Got this series of questions and comments from a Fire Marshal in a neighboring county. Any ideas? Q. I am looking for some low flow rate residential sprinkler heads. I can find 13 GPM heads but, would like to find one with a lower rate of discharge. Q. Ordinary or Intermediate Temperature? Q. Type of head- pendant, concealed, side wall, etc?? A. Either recessed or concealed pendant . 135 or 155. I am trying to work through a P2904 sprinkler system that has a ¾ supply feed at about 50 in length which limits me to 14 GPM. The houses at Stevens Tech had new water services installed recently and only installed ¾ pipe. Street is closed , sidewalk is poured and the front porch footers are in place. OOOOPOPPPS!! They forgot to put me in that loop.
