I was looking at an All American pressure canner on amazon today and it was cast aluminum, I thought they were stainless steel. If there aluminum why would I want to pay more than the 23qt presto?
The pesto is spun aluminum and the AA is cast Aluminum. There is a huge difference. Cast aluminum is heavier pound per pound and much more durable and will not warp very easily like spun aluminum which is why Prestos are not rated for flame source above 12000 btu's. Cast aluminum can be used as headers on engines.
I love my prestos and just ordered 2 more after reading about the T-fal models. The only reason why i would spend the money on a AA is if i wanted to start cooking on propane burners.
Prestos are the best models on the market as far as balance of value and commercial use. As long as you dont run it dry or rapid cool it, it should last a very long time. They come with a 15 year warranty i think, i know its more then 10, maybe its 12. Anyway thats 7 bucks a year per unit asssuming it craps out at 12 years.
People talk about how the gauges pop off, well they can if they are not on tight. Before every operation and even new out of the box, the gauge needs to be checked along with the pop lock (not sure whats called) but mine comes loose every 3 or 4 runs and before i started checking it everytime, i was in the middle of a cycle and the jiggler was rocking but steam and water poured out of the lock. Took the lid off after it cooled realized it was loose, tightened it back.
By far my largest complaint about 23 quart models is that the weight spins so damn fast to maintain 15 psi. Fast enough to where i ran my pc's at 12 psi according to the gauge until my buddy said that his spun fast as well. I thought the gauge was off because i learned using a jiggler which is a gentle rock.
Anyway i would toss that weight in a drawer. The rocker is so much better and weights can be taken off to get down to 10 or 5 psi. Its is gentle and steady and so much quieter. When i had 2 of the original weights going in my my kitchen, i coukd hear it out front by the curb. I did a experiment using the rocker that came with my 16's several years ago that didnt have gauges and put it on my 23 quart and side by side the original weights is spinning and hissing like a jumping jack fire work while the jiggler is rocking like on my grandpa on the front porch.
The other thing i noticed is you can run the heat much lower with jiggler and still maintain 15 psi and even requires less water for the cycle. My point is if anyone wants a presto toss the regulator that comes with them now and purchase the jiggler style regulator. When i use the jiggler a gauge isnt even required, its just a bonus but i actually thought about removing the gauge and plugging the hole. Regulators need to be checked and calibrated once a year so just how accurate are the gauges for those who have not checked their gauges? Just buy the dang jiggler and it wont matter.
Presto is my recommendation for home hobbyist.
Pictures left to right. Piece of shit stock regulator for 12.99 at Amazon if you need to replace it or the awesome regulator that is much quieter, allows for less water usage per cycle, negates any inaccuracy in the pressure gauge, allows for less heat to maintain 15 psi.
