Grease-laden water clogs pipes and can damage city sewers
• Backflow: Raw waste can back up into your sinks and drains
• Health violations: Overflowing grease traps are a red flag for inspectors
• Foul odors: The smell of rotting food and grease can drive away customers
• Environmental fines: Many municipalities issue citations for improper grease disposal

In short: skipping grease trap cleaning can cost you your business’s reputation—and a lot of money.

What Happens During a Grease Trap Cleaning?

Professional grease trap cleaners follow a detailed process to ensure complete removal of FOG:

1. Inspection: Evaluate the trap’s condition and capacity
2. Pumping: Use vacuum equipment to remove accumulated grease and solids
3. Scraping and washing: Manually scrape walls, baffles, and parts for deeper cleaning
4. Line flushing: Clean connected lines to prevent blockages
5. Documentation: Provide service records for compliance with local regulations

A certified company may also provide recommendations for future cleanings or upgrades.

How Often Should You Clean a Grease Trap?

Cleaning frequency depends on trap size, kitchen output, and local code, but here's a general guide:

If your trap is 25% full of grease, it’s time for service—this is the standard "25% Rule" many cities enforce.
