Grease Trap Cleaning in Chicago for Restaurants and Commercial Kitchens
A grease trap that goes too long between cleanings doesn’t fail quietly. Drains slow down in the dinner rush, odors drift into the dining room, and grease slips out into the building’s sewer line. We do grease trap cleaning in Chicago for restaurants, cafeterias and commercial kitchens that want their traps, interceptors and kitchen lines kept clean, flowing and ready for an inspection.
Our team has more than 20 years of Chicago plumbing experience, professional rodding and hydro jetting equipment, and gives you an honest estimate before any work begins. Call for same-day service, or set up recurring grease trap service around your hours.
What grease trap cleaning involves, and why Chicago kitchens need it
A grease trap, also called a grease interceptor, sits between your kitchen fixtures and the sewer. Wastewater from sinks, dish machines and floor sinks slows down inside the unit. Fats, oils and grease (FOG) float to the top, food solids settle to the bottom, and cleaner water goes on to the sewer. That only works while the trap has room. Once grease and solids fill too much of the tank, grease passes straight through into your plumbing.
Cleaning removes the built-up FOG and sludge, scrapes the walls and baffles, and confirms the inlet and outlet are open. In Chicago, the plumbing code requires a grease interceptor or outside catch basin for kitchen wastes in every commercial kitchen and in multiple dwelling buildings with more than six units. A U.S. EPA fact sheet for food service establishments identifies grease as the most common cause of reported sewer blockages. A regular schedule protects your kitchen, your building and the public sewer downstream.
Signs your grease trap is overdue
- Kitchen sinks, prep sinks or the dish machine drain slowly
- A rancid or sewer-like smell near the trap, floor sinks or dining area
- Water backs up into floor drains when the dish machine empties
- Grease is visible at the trap lid, a cleanout or a nearby floor drain
- The same kitchen line clogs again within weeks of being cleared
- Nobody on staff knows when the trap was last pumped or cleaned
Any one of these usually means the trap is near capacity. Booking service now costs far less than a backup that shuts the kitchen down mid-shift.
How a grease trap visit goes
A commercial kitchen can’t stop for a plumbing visit, so we plan each service around your hours and your equipment. Every visit follows the same five steps, which gives you a consistent result and a clear picture of your trap over time.
1. We schedule around service
Tell us your trap type, where it is and when you operate. We plan the visit before opening, between shifts or after close whenever the job allows.
2. We inspect and measure
We open the trap, check the depth of the grease layer and settled solids, and look at the baffles, lid and gaskets for wear or damage.
3. We remove grease and solids
We pump or remove the floating FOG, settled food solids and gray water, then scrape the walls and baffles so the trap is back to full capacity.
4. We clear the connected lines
If the inlet or outlet line is sluggish, we rod or hydro jet it, so grease that already slipped past the trap doesn’t cause the next backup.
5. We verify and report
We run water through the fixtures to confirm full flow, then explain what we found in plain language you can add to your maintenance records.
Interceptor cleaning and trap pumping
Not every kitchen has the same equipment, and the service changes with the size of the unit. Here’s how the two most common setups compare:
| Feature | Grease trap | Grease interceptor |
|---|---|---|
| Typical location | Under or beside a sink, indoors | In the floor or buried outside the building |
| Size | Smaller, serves one or a few fixtures | Larger, often serves the whole kitchen |
| Cleaning method | Manual removal of grease and solids | Pumping out the full tank |
| Service interval | More often, because capacity is small | Less often, based on kitchen volume |
Pumping empties the whole tank, not just the floating layer, so the unit starts fresh. When you call, tell us the size and location of your interceptor and when it was last serviced. We’ll confirm what the job needs, including access, pump-out and disposal, and give you an estimate before we schedule the work.
What a restaurant grease trap service includes
Grease problems rarely stop at the trap. Our service covers the trap and the kitchen plumbing around it, so you’re not paying for a clean trap that still drains into a clogged line.
Under-sink trap cleaning. Small indoor traps under three-compartment and prep sinks, cleaned out and checked for a tight lid seal.
Interceptor cleaning. Larger in-floor and outdoor units that serve the whole kitchen, with grease and sludge removed and the baffles cleaned.
Kitchen line rodding. Motorized drain cleaning for the sink, dish machine and floor sink lines that feed the trap.
Hydro jetting. High-pressure jetting to scrub hardened grease off pipe walls when rodding alone won’t keep a line open.
Camera inspection. A sewer camera inspection to check the pipe past the trap for grease buildup, sags or damage.
Why scheduled service beats emergency calls
Routine service costs less than emergency calls and keeps your kitchen out of trouble. Regular cleaning helps you:
- Avoid backups during service. A trap with room to work keeps sinks and floor drains flowing through the rush.
- Control odors. Removing decaying grease and food solids gets rid of the source of the smell, and not just the symptom.
- Protect your sewer line. Less grease escaping the trap means fewer clogs in the lateral and the main line.
- Stay inspection-ready. A steady schedule and service notes show that your kitchen manages its grease responsibly.
- Plan your budget. Scheduled maintenance is predictable. Emergency backups aren’t.
How often should you clean? It depends on your menu, cooking volume and trap size. A common rule of thumb is to service the trap before grease and solids fill about a quarter of its depth. Fryer-heavy, high-volume kitchens may need monthly service, while lighter operations can often go longer. We’ll help you set an interval based on what we actually find in your trap.

Grease trap questions
It depends on trap size, menu and cooking volume. Many kitchens clean small under-sink traps every few weeks to monthly and service larger interceptors on a longer schedule. A common guideline is to clean before grease and solids reach about 25% of the trap's depth.
Cleaning usually means removing grease and solids from a smaller indoor trap and scraping the inside. Pumping empties the full contents of a larger interceptor or tank. Many kitchens need both, depending on their equipment.
In many cases, yes. The Chicago plumbing code requires a grease interceptor or an outside catch basin for kitchen wastes in every commercial kitchen, in multiple dwelling buildings with more than six units, and wherever the Department of Water Management requires one.
It depends on the size of the trap or interceptor, how full it is, how easy it is to reach, and whether connected lines need rodding or jetting. We give you an honest estimate before any work begins, with no hidden charges.
We schedule around your operating hours whenever the job allows, including before opening or after close, so service doesn't interrupt your kitchen.
Grease passes through a full trap into your drain and sewer lines, causing slow drains, odors and backups. Escaped grease also adds to blockages in the public sewer.
Yes. We rod or hydro jet the inlet and outlet lines, sink lines and floor sink drains when they're slow or clogged, and a camera inspection can confirm the line is clear.
Yes. Our 24/7 line handles overflowing traps and kitchen backups that can't wait. Call (773) 588-1200 and we'll help you limit the damage while a technician is on the way.
