WaterSense: Meets EPA Critera WaterSense Seal An EPA Partnership Program


The required WaterSense inspection is a simple process that can be done in a single visit, often in as little as one to two hours. An inspection includes the following steps:


  • Verify that WaterSense labeled products have been installed.
    • Verify proper performance through flow rate tests.
  • Conduct a performance test to ensure that no more than 0.5 gallons of water is wasted before hot water arrives at the furthest fixture from the source.
  • Confirm all optional features (e.g., clothes washers, dishwashers, drinking water treatment systems) meet the specification's criteria where installed.


  • Ensure the Water Budget Tool is used, and verify that the tool has been correctly and accurately filled out.
    • Measure the area of turfgrass and water features.

Irrigation System (if installed)

Resident Education

  • Verify that a resident's manual* detailing usage and maintenance of the home's indoor and outdoor water-efficient features is provided and includes:
  • Operations and maintenance manuals for all water-using equipment
  • If an irrigation system is included with a single-family home:
    • a schematic of the irrigation system
    • an itemized list of all components
    • copies of the programmed irrigation schedules with information on reprogramming
  • General information on water-efficient appliances that are not included in the home but could be added at a later date (such as clothes washers or dishwashers)

*Builders must also provide manuals for building managers in the case of units in multi-family buildings.
