Weird Pumping Question?
I bought a pump where the needle points at 5hg when the pump is empty. It’s really difficult for me to tell if it ever corrects this when pumping up. Like…when it does start applying vacuum, and the needle is at 10hg, is it really at 10hg or is it actually at 5hg since it started there?
So I was curious if a few members that are experienced with pumping could answer a very unscientific question for me.
When pumping, how does 5-8hg feel to you, when inside the pump? Can you not even tell that anything is going on? Is the sensation so light that if you put a blanket over the pump and couldn’t see it, you wouldn’t really know if you’d lost seal and nothing was happening? This is how it feels to me when I get the needle to 10hg. I usually take it up to 12hg or so and around there I can actually feel some pressure going on but below that point, I can’t feel anything much. It is definitely doing SOMETHING before there, but not enough to cause any sensation.
Any personal thoughts appreciated, thanks.
