Todd & Ron, Thanks for your input. I was planning on just using a butterfly valve at each floor but forgot about the drains. I don't think I'll check the floors off. Each floor is only about 2,500 Sq Ft.
Thanks again.

Randy, Code wise, I don't anything that restricts you from doing that. I always have felt uncomfortable with the idea of a standpipe on a dry valve, but perhaps some of the fire fighters amongst us could help up on the merits of those. The problem I see with the floor control on a dry system is that most floor controls contain flow switches, which are a no-no. You could install a valve, but probably not anything to monitor flow. Also, I'm not sure how the check valve requirement would play in to this. There is a restriction on using check valves to separate a dry system, but does that prohibit check valves for any reason? It could. Todd At 06:51 PM 4/9/2008, you wrote: >Forum Members, > > > >I have a two part question. > >1. Can I have a combined standpipe on a dry system?
