Buying advice

When choosing a commercial grease trap, first check local plumbing codes for certified standards (like PDI-G101 or ASME A112.14.3). Ensure you size the trap correctly based on your sink's gallon capacity and drainage flow rate (GPM). Consider plastic or polyethylene models if you want to avoid rust entirely, or heavy-duty epoxy-coated steel models if your kitchen requires extreme physical durability.
