How many fixtures may be installed or connected to a single grease trap?

The correct answer is that up to four fixtures may be installed or connected to a single grease trap. This standard is based on the design and capacity of the grease trap, which is intended to capture fats, oils, and grease from wastewater before it enters the sewer system.

Each grease trap has a specific flow rate and holding capacity, which can typically accommodate a certain number of fixtures depending on usage and the nature of the waste produced by those fixtures. In most cases, local plumbing codes or regulations will specify the maximum number of connected fixtures to ensure the grease trap functions efficiently and effectively.

Connecting too many fixtures can lead to overloading, which diminishes the trap's ability to separate grease from wastewater, resulting in possible backups, odors, and non-compliance with health regulations. Therefore, understanding the limits imposed for grease traps is crucial for proper sanitation and functionality in commercial kitchens and facilities where grease is prevalent.
