The maximum consumption of a water closet per flushing cycle is how many gallons?

• A. 1.28 gallons
• B. 1.6 gallons
• C. 2 gallons
• D. 2.5 gallons

Answer: (B)

The maximum consumption of a water closet per flushing cycle is 1.6 gallons. This limit has been established by the Energy Policy Act of 1992, which mandates that new toilets sold in the United States must use no more than 1.6 gallons per flush. This standard was implemented to promote water conservation and reduce overall water usage, as toilets account for a significant portion of indoor water use in households. While options such as 1.28 gallons are relevant as they correspond to newer high-efficiency models, they are not the federally mandated maximum for all water closets. Options above 1.6 gallons do not comply with current regulations aimed at enhancing water efficiency in plumbing fixtures. Therefore, 1.6 gallons remains the correct maximum consumption figure for conventional water closets per flushing cycle.
