A project's installed water fixtures do not exceed WaterSense maximum levels.

When a project’s installed water fixtures do not exceed WaterSense maximum levels, the appropriate compliance path under the Water Efficiency Prerequisite for Indoor Water Use Reduction is Compliance Path 1: Prescriptive Achievement. This path requires product cutsheets as documentation to demonstrate compliance. The product cutsheets serve as verification that the installed fixtures meet the WaterSense labeling requirements and do not exceed the maximum flow rates established by WaterSense standards.
