Los Angeles Times (pre-1997 Fulltext) - Los Angeles, Calif.AuthorGARY ABRAMS DateJan 30, 1994Start PageSection Real Estate; PART-K; Real Estate Desk Text Word Count:653 I have installed hundreds of the valves since the 1987 Whittier quake and, in spot-checking with some customers, found that the valves apparently functioned properly in the Northridge quake, triggering in the 6.6 temblor. Some valves had been reset after the first quake and did not trip in the lesser aftershocks. Nuisance tripping is one of the most common concerns about the valves. But when the valves are properly installed, that should not be a problem. My valve is placed in a location subject to vibration from passing vehicles and has never caused a nuisance trip. Earthquake gas valves are normally installed by licensed plumbing contractors, not the gas company. Check with your plumber about experience and recommendations regarding the make of valve he or she prefers. Make sure that the valve selected is one of the more popular makes and carries State Architect approval.
