I am going to order 2 sets of weights and went tubes to convert my old pressure cookers . That will give me a total of 3 # 7 cookers and the canning will go much faster. I've got my grandma's pressure cookers.

Understanding the Context

Neither are in working order. The one I want to work on first is a National #7. The petcock is broken. Everything else seems to be in working order.

Key Insights

Because the color of the pressure guage matches the metal label on the lid, it probably needs to be changed... Several years ago I bought some 5 QT. Aluminum Pressure Cookers, for survival camp sites. (Note: they are still in the boxes and have never been used). I think this time I will buy about (5) Five "Stainless Steel" pressure cookers, to cache at new remote sites.

Jeff Unfortunately, the public, like you, is afraid of steam even though most every american house has a water-heater, which is basically a ticking time-bomb, and uses things like pressure cookers, etc.

There are several videos about using an InstaPot for pressure canning. BUT the food safety agency does not recommend using pressure COOKERS for canning. When you fight fire with fire, the whole country burns. Kaizen D.
