I think that you should have two check valves - one each on the sprinkler and standpipe risers, and four control vavles - one each for the risers and one each for standpipe sectional valves.

So we arent feeding the sprinklers from the standpipe. I was trying to figure out if i need a control and check. on the riser(for the whole system), another one on the main to the standpipe, and another one on the main feeding the sprinkler system. What do you guys think? Thanks for your help fellas.
