Whenever I use the canner it seems to spit water out of the vent. If I turn the temp too low it doesn’t get to 15 PSI where I need it to be, but too high and it continuously leaks hot water. It’s gotten rusty and a bit indented, is this safe? How can I prevent this?

I’m actually curious if this is rust of mineral deposits from the steam. If memory serves, these canners are aluminum and as such, should not oxidize in the way that steel does (unless the vent pipe is made of a dissimilar metal). Perhaps try scrubbing the pipe with a mild abrasive and see what happens after that.
Are you in the US? If so can you take it to your local extension agent for a consultation? Or talk to a Presto rep?
$6.00 and two wrenches and you can replace this with a brand new vent pipe.

Even if it does get eaten through its just going to start leaking and will no longer pressure up. Remember its only 15 Psi, we all regularly travel down the road next to a truck and they’re tires may have up to 120 Psi in them and they have catastrophic blow outs all the time with cars traveling inches from them and nobody worries out about that.
Looks like mine. I take it in to get tested every year and every year they say “wow…that’s an old pressure canner” it is still going.
Look more like mineral deposits than rust, get some CLR and soak a rag and place it around the vent and see if that breaks it up.
Is a pigs pussy pork?
Just clean it or replace from stem if you’re that concerned
