All the plans I look at for a fire pump system associated with a sprinkler/standpipe system show a "Bronze check valve w/ 3/32" orifice in caliper" in line with the take off coming coming off the discharge line of the pump and going to the fie pump controller.
What is the reason for such a check valve, and what does " 3/32" orifice in caliper" mean ?
Thanks
