Typically the cleaning solvents used are not brass/copper friendly. I'm guessing since the request was for stainless pipe the sprinklers will be exposed so they'll be some form of corrosion resistant heads (wax/lead?), I would assume the heads would be soft enough to seal well but I'll have to pass that question on.

Or will we need to get a variance based on it being "better"? We're working in a clean environment and are probably going to provide socket weld fittings or threaded fittings and back weld them (other than the heads obviously). Socket weld fittings are mentioned, but the only mention of stainless anywhere in the standard is the C factor table. Mike Morey, CFPS, SET Planner Scheduler/Designer BMWC Constructors, Inc. 1740 W.
