Record Gauge readings and Regulator weights An accurate gauge and weight scale is required. A few inches of water only, no jars. (Add an extra inch or two of water for safety) DO NOT BOIL DRY - Vent 10 minutes as usual. - Regulator body only to start, record weight in Grams. - Record pressure point where jiggling Starts and Stops. - Adjust heat for a slow to medium Jiggle & record pressure. - Add one washer and repeat. Etc. - Keep records with regulator for next season These figures can be used to check or verify gauge calibration. Keep in mind, there are slight variations in weights of Presto and BTB components due to manufacturing tolerances. There could also be slight corresponding variations in pressure between components even of the same type.

Vent Pipe ID

I replaced the original 85608 Vent Pipe in my older model Presto 0178004 canner,
when i found the original had a slightly larger hole ID (approx .13" ID)
compared to a newly purchased 85608 (approx .125" ID).
(I have a newer model Presto 0178107 as backup, which tipped me off to the Vent Pipe ID difference.)
Although both new and old Vent Pipes have the same number,
the older one (.13" ID) gave slightly lower pressure regulation points than the new one (.125" ID).
I have no idea what caused the different Vent Pipe ID's in my canners,
but other YouTube videos on this topic might show this difference as well ?

Again, It is important to measure, record and save your own pressures wrt weights for later reference.
Do NOT trust or use other people's readings.

All my canners (and videos) now use the newer 85608 .125" ID Vent Pipe.

DIY PSI Increase Copper Wire Method

A DIY method of increasing the PSI is to use solid copper wire wrapped around the regulator body.
The increase in wire weight corresponds to an increase in PSI.
1 foot of bare solid 14 AWG copper wire will give about 1 PSI increase.
Values in the table below are calculated from nominal values and might not be accurate in all cases
As always, verify everything using your own scale and pressure tests etc.

Copper wire lengths required for PSI increase

From "Pocket Ref" by Thomas J. Glover  ISBN 1-885071-33-7 Feb 2004

Presto 50332 Reg & 85608 Vent Pipe  (5.56 grams = 1 PSI)
Bare Solid Copper wire stripped from house wiring

note: Canadian 14/2 copper electrical wire will have at least two strands of 14 AWG.
Double check gauge using a caliper and weight scale, as the bare gnd (3rd wire) could be 16 AWG.
