I'm guessing only having to add 8-10 new heads and the old grid is 10x10, very old screw pipe, Hodgeman uprights on 2x2x1/2 tees, probably as clean as a whistle inside (as usual). The current design is 12x14 for the 2x2 ceiling. It's funny, I think if they didn't need to add any they probably would have just done it themselves. His helper says they usually just do it themselves but never relieve pressure (!). I guess why even call the alarm guy if you don't have to.
TD Go Red Sox! as long as you calc includes the 5 ft eqv length of the BL tee (since the sprinkler is not attached to the tee) and that for the flexhead (about 10 ft), why not?
