If you own or operate a commercial kitchen, you’re more than likely already acquainted with that undercover kitchen saviour, the grease trap. These boxes, hidden somewhere between the main sink and the city sewer line, have one role: to catch fat, oil and grease and prevent it from clogging drains. Kitchen grease is the number one cause of blockages in pipes and sewer lines, so pre-emptive action when you have a business to run is a must. Grease traps prevent clogs and their potential consequences, like sewage backups and flooding. Keeping them well maintained will ensure that all continues to flow smoothly.
