It’s too early on the west coast so Steve is probably asleep. 😀 I don’t have the standard so I don’t know what it says and I don’t understand the need for the check valves at the base.
However, if the standpipes are interconnected at the top, then I think there should be a control valve in that connection at top to allow sectioning off each standpipe separately from the other one if any repair work needs to be done on it. This would apply to both wet and manual systems. Just my opinion.
