Plumbing code, glycol, and solar hot water
I'm putting in a solar hot water system. In my state, I am NOT allowed to do any plumbing that connects to city water or sewer.
Well, I got to thinking. My solar system runs a closed glycol loop, which is NOT connected to city water (has no direct water make-up to city water either). Am I correct to say that I can do the glycol loop myself since none of it connects to city water, and then get a plumber to hook my tank into the city lines?
