In Nov 09 had my 10+ year old fire suppression system refilled with antifreeze solution. Aprox 5 months later one of the sprinkler heads at the rear of the house sprung a leak (fluid was pink) and had to be retightened. Last week I noticed an accumulation what appears to be orange (rust?) colored moisture dripping very slowly from two heads at the front of the house. Checking all 18 heads, I noted small amounts of moisture just above the heads (where they "enter" the ceiling) and rust on about 8 of them. Is this all from condensation or do I have a more serious problem with these heads?
