Your business site may be located within a city, county or other jurisdiction that requires an earthquake valve to be installed on your natural gas line. If so, it must be installed by a qualified plumbing contractor, downstream from PSE's natural gas meter.

If you plan to install an earthquake valve, call 1-888-225-5773 or send an email to customercare@853961.com and schedule PSE to have your gas service turned off during your installation. When your installation is complete, we will turn the gas back on.

PSE requires 60 days’ notice to become a natural gas transportation customer, you must enter into a one-year delivery contract with PSE, and you must install a telephone line for PSE telemetering equipment at your natural gas meter.
