Reliability of old gas valve?
I have an older nat'l gas valve in my crawl that control a grill that is not used. I want to turn it to the off position but I am leary to do so because of its age.
Its about 30 years old and is a quarter turn handle valve that looks to have oil packing and a nut on the other side of the handle.
My experience with old valves is once they are moved they leak. Do these oil pack valves have a tendency to leak if they have not been used in many many years if ever?
