The only fitting in the kit that matches the threads of a standard hose bib
appears to be some sort of anti-syphon valve. Screw things together, apply
pressure and the adapter (?) leaks like crazy.

What am I doing wrong?

HF is no help... 'Send it back.' Good advice but it's here and the emitters
work and tubing is tubing and the plants don't care, so long as they get a
drink now & then.

Any help would be warmly appreciated.
