Dos Donts Grease Traps

Most cities and municipalities today require the use of a grease trap or grease interceptor in order to separate fats, oil and grease from waste water. The grease trap has a very important function. Without it, grease, fats and oil will mix with waste water system and this can lead to a lot of problems. In order to keep the grease trap working and to avoid blocked drains, regular maintenance is a must.

Grease traps come in various sizes and it is important that you choose one which is appropriate for your needs. You can determine the perfect size by the gallons of water which flows out of your establishment. There is also a need to measure the sink where the grease strap will be attached to. Large grease traps may require professional maintenance but smaller ones can be cleaned easily.

Refrain from pouring hot water down the sink. There is a notion that this will help maintain the grease strap and the drain but this will only cause more harm than good. This will flush the grease through the grease strap and into the sewage system. When leaning the grease trap, do not use soap, strong cleaning detergents and acids. Again, this will loosen the grease and flush it into the sewage system and this can result to blocked drains.

Do not forget to clean the grease trap regularly. Grease must be scooped out at least once a week and the entire grease trap must be cleaned at least once every month. However, if grease accumulates faster, you might need to clean the grease trap at least twice a month. It is vital that you follow the manufacturer’s directions for cleaning and if you feel that you might not be up to the task, you should hire a professional for a thorough cleaning.

Never discard your cleaning records. Every time an employee or a professional cleans your grease trap, make sure that you keep a record of it. Aside from the time, you should also keep a record of the amount of grease removed, the location and the disposal method used. There should be a thorough record of the condition of the grease trap and all its parts. In some places, this is a requirement by regulatory agencies. Even if it is not required, it is still a good idea to keep records for your reference.

The grease trap is an integral part of any restaurant or food business. Without it, there will be several problems with the sewage system and blocked drains are just one of them. To avoid problems, you must choose the best type of grease trap for your needs. After it is installed, proper maintenance must be done regularly. If you do not commit yourself to cleaning, the grease may be flushed to the sewage system.


We may not pay much attention to our grease traps but it is time to change this now. You surely would not want to spend thousands overhauling your entire sewage system or having repairs done. This will not only cost you money, it can also mean a disruption of business.
