Unless something has changed since the last time I looked, USC does not approve DCVA's for health hazard applications, which IMO irrigation is, even if some jurisdictions don't think so.
On the issue of RPZA's, some of the Watts assemblies can be installed in a pit, however they also note it is not recommended and to refer to local codes.
Example.

It is generally recommended that back flow preventers never be placed in pits unless absolutely necessary and then only when approved by local codes. In such cases, a modified pit installation is preferred.
