Yup, filling this line with water would have made this job easier.

Speaking as a pool man who has no choice but to pressure test lines all
the
time, it passes my understanding why anyone would ever want to pressure
test
anything other than a fully flooded and bled line. Water being
incompressible, any leaks show up immediately. Air on the other hand can
leak out happily for some time before registering a significant drop on
the
usual semi-sensitive gotta-tap-it-to-see-it gauge often used for this
type
of thing. Of course I know nothing about PEX or radiant systems.
