Couple things hit me- If your piping to the test header is over 15', don't you have to up it a pipe size? Got caught on this once by an arrogant FPE in an $800 trench coat. Don't want that to happen again. So if you're running the pump test header thru a crossmain, you'd have to confirm your delivery of the 150% of capacity, not just size the CM for the spkr demand.
Interestingly, I don't recall any requirements added for sizing of the UG or yard hydrants, or roof hydrant, if they are employed instead. And allowing these to be used sort of drops any sign of an intent by the committee to be emphasizing the test header should be in the pumproom. The language makes me think it has to work and do what we intended it to do- enable us to flow the pump discharge and measure it. BTW, wouldn't the systems be hamered by the weekly test run anyway? Does any one even go out to the pump room and do this manually, and WATCH THE PUMP as it does its run, and close then re-open the pump discharge valve? One of our customers has lost a couple of diesels during weekly test runs. Their corp policy is now to do it manually, and operator must monitor the engine for overheating, etc. In our most recent 2500 for them (that's gpm, not how many pumps)we put a horn/strobe outside the pump room door to alert any engine trouble signals- Since we know that's where the maint guy will be standing, having a smoke. Ought to scare the heck outa him, eh? George Church Rowe Sprinkler -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matthew J.

The heading 5.15 states "Discharge Pipe and fittings". So they all have to fall between the discharge flange to the system side of the discharge valve, pipe included. If this were not the case, I could make you size all piping downstream of a 1000 gpm pump to 6", even if your crossmain calcs for light hazard indicate 2½" R/ Matt Matthew J.
