Free Pressure Gauge Testing. Call 509-735-3551 to schedule your appointment.

Free Pressure Gauge Testing

The long winter is finally gone, temperatures are rising, and the garden is being planted. Now is the perfect time to ensure your pressure canner is working properly, before harvesting begins! The USDA recommends pressure canners with dial gauges be tested annually. Why? Testing the gauge tells you whether your gauge is working properly. An accurate gauge is necessary to make sure your home canned foods are safe.
