Galvanic Reaction. Years ago I was installing the sprinkler system in a Post Office. When it came time for the punch list corrections, one item on the list was a 1/2" brass nipple in the otherwise galvanized piping for the alarm valve. Shaking my head in disbelief, I approached the inspector (Lieutenant, Army Corp of Engineers, newbie) and asked about it. He says that the brass nipple has to be removed due to possible galvanic reaction. I started laughing and pointed out that EVERY valve (drain valve, inspectors test, check valve..) in the system is brass and oh yeah, what about ALL the sprinkler heads, they are brass, what are we gonna do with them? He agreed and the nipple remained. Bottom line, No Electrolytes (salts), No Corrosion, at least in sprinkler systems.
