We also have had problems with leaking systems in the past. This year we used as few of the brass tees and reducers as possible. I know, I know, if you use enough teflon tape it won't leak but by avoiding joints it will also help. Another thing we have found is that some of the tanks take a lot of torque to properly seal. No problem this year but last year it took two guerillas to crank the fitting in tight enough.

BTW installing the Norgren regulator backwards will give you the symptoms you mentioned.
