Now these are very accurate. I have one and have used it many times.

Wow! That's a no b.s. tester, except I have no fire hydrants on any of my sites.

I did many hydrant flow tests at the company I used to work for. These tests were for fire protection and new subdivisions mostly. You haven't seen flow until you see 4000 gallons per minute coming out of a 2.5" hydrant bib at almost 200 psi. A ground shaking experience.

I use hydrant adapters to get a street pressure measurement when a home has a PRV. Most all hydrants have the 2.5 inch NST threads, but recently, I found some that had 2.5 inch NPSH threads.

I have both versions of hose adapters but have found that the flow gauge fit on every hydrant around here.

my pollardwater catalog #172 only has 160psi/2120gpm max gauges rated for 2.5 inch. Got a link to the 200/4000?

I had to swap the gauge. It broke the stock one. It's just a piezo tube with a standard size orrifice. Those pressures were on a hydrant I tested.

if you could post the link to the pressure/flow gauge i would be greatful. dual read gauges for the pressure/flow range you stated are tough to find. thanks

You have a single hydrant-to-garden-hose adapter for the NPSH threads?

i have one boots, posted pics of it 3 years ago.

I would tend to believe it was of the slightly larger NST threads - plenty of garden-hose adapters for them - the NPSH threads are about a quarter-inch smaller in diameter, and I don't see a a garden-hose adapter for NPSH hydrants
