(All rooms containing a backflow preventer are required to > have a drain and a relief drain.)
Thom - Could you give a reference for this requirement? I know there are requirements for RPZ installed below ground level. I have seen three buildings that were flooded by RPZ above ground installations where the water had no place to go. Is this requirement for DCVs as well?
