van hatton said: The higher you go the less is required to reach sterilization temperature. If I remember right . So it's calibrated to be 15psi at sea level.
What do you mean it'll only go to 13.5? Is your rocker moving a ton. My presto generally would rock around 14psi just throw some quarters on it if you don't want to look up the elevation chart I'm pretty sure is in your PC Manuel /online
Edit: and now that I reread that page I feel like a jackass apologies
Ok I think I see what you're saying. Idk if you are right, but I think I see where I was thinking a little bit too much in one direction. I just thought at a higher elevation the rocket would start rocking at a lower pressure as well, because it is literally rocking when it says 13.5 But gauge calibration could be the case. Definitely is A thing but idk what that means for the pressure I'm experiencing. I'm just debating about this and also with myself so yeah man it don't matter.

No the higher you go the less psi it gets so if youre cooking at 15 psi at 5000 feet youre only cooking at 12.5...
https://www.hippressurecooking.com/pressure-cooker-psi-faq-the-stuff-you-didnt-think-to-ask/ here is the site there is more haha sorry ... not sure yet im doing some g2g tomorrow the last time i ran them like that i didnt have a good sealer and almost every bag got trich besides a few

If the gauge is calibrated to read 0 at 14.7 psi (sea level) then we'd estimate it would reach 15 psi internally, while the gauge itself reads whatever elevation is lower, which is what I was going off of. However if you're that high, you should be around 11 psi, so it would technically be 3-4 psi lower than 15 psi when the weight would just begin to jiggle. In that scenario, you can always add weight so it reaches the same pressure as the people who sterilize at sea level.

So a higher elevation its still at 15 psi basically just reaches it at a lower psi? What i got from the chart and i didnt read anything haha but the higher you go the harder it was to reach 15psi ...
Then if youre right mad why does it say to add more cooking time?

Ok. That's what I thought. Besides the fact that 11 psi is incorrect at my elevation, because I'm not at 4000 and I'm at 13.5 psi.
Adding weight to a AA rocker though? How would one do that? (Not mine but I wish, just borrowing)

Mad just basically said van hatton is mistaken. (Although he makes a good point) but Mad is saying add weight to reach same pressure as sea level, and at my higher elevation the rocker does in fact start rocking at a lower pressure.
And I am also saying that the chart is not accurate. My elevation is a non debatable 7000. At least. And I am reaching 13.5 on a pressure cause calibrated for sea level.

Ya mine is saying id be at 13 and my rocks at a hair under 15 ... i see what mad is saying, now that you explained it haha ..
I just run mine longer then normal just cause i have oats and can but i did notice when i moved up this high and ran them at a regular time i was getting more bacterial jars till i kicked it up and extra 30

I haven't even tried less than 120 minutes yet with jars. Immediately first time I pressure cooked I did 2 hours and haven't had much issue. But I usually am around 5000. Confusing shit, but interesting none the less.

Tape coins onto the rocker, or if you're just a bamf, another rocker 
no noises at all 
Yeah if you get it up past 15 psi, and if it's actually calibrated to 14.7, you'd be sterilizing with an overall pressure of 29.7, which is what it would be at sea level. That is if ofc the gauge is calibrated to sea level, and for the life of me I can't find anything on that, but I do remember some time ago hearing about how the gauges on most pressure cookers are calibrated to sea level

That site i linked said it was calibrated at 14.7 at sea level ... so making the weoght heavier help the water from drying up?

I remember reading that too Mad, it was pretty recent. Would make sense to me about their calibrations..
Whilst we're on the topic if my PC is 12PSI and I'm less than 1k ft altitude should I just add 30 mins to all grain times?

If there's no noises or steam escaping, 2 hour cycle doesn't even lose half a qt of water lol, you shouldn't be having any drying out issues when you do this. Adding weights just makes it operate at a higher pressure without losing any water. Very nice IMO

That's what I did 2 quarters I just have m gauge read 15.5 the whole time.
How high could I go without blowing the overpressure plug? I feel like it was 18 but IDR.
Thanks for clarifying mad

Hm, I thought that regardless of what the gauge said, the rocker/weight would tell you the PSI you're reaching. So with a 15PSI weight and hissing/shaking, you're at 15PSI.
I'm between 400-700' elevation and my rocker never goes past 13.5 PSI before going crazy. Even when I turn it down a bit to relieve the spinning/shaking, it still steadily hisses a bit and spits out a few flecks of water along the side of the weight.
Should I tape some quarters to it or what?

Well both of my prestos are warped due to the water drying and i hate it... if i ran it at 15 psi for the 2.5 id have to put water an inch or two up the jars or more for it to not be dry...

Ouch that happened to my old 16 qt.
It definitely helps with water loss. I'm thinking about adding another quarter meow
