3 Steps for Grease Trap Installation

Grease trap installation does not require the help of a professional plumber, unless one lacks the basic skills needed for this plumbing job. Nonetheless, a do-it-yourself grease trap installation can be a cost effective way to preventing grease from clogging the drainage and the sewer system. A grease trap is a simple device that is designed to trap oils, fats and wax in a container to prevent them from reaching the sewers and the drainage systems. Law in most states, especially in restaurants and food preparation businesses, mandates the installation of a grease trap. A grease trap should be installed in a location where it is accessible in order to allow the owner to clean it occasionally. Here are three steps to follow in grease trap installation.

Step 1 – Determine the Size of the Grease Trap

The size of a grease trap varies from one model to another. The size needed for a home or a business depends on the quantity of wastewater that usually passes on the drainage pipes. For restaurants that wash greasy dishes regularly, a grease trap with a capacity of 40 KG of grease is best. For residential use, a grease trap with a smaller capacity is okay. If one wants to have a grease trap that will need cleaning for a longer period of time, a larger grease trap is a good option.

Step 2 – Determine Where to Install the Grease Trap

The best location for grease trap installation is under the sink. However, it can also be installed outside of the house. External grease trap installation is best for homes with several sinks. The drainage pipes can all be connected to the one common pipe and fitted to the grease trap.

Step 3 – Connect the Grease Trap

A grease pipe’s installation will vary from one model to another. Read the manufacturer’s instructions to make sure a proper installation is done. Normally, there are three connections on the device. One connection is to be connected to the holding tank vent. This vent is purposely for flow control. Before connecting the device to the vent, plumber’s recommend installing a clean out tee first. This will help clean out any debris that comes into the device. The second connection is designed to be connected to the sink or the source of wastewater. This connection is usually found on the left side of the device. Connect this after the vent connection. Lastly, connect the last connection to the pipe that leads to the sewage system. This pipe is usually found on the lower right of the grease trap.

Tips and Reminders

Do not allow solid waste to go down the drain and into the grease trap. Make sure that the sink captures every solid matter that is washed down the sink. After washing greasy material down the drain, run hot water on the sink to help with the flow of grease.

Installing a grease trap is a preventive system, and is a better way in keeping the pipes oil-free for a longer period of time than chemical decloggers that works by melting hardened grease that thickened inside the pipes with toxic chemicals.
