Certainly yea for all that.
Mother’s old pressure cooker canner is still around.
We’d have to get a new seal, I’m sure.
What about the pressure valve thingy on top. That need replaced? Should we just get a whole new package?
All pressure canners are different. I have one that does not have a gasket, it’s a metal to metal seal.
There are pressure canners and pressure cookers. If you want to pressure can, you need the canner, which can also cook. Cookers can’t necessarily can.
Yes, new seals and stuff would be good. Rubber tends to dry out with age anyway, but with the kind of heat that pressure cooker/canners produce, that’s going to happen even faster.
Do you have a co-operative extension nearby? They can help.
