Backflow leaking at screen outlet

The sprinkler system I had on my previous home did not have this screened opening on the line. Actually there is one on both sides. This is the only one leaking. It is not pouring out a tremendous amount but just a spray. Anyone have any ideas what is wrong?
Backflow need to be replaced?

This is really a job for a thermostatic freeze protection device that will release a flow of water all by itself when the freeze approaches.

As for the leaking valve itself, and not looking at the application, a version designed to work 24/7 without leaking would be this
