Gas Shutoff Valve Certification for Residential Structures

• DSA certification is currently for residential structures only.
• DSA reviews the report provided by qualified testing laboratories and certifies the product meets the applicable standard.
• DSA certification does not cover manual shutoff valves or equipment/appliances incorporating shutoff valves.
• The installation of gas valves is under the jurisdiction of the local building departments. Contact your local building department for specific details regarding permitting, installation, and inspection requirements.
• DSA certifies the ESV and EFV under the current standards which become effective six months following the publication of a new version of the plumbing code. On the effective date, manufacturing of the ESV or EFV must meet the current standard.
• DSA publishes lists of certified automated gas shutoff valves, as well as a list of qualified testing laboratories for gas shutoff valves. 
• Gas Shutoff Devices Comparison Table (PDF) This document reviews the three types of gas shutoff devices with a description of how they work and the benefits of each type.
