Someone else may disagree, but I don't see any reason why not. If the weight is designed to rock, that's the same as the All-American, and that company specifically says the gauge is there to assist in monitoring, but the weight is what counts.

Generally the weight is more accurate than the gauge anyway, because it's machined. The gauges on the Presto and All-American are both cheap (relatively speaking) and very susceptible to even the slightest bump.

My old Presto canner came with a three-piece weight 5-10-15, which is still available through the company. (Not relevant for you perhaps but definitely for others.)

I have read on the NCHFP site that there are dial-gauge canners where the weight only serves to seal off the port and does not rock. I've never run across one of those, but if your weight doesn't rock despite the fact that the gauge shows 15 psi, then you do have to rely on the gauge.

The weight that comes with it will rock at 15 lb. of pressure, however, that is not it's real function. It is as Carol said, it is to allow pressure to build in the canner. It is called a "counterweight".(Carol, they do rock at 15 lb.) You can buy the three piece weight set and use it for pressure on a dial gauge canner. I just started doing that.
You still leave on the gauge, just rely on the weights, though, instead. My gauge does read 11 lb. when the 10 lb. weight on mine rocks steadily, so that is perfect.
I figure if we ever get to the point where we can't test the gauges I can still can. This is also a good solution to those who cannot get their gauges tested. Many extension offices no longer offer the service.
So, yes, technically you could use the counterweight and process at 15 lb. pressure, but you would use the processing time for 10 lb. Using 15 lb. pressure is not recommended for folks unless they have to adjust for the higher altitude.
Presto came out this year with a canner, can't remember if it is 16 or 18 quarts, and it is only a weighted gauge canner. As far as I know Walmart is the only place to sell them. I talked to someone from Presto on the phone and that was what the person told me.

Thank you to everyone who helped with advice.

I wrote to Presto and they wrote back in one business day. I'm impressed with that. The lady told me that I CAN use the counterweight when canning at 15 PSI and then use the gauge just as a reference (the same All-American).

Additionally, I can purchase Presto Regulator #50332, which is a 3-piece pressure regulator with 5-10-15 PSI, and use that instead if I want to can at 10 PSI. She says it WILL work.

She also recommended purchasing owner's manual #72720 as it is the one for a weighted gauge pressure canner. She says the cost of the owner's manual through Presto is $5.00. The 3-weight pressure regulator is about $11.00 or $12.00, depending on where you buy it.

So, effectively, what we've got here is a much less expensive version of an All-American canner - a weighted-gauge canner with a dial for reference!

I don't want to depend on a dial gauge. I live in an area where people act like they've never heard of testing a dial gauge. I called three county extensions within a 30-mile radius of my home, and none of them test gauges.

I can send the gauge to Presto, but, again, I don't like that idea as they said it can take weeks, and anyway, I prefer listening to the sound of the canning going on when I can something that takes more than an hour.

Anyway, Presto Model 01755 16-Quart can be used as a weighted gauge canner if you want, or if testing gauges just doesn't work for you.

I could have sworn my Presto is an 18qt... it has the gauge and the weight, but it rocks over 15lbs. So your main point of this thread was not that the canner has both a weight and a gauge, but that there's a 3-way weight available, or the 16 is different from the 18's & 22/23 qt models? That means that it will exhaust or limit the pressure at whatever you set it, 5, 10 or 15? So I won't have to lower the flame when the desired PSI is reached?
