Grease Trap Cleaning in Enid, OK

What is a grease trap, and what does it do?

A grease trap is a small tank fitted into the drain line from a commercial kitchen. Wastewater from sinks and dishwashing flows through it slowly enough for fats, oils, and grease to float to the top, while heavier food solids settle to the bottom.

That separation is the whole job of the trap. Grease that reaches a drain line cools, hardens, and coats the inside of the pipe. But a trap only holds so much — as grease and solids build up inside it, there is less room for separation, and more grease passes through to the lines beyond.

Most commercial kitchens have one of two setups: a smaller trap under or near a sink, or a larger interceptor outside or in the ground. Both do the same job at different sizes, and both need cleaning.

How do you know a grease trap needs cleaning?

• Kitchen sinks drain slowly, even though the sink itself is clear of food and debris.
• A floor drain in the kitchen backs up, especially during a busy service when a lot of water is going down at once.
• A strong, stale grease odor hangs around the sink area or the floor drain and does not go away after the kitchen is cleaned.
• Grease is visible in a drain, a floor sink, or water standing in a sink.

One slow sink on its own can be a single drain problem. When several kitchen drains are slow at the same time, or a floor drain backs up, the trap is a likely place to look — and it is the detail to describe on the call.

This page is for commercial grease traps. A slow kitchen sink in a home is a different job, covered on the Kitchen Drain Cleaning page.

What is the difference between a grease trap and a grease interceptor?

	Grease trap	Grease interceptor
Where it sits	Inside, under or near a kitchen sink	Outside or in the ground, on the main kitchen drain line
Size	Smaller, serves one sink or a small kitchen	Larger, serves a whole kitchen or several kitchen fixtures
Who has one	Small cafes, small kitchens, single food stations	Restaurants, larger kitchens, food service operations with heavy grease output
Cleaning	Pumped out and scraped clean	Pumped out with larger equipment, baffles checked

Both need the same thing: the grease and solids removed, the inside cleaned, and the baffles — the walls inside the unit that slow the water down — checked. An interceptor is not a different service on this site. It is the larger version of the same job, covered on this page.

What does grease trap cleaning involve?

1. Call — say what kind of kitchen it is, where the trap sits, and what the drains are doing. Slow drains during service, odors, or a backup are the details that matter.
2. Open the trap — the lid is lifted so the contents can be seen and the level of grease and solids checked.
3. Pump out the contents — the grease layer, the settled solids, and the wastewater in the trap are pumped out.
4. Clean the inside — the walls and the baffles are scraped and washed down, so the trap starts clean rather than partly full.
5. Check the baffles and the flow — the baffles are checked for damage, and water is run to confirm the kitchen drains flow again.

Keep the record of each cleaning. If anyone asks when the trap was last cleaned, the record answers it.

How often does a grease trap need cleaning?

There is no fixed schedule that fits every kitchen — it depends on how much grease the kitchen produces, how large the trap is, and how many hours a day the kitchen runs. A busy restaurant kitchen fills a trap far faster than a small cafe.

One commonly cited guide is the 25% rule: when grease and solids together take up about a quarter of the trap’s depth, it needs service. That is a guide for judging the trap in front of you, not a fixed calendar date — have the trap checked on a regular basis and cleaned when the level shows it is due, rather than waiting for a backup to decide.

What happens if a grease trap is left too long?

A trap that is left too long stops separating grease. Grease passes through into the drain lines, where it cools and hardens on the pipe walls. Kitchen drains slow down first, then a floor drain can back up during service, when the most water is going down at once.

Grease in the lines beyond the trap also builds up over time. Hydro jetting scours the inside of the pipe and removes the grease coating, where a cable alone only opens a hole through it.

If grease is already backing up through a floor drain, see the Emergency Drain Cleaning page first and stop running water in the kitchen.

What should you not do with a full grease trap?

Do not pour hot water down the drain to “melt the grease through.” Hot water moves grease a little further down the line, where it cools and hardens again — often in a worse spot. Do not pour chemical drain cleaner into a kitchen drain that runs through a grease trap. It does not remove the grease already sitting in the trap, and it can damage the trap. Do not keep running the dish machine or the sinks to “flush it through” when a floor drain is already backing up. Do not ignore a slow kitchen drain because service is busy. A slow drain is the early warning; a backup during service is the problem it was warning about.

What can cleaning not fix?

Cleaning a grease trap removes grease and solids and restores flow. It does not fix a trap that is cracked or broken, a baffle that has fallen apart, or a drain line that has collapsed. Those are different problems from a full trap, and cleaning alone will not put them right.

In Enid

Enid has older buildings near downtown, around Broadway Tower, and the drain lines in those buildings are often older pipe. In an older building, the line a grease trap drains into may already be narrowed by mineral scale, so grease that passes a full trap has less room to get through. Mature trees are a common sight in Enid, and roots can find their way into the drain lines beyond a trap, catching grease and solids until the flow narrows. None of this changes what a grease trap is or how it is cleaned — it is why a trap in an older building is worth keeping on schedule.
