Jeff after talking with you on the phone the other day have you had that pressure head checked out ?

As I was saying on the phone, the Taylor Wharton LD50 that I have holds pressure at 10psi rock solid, it also has never vented.

At 22psi I bet LN2 comes out like a jet, 10psi is bad enough LOL

I have had this last full refill of LN2 for over a month and lost almost no LN2.

When I do get it refilled to a full tank it does take what seems like a long time, hours actually, to build up enough pressure to get a good flow of LN2 out. I usually let it sit over night before use and all is good. I was told that when full there is very little space at the top for pressure to build up when full. Ron at Under The Ice has the same problem. I will have to ask hime if his vents also.
