What plumbing can you DIY in Albany, New York?

[Don B.]

I'm getting into a home in Pine Hills which has outdated galvanized pipes, which are rusting and decreasing home water pressure. In Albany, I believe you need to hire a licensed plumber to do your plumbing.

Is it possible to do some of the work myself - for example laying out a new network of Pex tubing, and then hire a licensed plumber to do the last bit of "clicking it together?" Has anyone done this before?
