Anti-siphon hose bib.


Most likely required by code. It sounds like it needs fixing or
replacement if it's leaking continuously.

Every house I have ever owned here in Phoenix has had them fastened
onto the hose bib with a set screw that usually needs to be drilled
out in order to remove it. They tighten them down with a regular screw
and then cut the head off flush to the anti siphon fitting. So, you go
to the home/hardware store, buy a new fitting for a few bucks, and
replace it.

They're used to keep from sucking hose water back into the house lines
if the main house supply loses pressure. It's a good idea to have one
on there.
