Great point, Bob- imagine 8" UG, 8" riser, later on a 1" AF connection for a one or two head AF system off, say a 4" CM. Wouldn't be 1" RPZ?
Love it- the RPZ separating the non-toxic AF from our stinky sprinkler water with soot in it (just look at my dress!). Sure today's premix is tomorrow's Prestone, but I just don't see it going thru a 1/32" hole, thru a crossmain a couple hundred feet, thru a DCDA, and then into the domestic at the FF T to poison the occupants. But they're banning 32 oz sodas in NYC.... George L. Church, Jr., CET Rowe Sprinkler Systems, Inc.

I've never read anything that would suggest this in any manufactures literature. As well, how would that affect an antifreeze loop that's remote? Would you have to use the same size BFP as the piping it comes off of instead of reducing down to what the hydraulics allow?

My source (certified BFP tech) says this is a requirement of USC "listing". This was from a presentation at our State SFPE meeting on BFP's...Just wondering if everyone else knew this "requirement" (none of us did). Regards to All- Jerry accentf...@aol.com Jerry D.
