Grease trap installation process

When having a grease trap installed always ensure to use a reputable company with knowledge in grease trap installations. This can save you time and money down the track from faulty or improper installation. When it comes to installing a grease trap it is broken down into three stages.

Determining the size needed

Every grease trap will have different sizes, whether its different models or different brands. The size of the grease trap you will need will be determined by the amount or quantity of wastewater that passes through the drainage pipes.

As a point of reference, a restaurant washes greasy/dirty dishes quite frequently so using a 40kg grease trap or bigger should be more than adequate. The larger the grease trap the longer you have between cleans (The longer between cleans typically takes longer to clean).

Where to install the grease trap

Typically the best location to install a grease trap is under a sink.

Grease traps can also be installed outside but this is only advised when places have multiple sinks. The reason for this is so that all of the sinks can funnel into one larger grease trap saving on saving on having multiple grease traps.

Connection of the grease trap

Generally, there are 3 connections on a grease trap.

  • The first will be to the holding tank vent. This vent is to allow the flow of the wastewater.
  • The second will be connected to the source of the wastewater such as the sink.
  • The third is the pipe that connects the grease trap to the sewage system.

What can go into a grease trap

It is strongly advised to not allow any solids to get into your grease trap. Ensure that your drains are fitted with gauze or drain catchment device that will pick up all of the solids prior to going down the drain.

You can run hot water down the drain after you have removed the solids to help the grease to make its way into the grease trap.
