how do you fix a slow leak at only one sprinkler head?
Answers:
replace the head
Other answers:
I'm assuming you mean a fire system sprinkler head. The fix is to turn off the pressure to the system and replace the head, cleaning up the pipe thread when doing so. This must be done only by a qualified and certified pipefitter to maintain any property insurance legally. The system must be inspected/tested and meet federal certification standards. Otherwise you might be charged with criminal negligence, and insurance being invalid you may be liable for any and all damages in event something nasty occurs. Quick fix - and it might not work - just tighten the head about 1/16 to 1/8 turn. If it takes more than that, don't mess with it - get it replaced properly!
