My pressure cooker is leaking and it seems that ill probably have to replace the gasket. My question is: are my jars going to be sterile at the end of a leaky hour or should i just sterilize again next weekend with a new gasket?

If its maintaining pressure in the desired range, youre good. Try wiping the gasket with some cooking oil and adjusting it into the proper place before you give up on it.

I only have a pressure cooker with a rocker so i dont know what pressure its maintaining but i will do the cooking oil and see.

Did it make the rocker rock back and forth like it normally does for the entire cycle time?  And did it still have water in it at the end of your run.

 

If you answered yes to both of these questions, you should be fine.  And Mikey's advice is golden, but it doesn't hurt to get a replacement gasket before the one you have gives up the ghost completely.

i did the cooking oil then tried again and it still leaked .. i did goof up and run out of water last time and distort the bottom of the cooker aswell as burn the shit out of my bag and jars so i assume i messed up the seal when that happened .. do you think i need a new cooker or a new gasket? also do you think i should noc my jars or wait for a new cooker/gasket?

A warped cooker is a bomb in waiting. Get rid of it before it gets rid of you. I'm not kidding, it's dangerous if the metal warped. It's hardened aluminum, but if it runs out of water, and warps it has been weakened, and it's hardness compromised.

Others are gonna give their advice on how dangerous it is to use a PC that has ran dry. I’m just gonna say they nobody should ever run pressure cookers on high. You only need enough heat to maintain a constant hiss. For me that is about number 3 on my stove. Even if it did run dry, that is not enough heat to damage my pc or melt shit. 15 psi is 250f at sea level no matter how high or low it is. Once that water and steam is gone there is nothing to regulate the high temps of having a stove on high.

no the rocker didnt move at all sadly .. there was also no water left,. id rather buy a new gasket but i dont want to buy one if its really the cooker itself that i need to replace

it does however seem unlikely to be a bomb as it seems to have no real pressure build up but either way it seems i need a new one  :dry:

You should look up an instruction manual for your pressure canner online, it will answer your questions better than we can.

is it worth the extra $40 for the extra space and the gauge? or should i just get another 8qt for $30?

Also am I correct in thinking that I could buy an 8qt and a psi gauge and pop that little black rubber plug out of the lid and replace it with the gauge? Screenshot_20190210-001804_Amazon Shopping.jpeg

That little black rubber plug is the safety relief, for when something finds a way to plug the rocker vent.   It keeps it from becoming that bomb.  If you are handy with metal work, you could fit the lid with a gauge  too.  But I wouldn't give up the relief for a gauge.   A jar could break inside during a cook, and something could plug the rocker vent, so you need to keep the relief.

 

BTW, I have had several of that same Presto (one is a Sears, made by Presto) PC for pushing fifty years, and all of them have been stainless steel.  I don't like aluminum.  If the stainless goes dry, it's not as likely to warp.  I like to cook all kinds of things in a PC and aluminum is poison in food.

That presto is the exact one I use. But Alder is correct, if you can afford a stainless steel one, those are the best.

And you really want that guage too.
