The sprinklers are in surprisingly good condition. The property is only 5 to 7 years old. The existing rod is zinc plated and the existing rings are the standard galvanized swivel type rings. I explained the NFPA ferrous material requirement to the customer and have recommended installing all new stainless rod and rings.
*Venting time* However as it goes with most HOAs someone on the board is king of the world and "knows" every thing about everything. They inevitably know someone who knows someone who did it this way or that way. The professional recommendations mean nothing. With that being said, I am simply a lowly sprinkler guy who knows no one who did it that way. So I figured I'd ask instead of making up crap in the absence of facts that I may unaware of. (I'll stop now). *End Ranting* Thanks Todd, I don't believe I have ever come across this "specifically approved" non metal hanger material either. If someone has, please let me know. Thanks, Mark E.

NFPA 13 requires that all hangers be ferrous (contains iron, the primary component of steel), unless specifically approved. I do not know of a non-metallic hanger rod. Stainless would be the best option. You might be able to use regular plated rod if you coated it with spray galvanize in place, but I would have to do more research. BTW, how are the sprinklers? Are they coated? At 09:42 AM 4/13/2009, you wrote: >Non-Corrosive Hangers? Does any one know of an accepted and/or >approved method of hanging >(re-hanging) fire sprinkler pipe.
