Signs of grease and sludge buildup
- Prep and dish sinks drain slowly even after the trap has been cleaned
- Clogs return within weeks or months after clearing
- Rancid or sour odors from sinks or kitchen floor drains
- Kitchen floor drains back up during heavy dishwashing
- Gurgling from kitchen drains during busy periods
- Grease visible at cleanouts, or a grease trap or interceptor that fills faster than expected
What fats, oils and grease do to a pipe
Fats, oils and grease, often called FOG, do not stay liquid. As they cool, they separate and cling to the pipe wall. Each layer catches more debris. Soap can react with fats to form a hard, waxy material that sticks even more firmly. Starchy foods like rice and pasta add bulk. The result is a pipe that looks normal from the outside but has a much smaller opening inside.
Hot water and detergent move grease farther down the line, but they do not remove it. It hardens again where the pipe is cooler, often under the floor, past the interceptor or in the building sewer.
Why snaking alone is often not enough
A cable is good at punching through a blockage, but in a grease-lined pipe it leaves a ring of buildup behind. The drain works for a while, then closes again. For heavy grease, hydro jetting is usually the better approach. High-pressure water scours the pipe wall and breaks the buildup into pieces that can be removed or captured where access allows, restoring much more of the original diameter.
Before jetting, we consider the pipe material and condition. Older or damaged pipes may need a gentler approach, and a camera inspection can help us decide.
Grease traps, interceptors and the lines around them
Food service businesses typically have a grease trap or a grease interceptor. Both catch much of the grease before it reaches the sewer, but the lines leading to and from them still collect buildup, and a neglected trap lets grease pass straight through. We clear kitchen branch lines, floor drains and the piping connected to grease control equipment.
Pumping out an interceptor is usually handled by a grease hauling company. We focus on the drain lines and can coordinate timing with your hauler so the lines and the interceptor are serviced together. For a broader look at restaurant plumbing, see commercial drain cleaning.
Kitchen habits that reduce grease buildup
- Collect fryer oil and cooking grease for recycling or proper disposal, never down a drain.
- Dry-wipe pans and scrape plates into the trash before they reach the dish sink.
- Keep strainers in every prep and dish sink and empty them often.
- Do not pour grease or food waste into mop sinks or floor drains.
- Keep up with trap or interceptor service so it does not overflow into the line.

Grease and FOG rules in Long Beach
Food service establishments in Long Beach are generally subject to local fats, oils and grease (FOG) requirements covering grease control equipment and maintenance practices. The details can change, so confirm your current requirements with the City of Long Beach or Long Beach Utilities.
Clean kitchen lines help you stay ahead of those obligations and reduce the grease your building sends to the public sewer, where buildup is a common cause of sewer overflows. Keeping a simple log of when lines were cleaned and the interceptor was serviced makes it easier to answer questions and to spot when buildup is returning faster than usual.
