The bill defines a "watersense-listed plumbing fixture" as one that has been:
- Tested by an accredited third-party certifying body or laboratory in accordance with the federal environmental protection agency's WaterSense program;
- Certified by such body or laboratory as meeting the performance and efficiency requirements of the program; and
- Authorized by the program to use its label.
Current law requires water-efficient indoor plumbing fixtures in only three contexts:
- Builders of new single-family detached residences must offer the buyers toilets, faucets, and showerheads that meet the current standards of the WaterSense program;
- Tank-type water closets and flushometer toilets in new state buildings must meet certain standards that are either less stringent than or as stringent as the current WaterSense standards; and
- New construction and renovation of residential structures and office, commercial, or industrial buildings must meet standards that are less stringent than the current WaterSense standards.
Section 1 of the bill prohibits the sale of lavatory faucets, shower heads, flushing urinals, tank-type toilets, and tank-type water closets on and after September 1, 2016, unless they are a watersense-listed plumbing fixture. Sections 2 through 5 amend or repeal conflicting portions of current law.
