  (2) The maximum flow from a shower head shall not exceed 2.5 gallons of water per minute at a constant pressure over 80 pounds per square inch.

  (3) The maximum volume of water per flush from a urinal and the associated flush valve, if any, sold, offered for sale, or distributed in this state before January 1, 2014:

    (A) maximum flow shall not exceed an average of one gallon of water per flush; and

    (B) the urinal and the associated flush valve, if any, must meet the performance, testing, and labeling requirements prescribed by the American Society of Mechanical Engineers Standard A112.19.2-2008 and Canadian Standards Association Standard B45.1-2008 "Vitreous China Plumbing Fixtures and Hydraulic Requirements for Water Closets and Urinals."

      (i) American Society of Mechanical Engineers Standard A112.19.2-2008 and Canadian Standards Association Standard B45.1-2008 "Vitreous China Plumbing Fixtures and Hydraulic Requirements for Water Closets and Urinals;" or

      (ii) American Society of Mechanical Engineers Standard A112.19.19-2006 "Vitreous China Nonwater Urinals."

  (5) For a toilet sold, offered for sale, or distributed in this state before January 1, 2014:

    (A) The maximum volume of water per flush shall not exceed an average of 1.60 gallons; and

    (B) The toilet must meet the performance, testing, and labeling requirements prescribed by the following standards, as applicable:

      (i) American Society of Mechanical Engineers Standard A112.19.2-2008 and Canadian Standards Association Standard B45.1-2008 "Vitreous China Plumbing Fixtures and Hydraulic Requirements for Water Closets and Urinals;" and

      (ii) American Society of Mechanical Engineers Standard A112.19.14-2006 "Six-Liter Water Closets Equipped with a Dual Flushing Device."

  (6) Except as provided for in §290.256 of this title, for a toilet sold, offered for sale, or distributed in this state on or after January 1, 2014 must be:

    (A) A dual flush toilet that meets the following standards:

(c) Nonwater-supplied urinal performance standards are the following:

  (1) A person may not sell, offer for sale, or distribute in this state a nonwater-supplied urinal in this state unless the nonwater-supplied urinal:

    (A) meets the performance, testing, and labeling requirements prescribed by the following standards, as applicable:
