when i started i did have many crack, more than i should have. was heating up PC as i loaded grain jars, so the temp difference was too much once the PSI started rising, and they would crack. kinda like sometimes if u open ur PC too quick when its done, they will crack occasionally. took a month to realize what was happening back then 
when i would search for same problem, response was always to let PC sit overnight or cool more before opening, which i always did, so i was confused. took about a month until i realized pre heating can do similar thing

Hmm interesting. I load my PC with water from a secondary faucet that puts out water at 160F, then I put in the filled jars. Seal it up and set the cooker on the fire. Have not had breakage from starting with hot water. Was the water in your cooker boiling when you put in the jars and sealed up the cooker?
I tested the stopcock on the 941 today. And got video of the stopcock popping. This valve didn't leak a bit before popping like I thought it would. I'm pretty sure the other valves I have do, I will have to test them. The valve popped around 28-29psi. Video isn't the greatest. It was zoomed in and it caught me a little off guard.

no, never boiling, but it would get steamy. i dunno what else it could have been. when i started, the jars weren't old or used. maybe just dumb luck.

I didn't tape the coins to the jiggle weight, what I did was put a few of them in a piece of foil and then fold it over a few times and mold it over the top of the weight. It can sit on top of the weight like a hat and be removed if I want it to go back to 15psi. I siliconed a few pennies on top of that as well.

Bl. I have broken a few jars the same way. But I usually heard it happen before I put the lid on. I would fill the pc with water and start heating it up while filling jars. If I wasn't fast enough, the grain in the jars would be room temp and the water in the pc would be near boiling. I would start setting the jars in the pc and I might hear one crack. I have only have one crack on cool down. It was because I took it out way to soon. Like as soon a the pc hit zero psi. But the inside of the jars were still 250+.
Another great upgrade would be to purchase the inside stand that is used on the electric sterilizer. Or to make a 3 inch high stand to completely raise your jars/bags or of the water. I don't know why it's so different, but I really like how things look when they come out of the sterilizer. Aa calls it dry steam.
Btw, nb, or bl. which hot plate do you use. My phone will not let me scroll up to see which one of you use it.

Despite the express admonishments of AA not to use a glass cook-top stove, that's what I use. I've been thinking seriously about getting a dedicated hotplate (electric) especially now that temps and pressures are going to be higher since conversion to a sterilizer from a stock PC - so I'll be monitoring the responses of others.

Huh? You mean 20psi is where it starts says caution? The top of the caution area is 30psi. Or do you have a totally different gauge? Pics?

Inocuole. Shit works man.
I had mine at 19-20psi. No hissing (noise) Less water (faster heat up time) Less run time. Also, less energy. Had my dial on 4 on the stove and it maintained right around that area.

tahoe said: Dark. You would be fine doing that. A pc is not going to blow up with a rubber blow out plug in place. I feel confident saying that most if not all quality pressure cookers can withstand 100psi. I would imagine the blow out plug Will go well before that. No one is going to make a pc that cooks at 15psi but is structurally unsafe at 25psi. It's just not good. Also think about propane canisters, air compressor's, etc. Those hold 80psi plus with no problems. Pc's are built as thick if not thicker. A pressure cooker truly blowing up is a thing of the past. Now keep in mind that a puffed up grow bag can block the jiggle weight, the blow plug, or valve. So take precaution not to let that happen.
The main things that would suck if a pressure cookers blow out plug went would be, scalding hot bird seed soup spouting across the kitchen. And that might not happen. Most likely be a spout of steam, some noise, and mild heart attack.
My aa pressure cooker creeks and pops also. It can be noisy and is almost always startling. On my 921 it was my indicator that it was getting close to 15-20 psi. I believe the noise is caused by the lid reseating itself as the pressure rises. I usually put a cool lid on a warming up pc. The lid and pot were once a solid piece when talking all American. As the pressure builds it pushes on the lid. The lid lifts a little and reseats itself in a different position.
My AA makes absolutely no noise heating up or running. Just an added bit of useless info I recently put some Vaseline lotion on the sealing part. Slides off so easy now. Before I had to hit the metal that holds the locking nuts with a hammer to jar it loose. Things is a dream now.

N.B.
I also use a glass stove top. No issues so far. My AA sits on a circular aluminum plate. It came with my distillery kettle for electric stoves because of the voltage thing that switches off and on I guess the idea is for the aluminum plate to help maintain the even heat so I also run the aa on that. I wonder if it may help retain heat from going to the outside edges of the stove. Mine is a 915 so it doesn't go that far out over the burner either though.

I'm sorry for all the posts, finally figured out how ot multi quote here.
Yea I will take your advice and do that. Plus the gauge is off anyway (sits about 2psi above 0 stone cold). I don't know how old this is. got it from ebay.

Thought twice about it, but then said, what the heck, wife's out with her gal pals, if I wreck the kitchen, so what! To grow mushrooms, you also have to grow some balls, I guess. 
Configured this way the "sterilizer" is more energy efficient than when run as a PC. My usual equilibrium is a "4" on the 12" stove-top as a PC. Once everything is up to temperature, I'm running a setting of 2 with the safety relief valve. The reason is obvious. This setup is not leeching hot steam, so far less heat energy is lost. Therefore, less heat is required.

Here is some eye candy for a Sat afternoon.


Just a Craigslist find that I never get tired of looking at. I sold it to a member here years ago. I already had 2 that size. I'm strange, I know. 
I've done the coin trick on my 941 and it works, but the toggle works so much better. Whatever works for you.

I too use a glass cook top for my 921. That is why I was asking about the hot plate. My 921 had some rough areas that would scratch the cook top. The wife was not cool with that. I got out some sand paper and a buffing wheel and polished the bottom of the pc to almost a mirror finish. That took care of the scratching.
I forgot that I was cooking seed 24 hours ago in the sterilizer. It's on a 24 hour timer. I love it. So that is why I am looking for a decent hot plate for the 921. So that I can plug it in to a timer and set the heat. That way I can set it and forget it. Cooking somewhere between 15-26psi should be easy enough to set up.
Just walked into the garage and found this. The release valve was hissing a little and about to open.

Dear LORD!!! I'd have soiled my undies! I REALLY like the upgrade now that I've used it. I can see myself getting quite comfortable with this in just a few runs. Tahoe, you 'da man!

That is scary for sure. 
I'm lucky to have a gas range but the hood is much too low for the 941. I have to take it outside to run it on a propane burner. The toggle on my 1925x lets off way below aerow.thefox's. It blows at about 24 lbs. I have yet to see the rubber plug blow on any of my AA's.
I would make a suggestion and that is for those of you with the funds, get a basket and a tube for your conversion so that you can "dry steam" your agar, utensils, and other things. It is so much more convenient than a PC version. It also is a slick way to do bags, as you can just space them in the basket and, when cool, take the basket out of the unit and quickly put into a brand new trash bag and seal. The bag is sterile and you can effortlessly move it to your clean room from the stove. My contaminate rate is almost null using this technique, as I don't have to fool around pulling the bags one at a time from the stove to... wherever in open air. Just a thought to make it a cleaner way to do things.
Tahoe definitely is the man on this TEK. Again, great job.
