: Pressure Canner Testing

  • 05/22/2018 9:00 AM - 11:00 AM

: Canning season will soon be here and Washington County Extension is offering testing of dial gauge pressure canners. Pressure canners with a dial-type pressure gauge should be tested each year for accuracy. Canner lids will be tested from 9:00 a.m. - “ 11:00 a.m. on May 22 and June 5. Lids may be dropped off at the Extension Office prior to those dates and picked up after testing or you may wait while they are tested. There will be no charge for canners tested on these two dates. To have a dial-gauge canner tested, bring the canner lid only. The entire canner is not needed. The pressure gauge and all vents and openings in the lid will be checked for proper functioning. It is not necessary to test weighted or rocker-type pressure regulators because they cannot be adjusted and will usually remain accurate. Canner lids that can be tested are Presto brand. All Presto canners should have a stamp NP (for National Presto) somewhere on the canner. It may be on the bottom of the canner. Other brands made by Presto include: Steamliner, by Lakeside Aluminum, Kook Kwik, Maid of Honor (only models beginning with 620 as these were made for Sears and other companies made other model numbers) and Magic Seal (made for Wards). All-American and Burpee models cannot be tested with our tester. If you are unable to bring your canner lid on one of the above dates they may be tested on another date by making an appointment and paying a $5.00 fee. For additional information please contact the Extension Office at 319-653-4811.
