Pumping Issue
Hi,
I couldn’t start the thread in the pump section so I’m posting here. I have a VacuTech pump with a 2” flared cylinder. When I go in the pump 90% erect and pump to about 3hg, I immediately get a significant increase in size in the pump but a few seconds later, I go down to a slightly smaller size than my initial size when entering. The gauge shows no loss in vaccum. Any suggestions?
Thanks
