First, for reasons that are more historical than understandable....the fire service's primary attack lines these days are 1.75" which it turns out uses 1.5" couplings. Why? Don't ask. It has a logical explanation but it does not matter....it just is. Second, talk to the local FD. Ask them what size connections they want to have? Yep, I know that 14 says that if 1.5" is provided....blah blah blah. But if the size of the connection is 1.5" to serve 1.75" FD hose...is it really a Class 1 system or simply a Class III system with threads to match that of the local FD which we are required to provide. I have eliminated this issue many times by simply indicating on the drawings that the system is designed as Class III but that reducers have been added per the FD's request to match their threads and tactics. Just my thought for today....now I am all out....time to go home. Paul Sincaglia, P.E.
