A grease interceptor on the same floor as the fixture shall have what fraction of the liquid holding capacity of the fixture?

The correct answer is: 1/2

A grease interceptor on the same floor as the fixture should have half (1/2) of the liquid holding capacity of the fixture. This requirement ensures that the grease interceptor has sufficient capacity to effectively trap and separate grease and food solids from the wastewater coming from the fixture. Having a grease interceptor with at least half the liquid holding capacity of the fixture helps prevent clogs in the plumbing system and ensures proper grease management in compliance with plumbing codes. Option A (1/3), Option C (2/3), and Option D (3/4) are incorrect because they do not align with the standard practice of having the grease interceptor with half the liquid holding capacity of the fixture.
