When is it acceptable to install grease traps?

The installation of grease traps is specifically intended for situations where a grease interceptor cannot be accommodated. Grease traps serve to prevent grease, fats, and oils from entering the wastewater system, thereby protecting the plumbing and treatment facilities from grease buildup. These devices are commonly used in commercial kitchens where food preparation occurs, and where there is a risk of excessive grease entering the drainage system.

In circumstances where the physical space is insufficient to install a larger grease interceptor, or when the application does not allow for the use of an interceptor due to layout constraints, a grease trap becomes a necessary solution. This ensures compliance with plumbing codes and helps maintain system functionality without excessive buildup.

While other considerations such as the presence of grease being a minor issue or cost implications may factor into decisions regarding kitchen design or waste management, they do not address the specific conditions under which grease traps should be used according to plumbing codes. Therefore, the focus is on the inability to install an interceptor as the primary rationale for opting for a grease trap.
