9/26/22 Please take in your channel locks to tighten OS&Y DH Sprinkler Service Call Service call for leak Deficiency: The Os&y valve located inside the restaurant has a small leak at the packing we adjusted packing as much as we could we tightened and re-tighten but this would not stop the leak completely it is our suggestion based on the corrosion on the nuts bolts things like that and the age of the valve that this valve be completely replaced I don’t think there is a rebuild kit out there that could be put in for this valve.
