I am familiar with thermostat actuation, but Vernatherm elements are more mysterious to me.
When I tested my Verna on the stove today, the piston extended fine, but would then only go back down by merit of moderate to heavy pressure. Is this normal? I realize the Verna valve is spring-loaded, and that is what pushes it closed, but should it be difficult to push the piston back into the down/open position, or not so much? I would say the level of pressure required would be similar to that needed to crush a large jelly bean b/t your fingers, maybe a bit more.
Thanks
