Grease Trap Installation


A grease trap is a device used in restaurants, catering businesses, cafeterias, and any other commercial cooking facility. Its main purpose is to keep oils, fats, waxes, and other debris from falling into the city’s sanitary sewer systems. This prevents blockages in the system that could lead to an overflow. It is therefore important to install a grease trap in an accessible place so that you can clean it with ease. For optimal grease trap installation, follow the steps below.

1. Determine Size

Grease traps are available in different sizes, and the size you choose will depend on your particular needs. The size required for business or home use depends on the quantity of the wastewater that passes through the drainpipes. Commercial cooking facilities such as restaurants need a grease trap that can handle 40 KG of grease. That said, you should also check with your city to see if its health codes require you to use a trap with a different grease capacity. For residential use, you should install a grease trap with a smaller capacity than one you would use in a restaurant. Keep in mind that the larger the trap is, the longer it can go between cleanings.

2. Determine the Installation Location

Figure out where you want to install your grease trap. It is usually best to install it under the sink. For homes with several sinks, however, it may be best to install it outside of the house. Make sure that the location you choose will allow you to connect all the drainpipes to the grease trap and enable you to clean it easily.

3. Connect the Grease Trap

When it comes to installing grease traps, the process varies depending on the model you’re using. Therefore, you should read the instruction manual to ensure a smooth installation.

Generally, the device will come with three connections, the first of which is joined to the tank vent. The main purpose of the vent is to control the flow rate. It is advisable to clean out the tee before you connect your grease trap to the vent, as this will get rid of any debris in the device.

The second connection links to the source of wastewater or the sink itself, and is attached after the vent connection. The last connection is to the pipe, which goes into the sewage system. This pipe can be found on the lower right side of the device.

Whether you chose to tackle this job yourself or call in a pro, make sure you maintain the grease trap to keep the water supply clean and properly flowing.
