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)
- If included, irrigation systems must be audited by a professional certified by a WaterSense labeled program and include a controller or soil-moisture sensor that meets specified criteria. After June 1, 2013, controllers used must be WaterSense labeled.
- Verify the irrigation system operates leak free without creating overspray onto non-vegetated surfaces.
- 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.
