What would be the fixture rating for a bar sink with a disposal in a private residence?

In plumbing systems, particularly for fixture ratings, a bar sink with a disposal typically has a standard demand value assigned to it that reflects its expected usage. A fixture rating of 2 for a bar sink with a disposal takes into account both the sink itself and the additional load created by the disposal unit.

The bar sink is generally used for light food preparation and beverage service, and while it usually carries a lower rating than a kitchen sink due to its intended use, the addition of a disposal increases the demand. The rating of 2 indicates a moderate level of usage that is appropriate for its application in a private residence. Ratings like this are established based on plumbing codes and standards that guide how fixtures are rated based on common use scenarios.

Some of the other ratings would imply either lesser or greater demand, which would not accurately describe the typical use of a bar sink with a disposal. This understanding aligns with standard plumbing practices, making a rating of 2 the most suitable choice for this scenario.
