Ok I’m alittle confused with the pipe schedule for the preaction systemsnext to the wet system on that header. Why is it a 2 inch valve them right on top of the valve there a concentric reducer/increaser and the pipe size goes up then ties in to what looks like 4” along with another system? I’ve been in the sprinkler fitters union for 15 years running a service van for the last 10 and I’ve never seen that before.
I wish nick was still here

Because its just meant to show a bunch of different risers for learning components essentially. I wanna say that header wasnt even flowing
Typical fitter, what local?
