wtf are you talking about?

whats so hard to understand about i boiled 4 quarts of water on a stove in my PC without the lid on it, used those 4 quarts, later came back to put the lid on, and it now doesnt fit because the grooves are offset about a quarter inch in 2 spots.


theres no getting around the fact that my pc expanded and now doesnt interlock. i didnt rapidly cool it, i didnt try to put the lid on hot, i didnt leave it on the stove with no water in it.

this is no fault of my own i can assure you. i didnt do anything to warp it. i know the rules of expansion and heat and rapid cooling and everything else.




Cool, just want to make sure.  A lot of people are quick to blame a product before realizing that they did something the product wasn't designed to do. :thumbup:

Good luck with the warranty, you should be able to get a refund or a replacement.

My lid won't go on if it's "backwards".  Did you try turning it and putting it on the other way?

OMG, you read my mind! I don't have one of these but that was the first thing that I though of when I read this... I wasn't going to ask. I wanted to buy one just to find out.

I've panicked and had to 'Open Wide' and 'Change Feet' on many occasions. The good that can come of this is the OP will have a working PC again. I very rarely hope that someone is wrong about something.

Put the lid on the stove and let it site on the burner on medium for about 1hr and 36 minutes, then soak the pot in ice water :lol:

Nah, but I've had my presto for about a year, and it's seen 25-30 cooks with no problem. I've cooked food in it, canned food in it, sterilized grain, boiled water, hell just about a fair share of everything. Lid on, lid off, the only thing that I bother to do is clean the purge holes and clean/lube the gasket every 4-5 cooks. 16qt.

As RR stated the older ones are pretty much bullet proof.
The new ones are thin compared to the older ones.

But they are affordable (He would say cheap) and with proper care will last.
I've been using mine (new style thin one) for almost 7 years, pretty much every weekend.
I hate to see Presto get a bad rap, as far as hobby use goes it has a lot going for it, if I had a mushroom farm I'd get the AA and why not? It would be a tax write off anyway as a business expense.
Hey! I wonder if I sold at the farmer's market and needed equipment...that's another post I guess.. :offtopic:

I've been running it for 5 and 6 hours straight sometimes.

Hey OP, if you put it upside down on a glass table does it wobble?
Perhaps it got dropped...blame the cat?

If it's just a bit off round I'd put a car jack inside it and straighten it out.

i rock 2 presto's at a time, been doing it for years before even getting into mycology

we can our own beans, tomatoes, corn, and lots of other things so was using both of these way before i even started using to sterilize, and been working for a year in a half in this hobby as well..

also have a smaller presto that i use to do my agar and LC's

If you cooled the metal using water or some other means other than letting it air cool naturally, that will also warp steel permanently.  I used to get angry with my wife when she would pour tap water on our hot cookware.  Lo and behold, now we have a bunch of kitchenaid cookware that has all rounded bottoms. :rolleyes:




thanks man, i have rounded cookware and i wondered how it happened. they're used so it might not be my fault, mind you.

what about pouring burning hot tapwater?

You're welcome. :thumbup:

But no, using hot tap water is still a no-no, unfortunately.  The tap water is probably still way below the temperature of the surface of the pan.  Water can absorb a tremendous amount of energy, especially right at the point when it turns from liquid to a gas (evaporates/boils to steam).  When the water takes this heat away from the pan unevenly, the molecules in the steel contract and the once smooth crystalline structure of the metal changes and becomes stressed, which warps the metal.

There are a few other problems with this as well - one is that even if you submerged the pan all at once in hot water, it would still cool unevenly as it turns much of the water around it to gas.  Also, you can only quench the surface of the steel right away, while the metal that isn't on the surface of the pan would cool at a different rate.  The third problem I can think of off-hand is that the metal on a pan is usually heated unevenly since the heat source is only contacting the bottom.  The top surface and the sides of the pan are considerably cooler than the areas touching the heating element or directly above the flame.  Since it's not uniformly heated to begin with, quick cooling causes damage.

Slowly air cooling cookware is really the best way to make sure it lasts.
