Search the published residential Excess Flow (EFV) and Earthquake Sensitive (ESV) lists by exact DSA label ID, manufacturer, or model. Each result stays tied to its list edition and PDF page.
The source PDFs provide certification dates but no status, expiration, revocation, or renewal field. DSA says installation remains under the local building department. Verify the current program, reference standards, product configuration, and local requirements before use.
