How do you guys calc these systems? Just the K22 section and the K17 section separately? Or a combo? I think there are situations where having one line of K17s (at 52 psi) in your remote area would be the "worst-case" scenario because that 52 psi would drive some overflow in the two lines of K22s (that only need 40 psi at that height). Or do you actually split the systems (zone boundaries) so that there isn't a system that has both types?
