Store It Foods

Is that your standard operating procedure?  If it is, then it may be time to give that a second thought.  Is that seal replaceable?  Is there anything else wrong with your pressure cooker?  Is it too large, too small, or lacking in some other respect?

If it is only a part that is causing your problems, why not save some money and replace only the part?  Yes, parts for older appliances may be unavailable, but don’t assume they are unavailable.  Check to see if there is a source of parts for older pressure cookers.  The same advice applies for blenders, apple peelers, sauce makers, grain mills, etc., etc.  Online searches are easy to undertake, and may provide you with positive results.

On the other hand, don’t bother with parts when it is cheaper to buy new.  Unfortunately, that is sometimes the case, and you also need to be aware of that possibility.
