Who installs your RPZs

[GrazerZ]

Here in Maine we have to put in an RPZ for an irrigation system. It must be done by a plumber because it is located inside the building. Anything on the outside we can do or point of connection. My question is this, how do you deal with this issue? and how much do you typically pay a plumber to do this job? Just want to make sure about our pricing. thanx

I pay the plumber $100 and I buy all the materials. While he's at it he hooks up the backflow on the outside as well.

When they need to be done, I do it. I'm licensed for our area. My license and qualifications would probably not work in many of your areas though.
