Grease traps work by capturing absolutely everything that goes through the drain ( this includes water, grease
and other solids and liquid matter )
Traps have two separation basins, the first basin fills with all the
matter that is drained from the sink, the matter then cools. when grease is cooled it congeals, becoming a solid.
The grease trap needs to be cleaned and serviced with a regular frequency to prevent the solids from building up and the trap
to stop functioning properly. When the trap stops functioning properly the grease will bypass the trap and go directly into the sewer. This
is illegal and can lead to Muncipal fines and costly clean up expenses.
