When reading NFPA 13 Handbook, 18.104.22.168. The figure shows several layout of valves installation. My question is what is the order to install the valves. Wet system figure shows control valve, then check valve; however the dry pipe system shows check valve first then control valve. So what is the right order to install valves? Or it doesn't matter as long as you have control and check valve?
