Strainer comes before the RPZ, and yes, you can get an RPZ with a brass strainer already installed on it. Personally, if I had to have a strainer, I'd special-order one with a 100 mesh screen, and really protect the RPZ (and sprinkler system, too) from any debris.

Air gaps are for connections to a drain line, and you don't have a drain line when an RPZ is installed outdoors.

So strainer suppose to be installed right after RPZ where pipe goes outside?
Is there need for Air Gap if my RPZ installed outside of my house?

Air gaps are for inside installs, so you can run any dribbling water into a drain line. The strainer is a form of insurance, to stop debris from messing up the works.

Air Gap and Strainer

According to our village requirements along with RPZ I need to install in-line strainer
and air gap. I'm thinking about Febco 3/4" 860 RPZ model. What is the in-line strainer and what is air gap? Why do I need them? Are there any special things I have to know about them? Can I buy it with RPZ at www.sprinklerwarehouse.com or I need to go to local plumbing shop?
Thanks,
Andrew
