Not that unusual for multiple placards. One MRA might need a hi pres w/low flow. Another lower pres, but more GPM.
It's for future generations to know what you were thinking. And LOL when people don't round to nearest 5 GPM, or have ANY significant digits right of the decimal point in pres. Saw a retail store, 22' high, with 17 PSI reqd at base of riser. How's that work? Zero loss piping? George L. Church, Jr., CET Rowe Sprinkler Systems, Inc.
