I am working on a high school project that includes a kitchen with both a pre-rinse sink and a three-tub sink that will have two faucets. I see that both pre-rinse sinks and kitchen sinks are among the fixtures that must be included in my water savings calculations, however the template defaults do not seem to accurately describe the number of daily uses nor the duration of the average use of these types of flow fixtures. Has anyone had any experience that might inform my decision about these figures? Thanks in advance.
