How Often Should Restaurants in Union County Have Their Grease Traps and Drains Hydro-Jetted?

Every kitchen on the St. Georges Ave and Route 1&9 corridor has a grease story. The good ones are maintenance calendars; the bad ones are Friday-night backups with the health inspector's phone number in the file. The difference between the two is usually a single decision: jetting on a schedule versus jetting on a crisis.

What Grease Actually Does Inside the Line

Emulsified by hot water and detergent, grease leaves the kitchen as a liquid and renatures on the cool pipe wall a few meters out, depositing layer on layer. The ring narrows the channel, snags solids, and hardens into a deposit that hot water will not remelt; mature deposits need mechanical force, which is why the EPA identifies fats, oils and grease from restaurants, homes and industry as the nation's most common cause of reported sewer blockages. (Source language: EPA on FOG blockages.) A trap that gets pumped on schedule still feeds a line that never gets scoured, and the line is where the failure happens.

Frequency: A Starting Matrix

The matrix is a starting point, not a verdict: the first camera scope reads the actual grease depth in your lines, and the interval gets set from evidence rather than a brochure. Kitchens that stretch the interval to save money pay for it in one mid-service emergency, at emergency rates, with the dining room full.

Union County Reality: Inspectors and Fatbergs

Union County health inspections ask where grease goes and whether the records show it; scope documentation and service logs answer that question in a folder. Meanwhile, downstream, municipal systems across the country pull grease-concreted masses ("fatbergs") from their mains at real cost, and enforcement increasingly traces them to the kitchens that fed them. A documented jetting program is cheaper than any of that, and it is the only version of the story where the kitchen controls the calendar.

Signs the Schedule Is Already Too Slow

• Floor drains and prep sinks that gurgle between services.
• Trap pump-outs filling faster than last quarter.
• A sewer odor in the dish pit on humid days.
• Camera footage showing a yellow-walled ring despite scheduled cleaning.

How the Program Works

Off-hours windows, pre-opening or post-close, so service never competes with tickets. Lines get jetted to bare wall, traps serviced, and a camera pass documents the condition each cycle; the manager gets the footage and the next recommended interval in writing. That is the whole machine, and it is why our commercial clients on the corridor stop having dinner-rush emergencies. High-pressure specifics live on the jetting page, and multi-family landlords need a different cadence entirely, covered in the landlord guide.
