SECTION 2: QUESTION AND ANSWER
Grease hardens on pipe walls and narrows the drain, so water and waste pass through a smaller opening and blockages form more easily. Clearing a path through the grease often leaves a coating behind, which catches more grease later, so the same drain can clog again even after it was cleared. Describing whether the same drain has clogged before helps when you call.
SECTION 3: SIGNS OF A GREASE CLOG
These signs point to a buildup problem, not a single object blocking the drain once. A grease buildup narrows the pipe from the inside, so the drain can look clear for a while and then slow down again.
HOW GREASE CLOGS A DRAIN
Grease means fats, oils, and grease, called FOG for short. FOG goes down a drain as a liquid when it is hot, then cools and hardens on the inside wall of the pipe. Over time, layer after layer of hardened grease narrows the pipe, so less and less water can pass through. Soap and small bits of food waste can stick to the grease layer and narrow the pipe further. That is why a grease clog often builds up slowly, and why it can keep coming back even after the drain has been opened up once.
HOW A GREASE CLOG IS CLEARED
01
Describe whether the drain slows gradually, clogs again after clearing, or narrows over time, and whether the same drain has clogged before.
02
The drain is checked, in general terms, to find whether grease buildup is the likely cause and how far the narrowing reaches.
03
The grease buildup is cleared from the drain. Method pointers only: see Drain Snaking / Augering and Hydro Jetting for the method explanations.

SECTION 5: WHY GREASE CLOGS RECUR
A grease clog recurs because the pipe wall is still coated after a simple opening-up. A cable tool that punches a hole through a blockage can restore flow without removing the grease coating, see Drain Snaking / Augering for the method explanation. The coating that is left behind can catch new grease and narrow the pipe again. Jetting, by contrast, scours the full pipe wall rather than just opening a path, see Hydro Jetting for the full method comparison. Which method fits a grease clog depends on the pipe and the buildup, so describe the recurrence pattern when you call.
SECTION 6: HOMES AND BUSINESS PREMISES
Grease buildup can affect a drain in a home and a drain in a business premises in the same basic way: grease cools, hardens, and narrows the pipe over time. The difference is usually how much grease goes down the drain and how often the drain is used, not the buildup itself. This page covers the grease cause in general terms for homes and businesses in Pasadena. For a business drain problem in general, see Commercial Drain Cleaning. No specific business type is named here, because no specific type is confirmed for publication.

SECTION 10: TOOLS AND EQUIPMENT
A grease clog is cleared with standard drain tools, chosen for the buildup rather than for a single object. A cable tool can open a path through a blockage, while jetting can scour the pipe wall, see Drain Snaking / Augering and Hydro Jetting for the method explanations. A camera may be used as a closer look if a grease problem keeps coming back, see Video Camera Drain Inspection. No tool brand, model, or specification is claimed here. If a drain problem is tied to a particular fixture, see Kitchen Drain Cleaning.
SECTION 11: BENEFITS OF CLEARING A GREASE CLOG
SECTION 12: GREASE HABITS THAT HELP
Let cooking grease cool and put it in the trash instead of pouring it down a drain, because liquid grease hardens inside the pipe as it cools. Wipe greasy pans with a paper towel before washing them, so less grease reaches the drain. Avoid pouring large amounts of oil down a drain at once, even with hot water running, because the grease still cools and hardens further down the pipe. These habits lower the amount of grease reaching the drain; they do not remove grease that has already hardened in the pipe.

FREQUENTLY ASKED QUESTIONS
A drain keeps clogging with grease because hardened grease coats the inside of the pipe and narrows it over time. Clearing a path through the grease can restore flow without removing that coating, so new grease can stick to it and narrow the pipe again. Removing the coating gives the drain a better chance of staying clear.
Hot water can melt grease near the top of a drain, but the grease cools and hardens again further down the pipe, so hot water alone does not remove a grease buildup. That is why a grease drain can seem clear for a while and then slow down again. If the drain keeps clogging, describe the pattern when you call.
Snaking uses a cable tool to open a path through a blockage, but it can leave a grease coating on the pipe wall. Jetting uses water to scour the full pipe wall, which can remove that coating. The comparison belongs to the jetting page, and which method fits depends on the pipe, so describe the pattern when you call.
Let cooking grease cool and put it in the trash instead of pouring it down a drain, and wipe greasy pans before washing them, so less grease reaches the pipe.
