WaterSense-labeled homes are verified and certified to meet EPA’s Mandatory Checklist and achieve EPA’s water efficiency criteria that the home will use at least 30 percent less water than a typical home anywhere in the country.  However, in some regions, additional water-efficient features may need to be adopted to meet the 30 percent threshold.

The Mandatory Checklist helps ensure that all WaterSense-labeled homes contain, at a minimum, a set of features that assure quality performance in addition to efficiency. The Mandatory Checklist requires that all toilets, bathroom sink faucets, and showerheads be WaterSense labeled, and that the home be free of water leaks from all fixtures, appliances, and water piping.

The mandatory checklist is paired with the measurement requirements of the WaterSense Approved Certification Method (WACM) to ensure that a WaterSense labeled home is both water-efficient and high-performing.  

WaterSense-labeled homes—like WaterSense-labeled products—must be third-party certified to meet EPA's efficiency and performance standards. The WaterSense Home Certification System outlines the process and procedures for the verification and certification of WaterSense-labeled homes. Verification is a key component of the certification process. The specification is applicable to single-family homes and multifamily buildings.

Home Verifiers

The required WaterSense verification is a simple process that can be done in a single visit, often in as little as one to two hours. 

For a home to earn the WaterSense label, it must be verified by a trained and approved WaterSense home verifier and certified by an EPA-approved HCO. Verifiers are trained, evaluated, approved, and overseen by the EPA-approved HCOs to ensure they have the capability and competence to verify homes in accordance with the WaterSense Specification for HomesFind a WaterSense home verifier.Under the WaterSense Specification for Homes, a trained WaterSense home verifier will verify that a home meets the required efficiency requirements of the HCO’s WaterSense Approved Certification Method and that it includes all the features of the Mandatory Checklist for WaterSense-Labeled Homes.
