The process of installing a grease trap involves determining the size of the grease trap, deciding on the location for the grease trap and connecting the grease trap. Install the trap in an easily accessible location. The trap prevents clogging of drainage systems and sewers by trapping wax, oils and fats.
The size of a grease trap depends upon the amount of wastewater that goes through the drainage system. Restaurants that wash dishes frequently need large grease traps. You can install a grease trap under the sink or outside the house. For a home with many sinks, placing the trap outside the house may be a good option. Connect all drainage pipes to one pipe, and fit the pipe to the grease trap.
Installation of a grease trap varies with the model, so install the trap, which has three connections, according to the manufacturer's recommendations. Connect the first connection to the holding tank vent, the second connection (located on the left side of the grease trap) to the source of wastewater and the third connection (located on the lower right of the device) to the pipe that links with the sewage system. Install a clean out tee before doing the first connection to clear out any debris that may enter the device.
Ensure that the sink traps all solid wastes. Once you have washed greasy items, pour hot water into the drainage to ease the flow of grease.
