I've thought about this question for a while now and maybe someone here has a answer . You have a commercial bldg. where determining flow rate and pressure are crucial to determine water distribution design , and I've bein taught the city service is usually at a flow rate of 5 gpm. , but some systems are at 10 gpm . I have bein taught to install a 3/4'' hose bib near the meter [ and a lot of systems have it already ] , to provide a testing station . Then I basically open the bib full bore and see how many gallons per minute flow there is. I question the 3/4 bib opening as opposed to a 1" shut-off because you have fixtures inside supplied by 1". Areas which have low gpm. flow at the service then needs assistance of booster pumps , gravity tanks ,etc. Does anyone have a credible surefire way to determine gpm. at the incoming service . I was always told as close to the meter as possible for testing .Thanks
