If your earthquake shut off valve tripped and there was no earthquake, contact PG&E at 1-800-473-5000. One of our representatives will schedule the next available appointment to have someone come out and reset your earthquake valve.
If there is an area wide natural disaster occurring, PG&E response time will be based on availability. If you do not want to wait for PG&E service, you can contact a licensed plumber or contractor for assistance.
