Seismic Valve Installation
Seismic valve installation is becoming mandatory by legislation passed to protect life and property. These valves are designed to automatically stop the gas flow in the event of an earthquake with a magnitude of 5.2 or greater. NorCal Welding works with contractors and plumbers to install seismic shutoff valves on the customer side of PG&E’s gas service. Our pipe welders have over 40 years of combined pipe welding experience. We utilize LEL detectors to ensure safety after the gas has been turned off and the lines evacuated.
