Coating on exterior sprinkler head

[fireguy]

In areas where exposed to weather and or high humidity, exposed to industrial processes, or exposed to corrosive water supply. Nothing worse than missing it and coming back three years later and seeing the aqua colored funk:View attachment 354

An area with corroded heads is the cutting room of meat markets, or other food processing areas that are washed down with a bleach solution. Bleach vapors will turn the heads green.

FG,



Hence “industrial processes” which classifies as the use of bleach, chlorine etc. since we also require them in the meat departments of groceries and super centers and hotel pool areas and equipment rooms.



Cda,



Like someone said before regarding the wider use of Teflon coatings, we request information regarding corrosion potentials and if their submittals indicate the manufactures coating is listed for corrosive atmospheres we accept them but if they turn aqua at a later date, they get replaced.

Well I'll be! I thought they were decorator heads in antique copper high lights!

Just had 12 of them replaced. Only been in about two years.
