| I'm new to canning. I bought at 23 qt. Presto pressure canner and it has been working splendidly. Today after the cover lock popped up into place, it didn't seem to seal like it usually does. More air and water was escaping than usual, and it was making a squealing sound. I stopped the process since I wasn't sure how this would affect the food. Has anyone seen this before? Could it be the gasket to the vent lock? If I stopped the process, can I try processing it again the next day? How does a break (with refrigeration) in between the two processes affect it? |

| Sounds like the gasket may need to be replaced or at least cleaned and oiled. Lime from water can build up there if you have hard water. I have never heard mine squeal but it does spit and vent for a bit until fully engaged. That's normal. I'd suggest cleaning in and around it well first and apply some vegetable oil to it. That often stops the problem. Also check the pressure regulator/weight vent for blockage and that can get plugged too. As to reprocessing. Jars and contents have to be hot when they go into the canner or the processing time is voided. So It all has to go back into the pot, be re-heated, re-jarred, new lids, and then fully processed.
