Question: 1 / 400

What type of toilets should all two-piece toilets be in terms of water consumption?

1.0 gallons per flush

1.3 gallons per flush

1.6 gallons per flush

The correct answer reflects standard water consumption guidelines established for toilets. Two-piece toilets are typically designed to adhere to the efficient water use standards that were mandated in the United States, particularly under the Energy Policy Act of 1992. This legislation set the maximum water usage for toilets to 1.6 gallons per flush, which has become a common industry standard.

This threshold was established to conserve water without sacrificing performance, as older toilets often consumed much more per flush. Therefore, the 1.6 gallons per flush specification is crucial for both environmental conservation and regulatory compliance, making it a key requirement for modern toilet design.
